Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor

Why Osana takes so long? (Programmer's point of view on current situation)

I decided to write a comment about «Why Osana takes so long?» somewhere and what can be done to shorten this time. It turned into a long essay. Here's TL;DR of it:
The cost of never paying down this technical debt is clear; eventually the cost to deliver functionality will become so slow that it is easy for a well-designed competitive software product to overtake the badly-designed software in terms of features. In my experience, badly designed software can also lead to a more stressed engineering workforce, in turn leading higher staff churn (which in turn affects costs and productivity when delivering features). Additionally, due to the complexity in a given codebase, the ability to accurately estimate work will also disappear.
Junade Ali, Mastering PHP Design Patterns (2016)
Longer version: I am not sure if people here wanted an explanation from a real developer who works with C and with relatively large projects, but I am going to do it nonetheless. I am not much interested in Yandere Simulator nor in this genre in general, but this particular development has a lot to learn from for any fellow programmers and software engineers to ensure that they'll never end up in Alex's situation, especially considering that he is definitely not the first one to got himself knee-deep in the development hell (do you remember Star Citizen?) and he is definitely not the last one.
On the one hand, people see that Alex works incredibly slowly, equivalent of, like, one hour per day, comparing it with, say, Papers, Please, the game that was developed in nine months from start to finish by one guy. On the other hand, Alex himself most likely thinks that he works until complete exhaustion each day. In fact, I highly suspect that both those sentences are correct! Because of the mistakes made during early development stages, which are highly unlikely to be fixed due to the pressure put on the developer right now and due to his overall approach to coding, cost to add any relatively large feature (e.g. Osana) can be pretty much comparable to the cost of creating a fan game from start to finish. Trust me, I've seen his leaked source code (don't tell anybody about that) and I know what I am talking about. The largest problem in Yandere Simulator right now is its super slow development. So, without further ado, let's talk about how «implementing the low hanging fruit» crippled the development and, more importantly, what would have been an ideal course of action from my point of view to get out. I'll try to explain things in the easiest terms possible.
  1. else if's and lack any sort of refactoring in general
The most «memey» one. I won't talk about the performance though (switch statement is not better in terms of performance, it is a myth. If compiler detects some code that can be turned into a jump table, for example, it will do it, no matter if it is a chain of if's or a switch statement. Compilers nowadays are way smarter than one might think). Just take a look here. I know that it's his older JavaScript code, but, believe it or not, this piece is still present in C# version relatively untouched.
I refactored this code for you using C language (mixed with C++ since there's no this pointer in pure C). Take a note that else if's are still there, else if's are not the problem by itself.
The refactored code is just objectively better for one simple reason: it is shorter, while not being obscure, and now it should be able to handle, say, Trespassing and Blood case without any input from the developer due to the usage of flags. Basically, the shorter your code, the more you can see on screen without spreading your attention too much. As a rule of thumb, the less lines there are, the easier it is for you to work with the code. Just don't overkill that, unless you are going to participate in International Obfuscated C Code Contest. Let me reiterate:
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.
Antoine de Saint-Exupéry
This is why refactoring — activity of rewriting your old code so it does the same thing, but does it quicker, in a more generic way, in less lines or simpler — is so powerful. In my experience, you can only keep one module/class/whatever in your brain if it does not exceed ~1000 lines, maybe ~1500. Splitting 17000-line-long class into smaller classes probably won't improve performance at all, but it will make working with parts of this class way easier.
Is it too late now to start refactoring? Of course NO: better late than never.
  1. Comments
If you think that you wrote this code, so you'll always easily remember it, I have some bad news for you: you won't. In my experience, one week and that's it. That's why comments are so crucial. It is not necessary to put a ton of comments everywhere, but just a general idea will help you out in the future. Even if you think that It Just Works™ and you'll never ever need to fix it. Time spent to write and debug one line of code almost always exceeds time to write one comment in large-scale projects. Moreover, the best code is the code that is self-evident. In the example above, what the hell does (float) 6 mean? Why not wrap it around into the constant with a good, self-descriptive name? Again, it won't affect performance, since C# compiler is smart enough to silently remove this constant from the real code and place its value into the method invocation directly. Such constants are here for you.
I rewrote my code above a little bit to illustrate this. With those comments, you don't have to remember your code at all, since its functionality is outlined in two tiny lines of comments above it. Moreover, even a person with zero knowledge in programming will figure out the purpose of this code. It took me less than half a minute to write those comments, but it'll probably save me quite a lot of time of figuring out «what was I thinking back then» one day.
Is it too late now to start adding comments? Again, of course NO. Don't be lazy and redirect all your typing from «debunk» page (which pretty much does the opposite of debunking, but who am I to judge you here?) into some useful comments.
  1. Unit testing
This is often neglected, but consider the following. You wrote some code, you ran your game, you saw a new bug. Was it introduced right now? Is it a problem in your older code which has shown up just because you have never actually used it until now? Where should you search for it? You have no idea, and you have one painful debugging session ahead. Just imagine how easier it would be if you've had some routines which automatically execute after each build and check that environment is still sane and nothing broke on a fundamental level. This is called unit testing, and yes, unit tests won't be able to catch all your bugs, but even getting 20% of bugs identified at the earlier stage is a huge boon to development speed.
Is it too late now to start adding unit tests? Kinda YES and NO at the same time. Unit testing works best if it covers the majority of project's code. On the other side, a journey of a thousand miles begins with a single step. If you decide to start refactoring your code, writing a unit test before refactoring will help you to prove to yourself that you have not broken anything without the need of running the game at all.
  1. Static code analysis
This is basically pretty self-explanatory. You set this thing once, you forget about it. Static code analyzer is another «free estate» to speed up the development process by finding tiny little errors, mostly silly typos (do you think that you are good enough in finding them? Well, good luck catching x << 4; in place of x <<= 4; buried deep in C code by eye!). Again, this is not a silver bullet, it is another tool which will help you out with debugging a little bit along with the debugger, unit tests and other things. You need every little bit of help here.
Is it too late now to hook up static code analyzer? Obviously NO.
  1. Code architecture
Say, you want to build Osana, but then you decided to implement some feature, e.g. Snap Mode. By doing this you have maybe made your game a little bit better, but what you have just essentially done is complicated your life, because now you should also write Osana code for Snap Mode. The way game architecture is done right now, easter eggs code is deeply interleaved with game logic, which leads to code «spaghettifying», which in turn slows down the addition of new features, because one has to consider how this feature would work alongside each and every old feature and easter egg. Even if it is just gazing over one line per easter egg, it adds up to the mess, slowly but surely.
A lot of people mention that developer should have been doing it in object-oritented way. However, there is no silver bullet in programming. It does not matter that much if you are doing it object-oriented way or usual procedural way; you can theoretically write, say, AI routines on functional (e.g. LISP)) or even logical language if you are brave enough (e.g. Prolog). You can even invent your own tiny programming language! The only thing that matters is code quality and avoiding the so-called shotgun surgery situation, which plagues Yandere Simulator from top to bottom right now. Is there a way of adding a new feature without interfering with your older code (e.g. by creating a child class which will encapsulate all the things you need, for example)? Go for it, this feature is basically «free» for you. Otherwise you'd better think twice before doing this, because you are going into the «technical debt» territory, borrowing your time from the future by saying «I'll maybe optimize it later» and «a thousand more lines probably won't slow me down in the future that much, right?». Technical debt will incur interest on its own that you'll have to pay. Basically, the entire situation around Osana right now is just a huge tale about how just «interest» incurred by technical debt can control the entire project, like the tail wiggling the dog.
I won't elaborate here further, since it'll take me an even larger post to fully describe what's wrong about Yandere Simulator's code architecture.
Is it too late to rebuild code architecture? Sadly, YES, although it should be possible to split Student class into descendants by using hooks for individual students. However, code architecture can be improved by a vast margin if you start removing easter eggs and features like Snap Mode that currently bloat Yandere Simulator. I know it is going to be painful, but it is the only way to improve code quality here and now. This will simplify the code, and this will make it easier for you to add the «real» features, like Osana or whatever you'd like to accomplish. If you'll ever want them back, you can track them down in Git history and re-implement them one by one, hopefully without performing the shotgun surgery this time.
  1. Loading times
Again, I won't be talking about the performance, since you can debug your game on 20 FPS as well as on 60 FPS, but this is a very different story. Yandere Simulator is huge. Once you fixed a bug, you want to test it, right? And your workflow right now probably looks like this:
  1. Fix the code (unavoidable time loss)
  2. Rebuild the project (can take a loooong time)
  3. Load your game (can take a loooong time)
  4. Test it (unavoidable time loss, unless another bug has popped up via unit testing, code analyzer etc.)
And you can fix it. For instance, I know that Yandere Simulator makes all the students' photos during loading. Why should that be done there? Why not either move it to project building stage by adding build hook so Unity does that for you during full project rebuild, or, even better, why not disable it completely or replace with «PLACEHOLDER» text for debug builds? Each second spent watching the loading screen will be rightfully interpreted as «son is not coding» by the community.
Is it too late to reduce loading times? Hell NO.
  1. Jenkins
Or any other continuous integration tool. «Rebuild a project» can take a long time too, and what can we do about that? Let me give you an idea. Buy a new PC. Get a 32-core Threadripper, 32 GB of fastest RAM you can afford and a cool motherboard which would support all of that (of course, Ryzen/i5/Celeron/i386/Raspberry Pi is fine too, but the faster, the better). The rest is not necessary, e.g. a barely functional second hand video card burned out by bitcoin mining is fine. You set up another PC in your room. You connect it to your network. You set up ramdisk to speed things up even more. You properly set up Jenkins) on this PC. From now on, Jenkins cares about the rest: tracking your Git repository, (re)building process, large and time-consuming unit tests, invoking static code analyzer, profiling, generating reports and whatever else you can and want to hook up. More importantly, you can fix another bug while Jenkins is rebuilding the project for the previous one et cetera.
In general, continuous integration is a great technology to quickly track down errors that were introduced in previous versions, attempting to avoid those kinds of bug hunting sessions. I am highly unsure if continuous integration is needed for 10000-20000 source lines long projects, but things can be different as soon as we step into the 100k+ territory, and Yandere Simulator by now has approximately 150k+ source lines of code. I think that probably continuous integration might be well worth it for Yandere Simulator.
Is it too late to add continuous integration? NO, albeit it is going to take some time and skills to set up.
  1. Stop caring about the criticism
Stop comparing Alex to Scott Cawton. IMO Alex is very similar to the person known as SgtMarkIV, the developer of Brutal Doom, who is also a notorious edgelord who, for example, also once told somebody to kill himself, just like… However, being a horrible person, SgtMarkIV does his job. He simply does not care much about public opinion. That's the difference.
  1. Go outside
Enough said. Your brain works slower if you only think about games and if you can't provide it with enough oxygen supply. I know that this one is probably the hardest to implement, but…
That's all, folks.
Bonus: Do you think how short this list would have been if someone just simply listened to Mike Zaimont instead of breaking down in tears?

Beginner's guide to Myriad Mining 4: Raspberry Pi edition

Beginner's guide to Myriad Mining 4: Raspberry Pi edition!
 
Part 1 - Mining Myriad with your Desktop PC (CPU) is here: https://www.reddit.com/myriadcoin/comments/6jj5z5/beginners_guide_to_myriad_mining_using_you
 
Part 2 - Mining Myriad with your NVIDIA GPU is here: https://www.reddit.com/myriadcoin/comments/6jobfa/beginners_guide_to_myriad_mining_part_2_using/
 
Part 3 - Mining Myriad with your AMD GPU is here: https://www.reddit.com/myriadcoin/comments/6lsic9/beginners_guide_to_myriad_mining_part_3_using/
   
Requirements:
 
-A Raspberry Pi
-Keyboard, mouse, network cable
-A PC for the wallet
-SD card (8 GB+)
-Patience
 
I'm personally using a Pi 2, however I'd be interested to know if there are hurdles/hashrate differences with any of the other Pi models.
 
I also have a few Pi heatsinks on order, and it seems you may even be able to overclock your Pi for this - I'll have a look into this and report back if there is any interest in running the Pi mining, overclocked with a heatsink. Commonly these machines are used to control Bitcoin ASICs, so this should be interesting!
 
N.B. Some of the initial steps are similar (or even identical) to the earlier guides. I recommend reading through it from start to finish, even if you think you're far ahead of me - sometimes there's a simple error that can be corrected by making sure all the steps are done in order.
 
  1. Get your wallet: Click on one of the following links https://github.com/myriadteam/myriadcoin/releases/download/v0.11.3.2/myriad-0.11.3.2-win64-setup.exe (or https://github.com/myriadteam/myriadcoin/releases/download/v0.11.3.2/myriad-0.11.3.2-win32-setup.exe if your computer cannot run the first) to download the Myriad official wallet. Install it on your PC, follow the setup instructions, then click "receive". Enter a label and press "request payment". This will be your wallet address for your Pi. If you did this for the CPU, AMD, or NVIDIA mining guides, you can do it again - there's no harm in knowing exactly where the payments are coming from, and there's no limit to how many addresses you can make to request Myriad. I'm talking about "request payment" - you only need one wallet application!
  2. Sign up for an account on a mining pool that takes Myriadcoin - Yescrypt. "Yescrypt" is the code that allows your Pi to search for coins on the network, and should only work with a CPU (central processing unit). The one I've been using for my guides is https://miningpoolhub.com/ . Once you sign up, click "Myriadcoin - Yescrypt pool" on the left, then click on "workers". Add a new worker - I called my first one CPU1, CPU2 etc for each new CPU, then Pi1, Pi2 etc for each Raspberry Pi. Password doesn't matter. In the difficulty box, you can put "sd=0.01" for a Pi 2 - thanks smatdesa , however sometimes just leaving it to auto-adjust can work better.
  3. After this click "wallet" on the left. Enter your "payment address" from step 1 and your PIN, as well as "20" for automatic payout of coins you mine, so you see some coin in your wallet every day or two. Please note, some pools charge a fee for this. 0.1 is the fee for my pool, and I'm happy to pay it to have the coins safely with me, as I don't donate - I have far too few Myriad to do so.
  4. This is where the guide diverges from the previous guides. If you're following along at home, this is a good place to start if you're in a hurry to get mining.
  5. Download Raspbian from this link: https://downloads.raspberrypi.org/raspbian_latest and click on "download ZIP under "Raspbian with desktop"(let me know if the link changes!). Whilst this is downloading, grab yourself a copy of 7-zip from www.7-zip.org ( http://www.7-zip.org/a/7z1604-x64.exe for 64-bit and http://www.7-zip.org/a/7z1604.exe for 32-bit ). If you don't know what "32-bit" or "64-bit" means, that's okay - generally, 64-bit should work fine.
  6. So, let's continue getting software ready. Install 7-zip by double-clicking on your downloaded file. Also grab yourself a copy of Etcher - for writing our Raspbian to our Pi SD card from this linK: https://etcher.io/ . Click "download for Windows x64". If this one doesn't work/install, click the little arrow to the right, and click "Etcher for Windows x64 (32-bit) (Installer).
  7. Now, with all of the required software in place to install Raspbian, let's write it to our SD card. Double click your Raspbian-Jessie .zip file, and drag the .img file inside into a foldeonto your desktop. After it extracts, open up your copy of Etcher, and click "select image" - pick the .img you just dropped. Select your SD card be careful here! make sure it's actually your SD card and click Flash.
  8. Start your Pi Once this is done, plonk your SD into your Pi, connect power, keyboard, mouse, and HDMI, and watch the pretty lights flashing! The next step is acquiring the mining software to get your Pi mining. On the desktop, which has a lovely picture of a road and some nature, if that's your thing. But we're here to get mining! Click on the fourth icon from the left (default) - Terminal - a little icon with a window and blue menu bar . You're presented with a CLI (command line interface) in lovely black and green.
 
Type the following into your CLI:
 
git clone https://github.com/tpruvot/cpuminer-multi
 
This should echo the following: "cloning into 'cpuminer-multi'...", and could potentially take a while - on my Pi 2 running Raspbian Jessie, it took me somewhere along the lines of half an hour for this step alone. You should end with "Checking out files: 100%" or something along these lines, and be returned to your blue $ CLI prompt. Next command is as follows:
 
sudo apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++
 
Hit "y" at the prompt to begin installation of the required packages.
 
The **next command happens to be the simple build command:
 
./build.sh
 
All done. Make yourself a cup of tea, and feel excited that your Pi is doing a thing (compiling). The next thing you know, it's all complete, and you're left staring at your lovely blue $ prompt. So let's get it working!
 
cd cpuminer-multi
 
This will get you into your folder. The following command should get you mining happily (yes!):
 
cpuminer -o stratum+tcp://hub.miningpoolhub.com:20577 -a yescrypt -u username.workername -p x -t 4
 
Explanation: We are using cpuminer to connect to the mining pool we joined in step 2. -a yescrypt is the algorithm we are using, username is the user name you joined the pool with, workername is the worker we added, all in step 2. -p is your password (it shouldn't matter - you could potentially put myriad2them00n, but let's not complicate things), and -t 4 is the number of threads - you can experiment with this, depending on your Pi - for my Pi 2, I get the most submitted shares with 4 threads.
 
Mining speed: To give you an idea of my experience: if you lined up 15 of these, all overclocked to 1 GHz, they would produce around the same hashrate as a modern i5 laptop (1.5 kH/s).
 
And that's it!. Shout out to smatdesa, who got me excited about working on this guide! Please post any new configurations, questions or comments below! Happy Myriad mining. And if your 3,166 Raspberry Pis are burning rubber and overflowing your coffers with XMY, or you just like what you see here, I'm humbly accepting: Donations (XMY only please):

Lore v2 QT on Raspberry Pi

Hello,
 
To follow up to mindphuk's excellent piece on building the headless client on Raspberry Pi (https://www.reddit.com/blackcoin/comments/6gkjrw/wip_blackpi_a_stake_device_based_on_raspberry/), I thought if anyone was interested I'd show you how to get the full QT version running on the Pi on the Jessie with Pixel desktop. This works and has been soak tested for several days now on a standard Raspberry Pi 3. I have since added some coins and it stakes a handful of times a day.
 
Running staking Lore clients paves the way for some of the future use cases of BLK utilising the Bitcoin 0.12 (and newer) core tech, including colored coins. So I'm going to leave this one going indefinitely to kickstart the number of Lore clients staking. It's certainly not mandatory but it will be good in the longer term to have a nice distribution of Lore staking clients.
 
The cross-compile which lets you create binaries for multiple platforms didn't work for the QT version on the Pi, so there is more to do than just running the binary unfortunately, as below. There are folks working on some much cleaner solutions than this for the Pi, with a custom front end, and where you won't have to do any mucking about. That is coming soon. In the meantime, if you enjoy a fiddle with such things, here's how to get this QT client working on your Pi.
 
These instructions assume you are starting from scratch with a completely blank OS.
 
Download Jessie with Pixel from: http://downloads.raspberrypi.org/raspbian/images/raspbian-2017-07-05/2017-07-05-raspbian-jessie.zip
 
Note they have since (August 2017) released a version called 'Stretch' which does not work with this guide. I'll see if I can come up with something new for that at some point and link to it here when I have. In the meantime the guide should work with the Jessie image above.
 
Unzip the file and extract the .img file to burn it onto Fresh SD card to boot from (to be safe, use 16GB or larger), using a tool like win32diskimager or Etcher.
 
Assuming you have keyboard/mouse and monitor plugged into your pi, boot it up and the Jessie Desktop will show.
 
Before we do anything else, you should increase the default swap size on the pi, as compiling certain libraries can exhaust the RAM and get stuck otherwise. To do this, launch a Terminal window and type:
 
sudo nano /etc/dphys-swapfile 
 
and Change the CONF_SWAPSIZE from 100 to:
 
CONF_SWAPSIZE=1024 
 
Exit nano with control + x to write out the file.
 
Then, run the following to restart the swapfile manager:
 
sudo /etc/init.d/dphys-swapfile stop sudo /etc/init.d/dphys-swapfile start 
 
Now, launch the browser and download the Lore 2.12 binaries for ARM here: https://mega.nz/#!k2InxZhb!iaLhUPreA7LZqZ-Az-0StRBUshSJ82XjldPsvhGBBH4 (Version with fee fix from 6 September 2017)
 
(If you prefer to compile it yourself instead, it is possible by following the instructions in the original article by Mindphuk just taking into account this is the newer version of the Lore client than when that was written (https://github.com/janko33bd/bitcoin/releases) and the versions of Boost and the Berkeley DB need to be the same as below.)
 
Double click the zip and extract the Lore binary files. Yes, at the moment they are all called 'bitcoin', not 'blackcoin' or 'Lore' - this is because the code derives from a recent bitcoin core implementation so this has not yet been updated. You can place these wherever you like.
 
In the Terminal window, change directory to where you put the binaries, e.g.:
 
cd Downloads/lore-raspberrypi-armv7-jessie-pixel chmod +x * 
 
That marks the binaries as executable.
 
Now, we need the Boost libraries installed for any of the Lore binaries to work. The project was done with Boost 1.62.0. Unfortunately the Jessie repository only goes up to 1.55, so we need to download and build 1.62 manually on the device.
wget https://sourceforge.net/projects/boost/files/boost/1.62.0/boost_1_62_0.tar.gz/download tar -xvzf download cd boost_1_62_0 sudo ./bootstrap.sh sudo ./b2 install 
 
(This will take almost 2 hours. Have a nice cup of tea and a sit down.)
 
When I came to run the binaries, I found they couldn't find Boost. Running this command fixes that:
sudo ldconfig 
 
Now we are going to install the packages which aren't already included in the default OS installation which the binaries need in order to run:
sudo apt-get install qrencode libprotobuf-dev libevent-pthreads-2.0-5 
 
Now we need to install the Berkeley Database version 6.2.23. This is the version Lore v2 uses. Bitcoin still uses 4.8 which is 10 years old! This doesn't take too long.
wget http://download.oracle.com/berkeley-db/db-6.2.23.tar.gz tar -xvzf db-6.2.23.tar.gz cd db-6.2.23/build_unix ../dist/configure --prefix=/usr --enable-compat185 --enable-dbm --disable-static --enable-cxx 
 
I find this next section of the Berkeley instructions worked better just switching to root, which can be fudged by running sudo su before the rest:
sudo su make make docdir=/usshare/doc/db-6.2.23 install chown -v -R root:root /usbin/db_* /usinclude/db{,_185,_cxx}.h /uslib/libdb*.{so,la} /usshare/doc/db-6.2.23 
 
Now we're going to go up a couple of directories to where the binaries were:
cd ../.. 
 
Then run the client!
./bitcoin-qt 
 
And there you have it. Should hopefully end up looking a bit like this: http://imgur.com/a/eEHGa
 
Using the Bootstrap can save a while syncing. Download it at: https://www.reddit.com/blackcoin/comments/6b3imq/blackcoin_bootstrapdat_up_to_block_1631800
 
Place the bootstrap.dat file into the ~/.lore directory.
 
Run ./bitcoin-qt again, it will say 'Importing Blocks' rather than 'Synchronising with Network'. My pi sync'ed fully in about 5-6 hours.
 
If you want peace of mind that Lore will always start on bootup into the Jessie w/Pixel desktop (i.e. after a power cycle), then you need to create a .desktop file in the following place.
sudo nano ~/.config/autostart/Lore.desktop 
 
And in it, enter the following (tailoring the Exec line below to the whereabouts of your bitcoin-qt file):
[Desktop Entry] Name=Blackcoin Lore Comment=Mining without the waste Exec=/home/pi/Downloads/lore-raspberrypi-armv7-jessie-pixel/bitcoin-qt Type=Application Encoding=UTF-8 Terminal=false Categories=None; 
 
Power usage and payback time
 
After a good while leaving it going by itself, the CPU load averages got down to almost zero, all of the time. Idling, the Pi uses a bit less than 3 watts. This means it would take two weeks to use one 1Kw/h of electricity.
 
If you pay e.g. 12.5 cents a unit, that's what you'd expect this to cost to run in a fortnight. That's around $0.25 a month or $3 a year. Green and cheap and helping to secure the BLK network. I paid for the year's worth of electricity in 2 days staking with 25k BLK. Makes mining look silly, huh? ;)
 
Securing your Pi
 
With staking, your wallet needs to be unlocked and as such, the keys to your wallet are on the device. In a clean and newly installed environment as described above, and if you don't allow others to use your device and there is no other software or nasties running on it, there is no real cause for concern. However, there are some basic security precautions you can take.
 
Firstly, if you have enabled SSH and are playing with your pi across your LAN (or worse, the Internet), you should immediately change the password for the default 'pi' user (which is preconfigured to be 'raspberry'). Simply log in as normal, then type:
 
passwd 
 
You'll be prompted to enter the old and the new passwords.
 
Security by default
 
Your Pi is likely, by default, to not be exposed to incoming connections from the outside world because your router is likely generating a private address range for your LAN (192.168.x.x or 10.0.x.x or 172.x.x.x) which means all incoming connections are effectively blocked at the router anyway unless you set up a 'port forward' record to allow packets arriving on certain ports to be forwarded to a specific internal IP address.
 
As for accessing your Pi across the internet, if you have set up a port forward, this likely has security ramifications. Even basic old fashioned protocols have proven in recent times to have uncaught flaws, so it's always advisable to lock down your device as much as possible, and even if you only plan to access the Pi over your LAN, install a firewall to configure this. I used one called ufw, because it's literally an uncomplicated firewall.
 
sudo apt-get install ufw sudo ufw allow from 192.168.0.0/16 to any port 22 sudo ufw --force enable 
 
This allows just port 22 (SSH) to be open on the Pi to any device on my LAN's subnet (192.168.0.x). You can change the above to a single IP address if paranoid, or add several lines, if you want to lock it down to your LAN and a specific external static IP address (e.g. a VPN service you use). To find out what subnet your router uses, just type:
 
ifconfig 
 
and you'll see on the interface you are using (either hard wired or wifi) the 192.168 or 10. or 172. prefix. Change the above rule so it matches the first two octets correctly (e.g. 10.0.0.0/16 if you're on a 10.0. address).
 
You may already use VNC to access your Pi's desktop across your LAN, this uses port 5900. Add a line like above to lock it down to an internal address. It's not a good idea to expose this port to the wider world because those connections are not encrypted and potentially could be subjected to a MITM attack.
 
You can query the status of the firewall like this:
ufw status 
 
And of course, try connecting remotely once you change the rules to see what works. You should consult the official documentation for further options: https://help.ubuntu.com/community/UFW
 
Back up & Recovery
 
There are again many ways to tackle this so I'll just speak about my basic precautions in this regard. Don't take it as a be-all-and-end-all!
 
The wallet.dat file is the key file (literally) containing all the private/public keys and transactions. This can be found in:
 
~/.lore 
 
You can navigate there using Jessie w/Pixel's own file manager or in a terminal window (cd ~/.lore). You can copy this file or, if you'd rather keep a plain text file of all your public and private keys, use the 'dumpwallet' command in the console. In Lore, go to Help > Debug Window > Console and type 'dumpwallet myfilename' where myfilename is the file you want it to spit out with all your keys in it. This file will end up in the same place you launch bitcoin-qt from.
 
The instructions earlier on, when running Lore for the first time intentionally left out encrypting your wallet.dat file because in order for the wallet to stake upon startup, it needs to have a decrypted key already. This isn't perfect, but after a power cycle, it would never stake unless you left it decrypted. So the best practice here is as soon as the wallet.dat file has left your device, i.e. you copy it to a USB stick for example, put it in an encrypted folder or drive (or both).
 
In Windows, one way is to use Bitlocker drive encryption for the entire drive. You should follow the instructions here to encrypt your flash drive before your wallet.dat is on there, and don't forget the password!!
http://infosec.nmsu.edu/instructions-guides/how-to-enable-bitlocker-to-go-for-external-hard-drives-and-usb-flash-drives/
 
On the Mac, I use a software package called Concealer to encrypt files I store on the Mac itself: http://www.belightsoft.com/products/conceale   There are almost certainly free packages with similar functionality, I have just used that one for years.
 
Either way, if you want to just make sure your USB drive is encrypted, you can do so in one-click in Finder before you put the sensitive files on it: http://lifehacker.com/encrypt-a-usb-stick-in-finder-with-a-click-1594798016
 
Note that these disk encryption methods may mean having to access the USB stick on a PC or Mac in order to retrieve the files in the event of a disaster. Be aware this may mean exposing them to more security issues if your computer is in any way compromised or someone nefarious has access to your computer. There are more 'manual' ways of backing up and recovering, such as literally writing down private/public key pairs which this guide doesn't go into, but may suit you better if paranoid about your setup.
 
Recovery
 
The wallet.dat file has everything in it you need to recover your wallet, or if you used 'dumpwallet', the file you saved out has all the keys.
 
Wallet.dat method: Install Lore as normal then replace any auto-generated wallet.dat in ~/.lore directory with your backup. If a lot of time has elapsed and many transactions have occurred since your backup, launch lore with:
./bitcoin-qt -rescan 
 
And if that doesn't do the job, do a full reindex of the blockchain:
 
./bitcoin-qt -reindex 
 
If you used the dumpwallet command, install Lore then place the file containing all the keys that you saved out in the same directory as bitcoin-qt. In Lore, go to Help > Debug Window > Console and type 'importwallet myfilename' where myfilename is that file containing all the keys. The wallet should automatically rescan for transactions at that point and you should be good to go.
 
There are a million ways to do effective security and disaster recovery, but I hope this shows you a couple of basic precautionary ways. There are discussions about better ways to stake without compromising too much security which are happening all the time and developments in this regard will happen in time.
 
In the meantime, feel free to comment with your best practices.

Project Blockchain Valley

PROJECT BLOCKCHAIN VALLEY
My name is Morgan Rockwell, I am CEO of Bitcoin Kinetics Inc. Now founder of Kinetics - Blockchain, Automation & Energy. I created the first Bitcoin Operated Service Machine to allow Bitcoin to be used in the real world in all machines & businesses. We are rapidly expanding & growing into new territories, industries and concepts to help build the Bitcoin & Blockchain based industries into a competitive & profitable environment. We have began the process of issuing equity on the NYSE in New York City. We have purchased a new building to house the buildings office & factory. We have made several partnerships with many Bitcoin Business Leaders, Ethereum, Micro-controller & Chip Makers, DIY companies and many more important players in the new technology industries. We now need your help before we are forced to ask help from the banking sector, tyrants or billionaires..
We now need 10000 Bitcoins to create the greatest Bitcoin Based Economy the world will ever see, including the first Bitcoin Town... Ill give you keys to the company, all of the equity, I do not want a dollar.
There will be always be a loan offer out there for the purchase of the main street property of 1000 BTC for immediate purchase & payback with base interest rate of 15% on the 1000 BTC - giving 1150 BTC payback in 5 years or equivalent in USD value of equity in the corporation we are creating to be listed on the NYSE. When that loan contract is fulfilled by someone there will be another 1000 BTC loan contact available within 7 days for someone else to bid on. The bidding price will be based on a lower competitive interest rate and this will be done Over The Counter through personal communications.
We require an immediate range of 7000-10000 BTC to build the entire region into a fully functional Blockchain based industry zone. This will be self sustaining in regards to energy consumption & economic production. A am building partnerships with many smart people, strong businesses and influencers in industry to get these goals accomplished. I need the lending community, the Bitcoin community, the cryptocurrency communities to help make Blockchain Valley become a reality.
Anyone up for that offer? It would be able to change the world if you can contact me & send me that I have contracts ready and waiting.
This is where the future begins.
Along side that move a NEW company is created, to compete with the likes of Google, Apple, GE, Visa & CHASE. It will be called "KINETICS Inc".
Kinetics - Blockchain, Automation & Energy www.Kinetics.cc
KINETICS is facilitator of several Bitcoin & Blockchain projects including:
KINETICS is going to be incorporated in Delaware as a C Corporation. The fully functional business such as #BitcoinKinetics, #BitcoinAcademy & #Axiomity will be managed, funded and operated by KINETICS Inc.
KINETICS Inc & Bitcoin Kinetics Inc will both be located at our new shop in Upper Lake, CA in Lake County.
9450 Main St, Upper Lake, CA 95485
This buildings rent is $800 per month, to be reduced from $200,000 price for full cash purchase of property. I have plans to purchase the entire building full cash in the next 90 days, until then i'm moving in 7/13/2014 SUN & paying rent to own for 90 days. I have been told I can purchase the entire block including over 20 different store fronts, garages, a bank, a post office, a saloon, a large antique shop, several window display store front shops and even large areas of land for crypto mining data centers, fields of solar panels & wind generators, as well as the fact that all of California's fresh water is within 2000 yards of the building in several lakes. There is over 100,000 sq ft of empty store & office spaces on the main street. All of it has been personally offered to me.
We are committed to partnering with #TeslaMotors to convert the old gas station into a Tesla Super Charger Station equipped with SuperChargers, solar power & a lounge to busy the drivers as they charge their vehicle. We will be creating a Bitcoin ATM friendly lounge where customers can purchase all things Bitcoin, Hardware & even use Bitcoins at all the local shops. Ill be putting www.CryptoCrates.com in one of the shops on the block giving the worlds first Bitcoin Record Store a physical location.
There are now many possibilities with this HUGE opportunity here before us all. We are in talks with #Ethereum and several lenders, venture capitalists, bankers & Bitcoin investors to make this dream of a physical Bitcoin world a reality. We can turn Upper Lake into the start of what will be the home of #BitcoinTOWN, a place where all Bitcoin Business will want to come and have their offices. Eventually growing into a "#BlockchainValley"
There is so much money involved & needed for this long term 100 year plan, In the next 10 years up to 10,000 BTC will be needed to pay:
If you build it, they will come.
There is much to be done, its is all the start of jobs, money & Bitcoins value going to the moon. Building something in the real world with Bitcoins lending technology.
I have over 15 years of construction, civil engineering, electrical engineering & business development. I am the best human on earth to get this mission accomplished and to get the job done. We are in a state ware Bitcoin is now legal tender, the time is NOW. I can make everything happen, i talk well, i don't sleep and work non stop until the goal is reached, i have networked with everyone from the rich to the poor, to the entire Bitcoin community. This is an opportunity to be within 1 1/2 hours of San Francisco and 2 hours from Sacramento. This deal with Tesla Motors gives me the ONLY charging station in this North California region giving the loop from San Francisco, Mendocino, & The i5 to Sacramento a complete loop allowing the Tesla vehicles to travel up into the Forest Area. This will bring HUGE revenue, HUGE partnerships & many many new Bitcoin users and Kinetics customers will all be flocking up from San Francisco to the new land of Bitcoin...
All of you should help us and ill personally make you a very rich Bitcoiner, and you will save the world from fiat, from centralization & from tyranny...
To purchase the main street property only need 1000 BTC as soon as possible with 1150 BTC payed back in 5 Years. That is a 15% payback on a 1000 BTC loan that can be bid on by lenders If you can even participate in this loan in fractions, partial or full, please contact us ASAP as moves need to be made immediately. This allows us to acquire the main drag of Main Street, Upper Lake, CA and all of its shops.
We will convert it into a Solar Roadway/SolarCity filled block, with Bitcoin ATMs on every corner, Bitcoin Laundromats, Bitcoin Bank, Bitcoin Friendly Shops, A Blockchain Node in every business, A Tesla Charging Station right in front of the 1920s original Gas Station, a Restaurant Called Satoshi's Grill, with 5 star Chefs already ready to join the team, a record and music shop that takes all crypto currency, The Bitcoin Academy giving a local education center for all to access the newest information, technologies and educators, a Coffee shop friendly to all things Bitcoin & The Blockchain, giving rise to Bitcoin Gift card usage, lounge environment with data center tools. The entire town will have a 4G tower system with the first going behind the Gas Station in the yard & FREE WIFI, LIFI & MESH networking covering the entire area.
We ask you the #Bitcoin Community for funding before we ever ask a Banker, so please help us before we are forced to go ask Goldman Sachs for fiat... The community can gather 1, 10, 100, 1000 or 10000 Bitcoins to make Bitcoin usable in all machines. As a loan of 15% would be very helpful to us and to you in circulating Bitcoin & funding this community venture.
Contact us if you are willing to support this new venture as time is of the essence, moves need to be made NOW, and your Bitcoin's future depends on people like us & you giving Bitcoin real world use. Help us bring the future into the now...
THE BITCOIN TOWN / BLOCKCHAIN VALLEY PLAN
These 10 Phases will take money, people, passion and motivation. Time will only get in the way if you don't become involved with both your Bitcoin, Your Mind, & Your Sweat, Blood & Tears. We will help make this a reality, but first comes capital, participants & the plan. We are all here to help grow into a better world, Bitcoin gives us that last chance for humanity to stand up and shake off its slack. If we can come together and show the world how this technology works in the real world, the planet will see, it will feel, it will hear and know Bitcoin as reality. Over night the world can change if we put out foot down, take a stand, and create the world as we see it to be. People are at war, starving and suffering in the most horrible ways, all I personally can do is fight the good fight with Bitcoin in my hand, there is a chance now for us to have sanctuary and a place to build our plan of attack from. We now have shelter, not just for Kinetics, but for the entire Bitcoin community of users, businesses & investors. You all now will have a safe and friendly place to live, work, shop, learn and grow...
I thank you for your time and your care for the world. Thank You.

[uncensored-r/Bitcoin] Blockstream vs miners – looking at the incentives around the SegWit2x fork

The following post by Scott_WWS (has been notified) is being replicated because the post has been silently removed.
The original post can be found(in censored form) at this link:
np.reddit.com/ Bitcoin/comments/7a6ew5
The original post's content was as follows:
In reading this article, the idea is proposed that there is a war on between miners and off-chain developers for revenue. Maybe a bit simplistic but the way this article reads, smaller block size inhibits the miners and allows more off chain business for companies like Blockstream.
Maybe I'm reading it wrong but to my eye, this looks like scaling progress is stymied to make off chain solutions more profitable.
If so, that doesn't seem to jive with what I know about bitcoin.
The article:
Blockstream vs miners – looking at the incentives around the SegWit2x fork
The past few months in the Bitcoin community have been filled with discussion of an upcoming hardfork – SegWit2x. There have been a lot of people voicing their opinion on the matter of whether that fork should be allowed to pass or not, but today I would like to look at who I believe to be two key players in this debate – Blockstream (opposing SegWit2x) and the miners, the core signatories of the New York Agreement. More specifically, I will be focusing on the incentives both of those parties have when it comes to dealing with SegWit2x.
What is SegWit2x? SegWit2x was first proposed as a compromise between the various factions in Bitcoin that were trying to solve the problem of blocks being full. It aimed to both enable the activation of SegWit to enable off-chain transactions, and to increase the block size to 2MB to increase the number of transactions that can be processed on-chain. It was to be deployed in two stages – first by activating SegWit in the summer (which already tookplace), and then by increasing the block size in winter (which is still pending).
Basic incentives for everyone When examining why people would be for or against a certain change, it is often useful to look at the incentives they have for being on either side of the fence. An incentive shared by every Bitcoin user and company is to see Bitcoin succeed, be used by more and more people and to gain in value. You can occasionally see someone stating the opposite (along the lines of “it’s good the price is going down, it will slow the adoption rate so the project will be developed further before mainstream starts to use it”, or people wanting to buy the dip in price), but most people that are invested in Bitcoin want to see it grow, that’s pretty much a given.
Beyond that, things tend to get murky. You can see some ideologies come into play and so on. But if you focus on SegWit2x, the basic incentive for both sides appears to come down to the good old money…
Incentives of Blockstream and the miners Blockstream is a for-profit company. As such, it is expected it will increase in value and, at least eventually, start generating revenue. While it had some projects that seem to be a money sink, the core business plan seems to still focus on sidechains – “sell[ing] side chains to enterprises, charging a fixed monthly fee, taking transaction fees and even selling hardware” (which the Blockstream CEO even explicitly confirmed). The original SegWit proposal was introduced by Blockstream’s co-founder.
So with this, we have a clear picture – Blockstream’s revenue stream will come from off-chain transactions. Now, let’s look at the other side of the debate.
Miners are paid directly in BTC by the blocks they mine. They mint new coins with each block, and they also collect fees for any transactions they include in that block. At the moment the block reward is 12.5BTC, and the fees add up to about 0.5 to 2 BTC on average. Pretty straightforward and as described in the original whitepaper.
So the miners are incentivised to include as many transactions in their blocks as they can, giving priority to those that pay more fees than the others per unit of size.
Clash of incentives Both sides of this debate get their money from the same source – transaction fees. Blockstream wants more transactions to flow through their proprietary service to collect more fees from institutions and individuals. The miners on the other hand benefit from more transactions taking place on the blockchain – they earn transaction fees only for the transactions that are included in the block and get nothing from off-chain transactions until they come back onto the chain. With finite amount of money flowing through the network, this is a classic zero-sum game – the more transactions flow through your preferred channel, the more money you have and the less money your opponent has.
In an ideal scenario, we would let both of those options onto the free market and let the consumer choose what they want to use. Some would choose off-chain transactions for their speed, others would prefer on-chain transactions for the immutable records, etc. In a truly free market, the best product will win and the market will reach equilibrium. However, one side is currently at a disadvantage.
The size of the blocks is currently fixed at 1MB and SegWit has been activated on the network. This means that the miners have a finite amount of space to work with, while Blockstream and similar service providers don’t have to do much to promote themselves – when the consumer will see on-chain transactions being too expensive for them and the blocks being full, they will by necessity make their way onto their platform to be able to transact.
Moreover, SegWit transactions have a smaller “weight” to them, meaning you can put more of them in a block and even go over the 1MB block limit with them.
So we have a company that benefits from the traditional blocks being filled, while also giving preferential treatment to on board onto and off board from its proprietary services, while blocking others from increasing the overall throughput, all for “the benefit of the consumer”. This is basically the Net Neutrality battle all over…
Dynamics of power Looking at this only from the lens of money is of course a bit of a simplistic view of things. There is probably a lot more politics, ideology and power in play – SegWit2x is a hard fork to the Bitcoin network being pushed by the miners rather than the traditional core developers. If it is allowed to pass, it will show that they don’t have full control over the project and thus remove them from a position of power, while giving the miners more power on top of the computing power they already hold.
Conclusions If you look at things from pure monetary perspective, the fight over SegWit2x is a fight about where the transaction fees will flow – whether they will be on or off the chain. Increasing the block size will mean more money will be going to the miners, while keeping it low will force more money to flow through SegWit-enabled services, and to a degree, through Blockstream.
SegWit2x is also a struggle for power in the space – who will be able to make changes to the protocol and how things will be handled in the future.
The struggle might be framed in many ways – allowing an average user to run Bitcoin on RaspberryPi, the centralisation of power in the hands of the miners or core developers, an attack on the Bitcoin network, etc. How much of that is genuine concern and how much of it is propaganda from either side it will be hard to discern.
But in the end, it’s probably about money and power…

Questions Answers
As a maker, why should I sell my goods on your site instead of amazon? As a buyer, why should I buy from you instead of amazon/ebay? Great questions - as a maker, our rates are lower than Amazon - flat 5% of the order. We also reach a core audience of people like you, which tends to mean you'll sell more on Tindie vs Amazon. As an example, one seller sold exclusively on Amazon, opened a Tindie store, and we began out selling Amazon. He closed his Amazon store and now sells exclusively on Tindie.
As a buyer, you are joining a community of likeminded people from all over the world and in different niches. Some like audio, some drones, others lighting. In the new year we are launching more features to build out the community side of the site. We are a community marketplace - community comes first. We can do a better job on the community side, and those features are currently being built.
As an example, one seller sold exclusively on Amazon, opened a Tindie store, and we began out selling Amazon. He closed his Amazon store and now sells exclusively on Tindie. Amazon has a flat fee you must pay $40 a month When you sell out many times over, inventory management becomes a huge issue.
Many reasons but here are two- * * Amazon has a flat fee you must pay $40 a month.* Easier inventory management when you have to just make sure 1 site is right vs multiple. When you sell out many times over, inventory management becomes a huge issue. But, that's three reasons. How can you run a successful business if you can't even count? Link to static.fjcdn.com
I have a desire to learn a programming language and have messed around with python and java on codeacademy. What would you recommend as the next step? Books? More beginner tutorials? Poking around on github? Sounds like you are now at the crossroad where people either keep going, or 'never have the time.' When I started, I'd get the occasional comment online, 'You'll never figure it out.' It's a pretty accurate statement for most. Most don't figure it out. If you can put your head down and just grit it out, you'll get to the other side.
If you want to grit it out, start with Learn Python the Hard Way. Then figure out a project you want to build and go build it. You'll pick things up as you go. You'll think you have it about 10 times before you really have a solid understanding. There were many times I'd talk to my friends and say "Oh I figured it out." I was wrong 10 times :)
It took 1 year to get to n00b level. The next year is when things settle in. After 2 years, you'll have a solid foundation to keep honing your skills. You won't know everything, but you can hack together projects, & figure things out.
Also checkout Stackoverflow. Learning how to properly break down my problems into questions was a great exercise. It helped me understand what the real problem is vs what I thought it was.
Did you eventually start working as an engineer or was programming geared towards side projects and building Tindie? I did - my first job after learning how to code was as a developer advocate. Not 'coding' but putting what I learned to good use. That company was acquired, and I eventually became a web engineer at the company which acquired us. That was my last job before starting Tindie.
My local hackerspace, a 501(c)3, is just getting started. We're thinking of making some products to generate some funding... would Tindie be the right marketplace for us? Oh cool! Yep! We have members of hackspaces all over the globe on Tindie. Sounds like a perfect fit. If you have any questions, just pm me and we can help!
What sort of things did you do for market validation? Good question - the only market validation I did was ask the question on /Arduino. There wasn't a marketplace for this type of hardware (we are still the only "big" site doing what we are doing). The space is emerging now.
Did you have personal experience with this type of thing, people you knew who needed something like this, or some other type of research? You are right. The big question I got from investors is actually - 'How big is the market?' Unfortunately there isn't a good answer for that bc the market is growing / being defined now. Arduino/Raspberry Pi/Drones/3D printers are all just getting started and all growing like weeds. If those platforms become as big as we think they will, then a site like Tindie will have to emerge.
Also, how do you go about estimating market potential? The one thing we look at is the components market is a massive, multibillion dollar market. The type of components that are on Tindie, generally speaking, first come to market on Tindie. The market potential is entirely untapped. However having orders from gov't agencies & large businesses is very reassuring that there is a much greater opportunity than just hobbyists (which is what most people thing on first glance).
What's been your biggest challenge as CEO of your own start-up? Great questions -
What's the most frequent challenge you saw when working across various start-ups in the Valley? Biggest Challenge as CEO - Communication, balancing expectations, keeping everyone on the same page from users, employees to investors. You'll constantly hear, "Did you see X?" when someone thinks it is a competitor. Chances are it isn't and they have their own idea of what the business is which is different than your own.
What words of wisdom do you have for someone wanting to create their own start-up? Wisdom to start a startup - If it is a tech startup, one of your cofounders must be technical. Either yourself or your cofounder. If you can't build the first version/ a proof of concept yourself, start there. If you aren't technical, and don't know anyone technical, learn. In the valley you hear, "I'm looking for a techincal cofounder." so many times its crazy. You either already know someone (a good friend usually) or you don't. Trust me , you won't 'find' a techincal cofounder.
Thanks for your time (and sorry for all of the questions) No worries - these were excellent questions. Keep 'em coming!
You'd be shocked how many random emails I get with businesses proposals. Are these the recreate facebook type of deals where you do all the work and they get to be the owner for giving you the idea of facebook? It runs the gamut from sales, hiring, marketing, partnerships, you name it.
Did you have a good breakfast? Eh, coffee, leftovers, and IRC. We have a channel on Freenode I hop in every morning to check in with users (Tindarians) and make sure everything is right with the world.
(hash)tindie on Freenode ftw
You've mentioned a few times how you shouldn't outsource development to a third party. Can you elaborate on this? Why not? What was your experience? What should you do instead if you're a n00b coder (like myself)? Sure thing - if you hire a 3rd party, you will always have to pay someone else to iterate on the site. There is a 0% chance it will be right on the first shot. Therefore its really an invitation to spend a lot of money down the road - not just the upfront cost you are spending to get your idea made. This is what I did with Knowble - it cost something like $20k+. Please learn from my mistake :) You'll have to iterate, make changes, learn as you go. If you know how to code, then you can make those changes yourself. You'll do it in the morning/nights/weekends and it will only cost you your time.
What advice do you have for me as a student? Thank you, I think what you're doing is awesome! Very cool! Getting press / outside attention is very difficult (if you don't pay for PR - we don't pay for PR). Write blog posts, like to those sites. The link love will go a long way (over time). Most of the companies that you read about on TechCrunch, PandoDaily, etc are paying for PR which is why they get listed on all of those blogs and have stories come out at the same time (embargoes). As a student, build something! Just keep building things. You have some free time - take full advantage of it. Also meet your peers. Build a network of other students in your class. Some will go to Google, Twitter, the next Google, the next Twitter. Increase your chances of doing well by meeting as many super smart people as you can. Build projects with them. Just make things and learn from experience.
I'm also a CS student and for the longest time I've been interested in Arduino. How did you get started tinkering and where would you recommend someone such as myself begin so as to eventually purchase from your website? There are tons of beginner Arduino books. Arduino also has some great tutorials: Link to arduino.cc
In this age, if you have a CS background, Google is your friend :)
Did some more reading. I personally feel a lot of excitement for how well you're doing lol, congrats! What we're you doing before the 5 year run in the valley? How did you get started there? Learn to do the things you don't know yourself.
NEVER outsource development to a 3rd party company.
Learn how to code.
If you don't know how to code, don't bring on another person that doesn't know how to code.
So what compelled you to go from NC to CA? How did you start getting acquainted with people there? Joined Yelp. Yelp was maybe 40-50 people at that point. Flew myself for the interview, got the job, packed my car and hit the road.
As an aspiring entrepreneur myself, my question is this: what was the process like of getting the company from an idea to something you would be able to pitch to investors? The site was already live, we had products, orders, traffic. The sales early on were ~doubling month over month. Sure they were small but that seems like a very good sign. As it kept growing, people around me connected me with other people interested in the space. The first investor I got was someone that was in my network already, but I didn't know him. He also invests in early stage companies, understands marketplaces, and believes in the changes we are seeing in the hardware space. From introductory call to email saying, "I'd like to invest" was about 12 - 18 hours.
How did you fund the project initially? Spend time/money to get a VERY polished pitch deck.
How did you go about finding investors? If an investor says "stay in touch, I'm interested" thats a No.
Did you have to refine or iterate your idea at all in the process? We didn't have to iterate on the site, but I did iterate on the messaging/how I frame what we are doing depending upon the investor, and how that message was received by the last investor. I was constantly iterating what I said from pitch to pitch.
Would you feel that taking a year off to learn python was a worthwhile decision? With no coding background, can I learn it in a year? Definitely - 100% worthwile. I had saved up enough to live for a year without a paycheck (without healthcare...not smart but I did it). If you are interested, go for it. While you still have a job start learning HTML, CSS, some basic things. Give yourself some sort of foundation before taking the plunge. After a year won't be able to get a job as an engineer, but it will definitely help in the long run. I have never regretted that decision.
Any recommendations on resources to learn HTML and CSS? I have some programming skills (C, assembly, VHDL) and found the code academy stuff to be too slow and had a hard time seeing how to really apply it. Link to webdesign.tutsplus.com
I <3 Tuts / Envato.
How much did a year of free time cost you? Rent was $710 a month, Food ~$200-300. Add in taxes & other spending. $20k ish.
There are many exciting developments in hobby-level electronics development. First things like Arduino, now affordable ARM processors. In addition to cheap accelerometers, laser cutting for enclosures, 3d printing, etc. What trends and fads are you seeing that are exciting to you? What kind of products do you think we will see in Tindie next year? Five years from now? Ten? AirPi - Two 17yr olds in London built a shield for Raspberry Pi to turn it into a weather station. Brilliant, cheap product that I never saw coming and has done amazingly. They had to incorporate in the UK, take a loan from their parents, and just shipped hundreds of preorders they got on Tindie. The only thing I know for certain is we will have tens of thousands of hardware companies emerge over the next few years because it is becoming cheaper to prototype and easier to manufacture in lower volumes. Yes "hardware is hard" but it is getting easier and that only opens the door for more people to come in.
Tapster - a robot for manual app testing on mobile devices. EVERY mobile app developer in the world should have one bc of the time you'll save.
How did you come up with the name Tindie? Indie Tech...Tech Indie... Tindie.
The domain was available. Best $7 I've spent.
Amazing site! Just found it. Question/Suggestion ... I'm looking for a site that will accept commissions for one-off projects based on boards like Arduino or Raspberry. Any chance you're site will offer such a market? Thanks! Can you break down "will accept commissions?" Just want to make sure I fully understand what you are looking for.
Hi there. I have been looking into creating a website my self, and I was just curious as to how you build a user base for something like this? How did you get people to sell on Tindie when it first began? Good question - you'll need to figure out where your initial users are and tell them what you are doing. Get people in your corner. As you build the site, give them updates, let them sign up before the site is live. If you don't have enough users on day 1, do more to drive more users to the site. Launch only when you have some amount of users (few hundred or maybe a few thousand is the best case scenario). You'll never be ready to launch but definitely give yourself some momentum before opening the doors.
I did this by keeping everyone on /Arduino in the loop. As I found a name, a domain, logo, I'd share those updates. Sellers were able to sign up and "stock the shelves" prior to launch which meant once I opened the site for transactions, we had ~20 sellers/ products on the site and orders on day 1.
Have you considered reaching out to the Bitcoin mining community? Their hardware seems to fit into your site. We haven't but I'm 100% open to Bitcoin mining products on the site.
Have you considered accepting Bitcoin? We haven't due to its volatility.
Who is your favorite ninja turtle? Easy one - Michelangelo!
Do you plan on taking currencies like bitcoin, megacoin, etc? Not right now. Bitcoin is too volatile. From talking with other marketplaces that implemented Bitcoin, the % of transactions that come through are very, very small. Most people seem to be holding Bitcoins as an investment strategy (the gold analogy). I think that is true. At this point, we can get a much bigger bang for our engineering buck by working on other features vs implementing/maintaing Bitcoin or a similar digital currency.
Why did you decide to go to the valley for this? For someone thinking of starting an e-shop startup, what would you advise? I had been in SF for 4 years, then moved to Portland after the last company I was at was acquired. I moved back bc missed friends and our head of engineering is in Mountain View too. Made sense from a personal perspective.
Would I move to the valley if I didn't already have a connection to the area? I'm not sure. It is definitely cheaper to live somewhere else. However it is more difficult to get into the community from outside the area. If you live in the the valley, you'll constantly hear about startups/tech and meet people who are part of the scene. It's easier to be a part of the conversation if you are in the area.
I've heard from many of my friends in the industry that moving to SF is also a risk as many of the big companies pose a risk at hiring your engineers. Many of them end up moving their companies back to Canada where Engineers are much cheaper for the same quality. Very true. It is very common for people to stay at a job for one year, vest 25% of your options, and leave for the next hot startup. It is valuable to have a presence in the valley - but not necessary for your team to all be there. I'm a huge fan of distributed businesses.
So what's your take on the interest level in hardware overall? Do you think things being sold on the site will continue to increase in complexity? Or will they be limited in scope and cost in the future because people are more interested in the low end of things? Hey Chris! I think it will gain in complexity - esp as parts come down in price, and manufacturing lower quantities becomes more accessible. The opportunities only get magnified as those two trends accelerate.
I think we will always have low level / low end products, but the sky is the limit - in terms of price point and customers. We already have products that cost pennies to $1k+. We will begin to have more consumerish products - but I think those will fuel growth in hardware. The more interesting products emerge, the more interested people will jump into diy. Very cyclical. Arduino & Raspberry Pi just make that first step so much easier. Gateway hardware drugs.
This looks awesome, I'm surprised I've never heard of it. My question: how hard is it really to start your own business and what are some obstacles no one hears about? It is difficult but not impossible. Things to plan for: taxes & attorney fees. You'll want to set up your business correctly if you plan on raising outside investment. If you don't do that right up front, you'll get bit when you fundraise. The legal fees we'll have for this financing round will be over $10k I bet (probably more)
Any suggestions on where to find and learn how to do this hardware stuff? Where did you learn to it? Was there any doubt while creating this project? Did you think about giving up? Google is your best friend. There are books, tutorials, but just dive in. If you have some coding background just get started. Fortunately that is where I started so its more a process of picking something up and playing around (vs starting from 0).
Question: how much equity did you give up for the investment you've gained? Thanks! A this point it is just closing and collecting checks so the final % will be set in a few weeks once we have a definitive amount closed with this round. However the answer you are looking for is 20%-25%.
I have a question. What stage was Tindie in when you pitched to the investors? (users/revenue) What was is about Tindie that made them decide to invest? At this time last year, I forget where we were with users but we had $3600 in sales that month which would be about 100 orders. When talking to early stage investors, it is very much a gamble. The chance of failure much higher, but then again the opportunity is great. I haven't asked them point blank, but I think it ultimately boils down to they have an idea of how the world will work in the future, and you fit in that narrative.
I have a very refined idea for a web/mobile app start up. I have done months of research on the problem/solution I am building but I have no experience designing websites. Thus, I will need to pitch investors to fund development. What are any tips or resources to get in touch with potential investors? Unfortunately you need to get it built. With out a product & traction, it will be very tough sailing
Do you accept Bitcoin and if not can we expect it in the future? We don't right now and don't have any plans to in the future. Copying answer from another question "Bitcoin is too volatile. From talking with other marketplaces that implemented Bitcoin, the % of transactions that come through are very, very small. Most people seem to be holding Bitcoins as an investment strategy (the gold analogy). I think that is true. At this point, we can get a much bigger bang for our engineering buck by working on other features vs implementing/maintaing Bitcoin or a similar digital currency."
I'm an idea guy; I have new ideas everyday and am actually executing a few of them. My roadblock right now is getting it out there and selling it (to consumers, to investors). I have a new idea that, while the product is different than yours, could rope in every business sector. I've never built a business model; all of my stuff is from the idea point of view. I get an idea, find out if it's been done, and then make it work. What can I do to get the word out there and find investors? What kind of cut do you think is fair for investors? Build it. Unfortunately "ideas are cheap." You have to build it before anything else.
We are a startup who has built it (4+ years of work). Its a business administration product. We are in desperate need of sales and marketing department. How do we approach investors? If you are growing like a weed, they should be approaching you (at least some should). Based on the tone of your question, it sounds like that may not be the case?
As a maker who is currently in final stages of getting a product ready (ie 2nd round of PCB prototypes) any advice about how I go about getting it ready to sell on tindie? How do I determine a good initial batch size to order, handle shipping, refunds etc? Good question - once you are ready, you can list it as a Fundraiser (our version of crowfunding which really is just accepting preorders). It has to hit the min # of units sold to 'live' where we bill the orders and you fulfill those ordered. That will give you a good idea of the initial demand. Shipping & handling you'll need to do a little testing on your end bc it depends where you are located & the shipping service you select. Refunds we can handle on our end. You'll just need to tell us which orders to refund. If you have any other questions, feel free to email us at support(at) tindie.com. More than happy to help!
How did you get in front of 50 investors? Thanks for the AMA I kind of see now what I need to do for my Start Up getting rejected 10 times shouldn't be a big deal I guess. 100% from networking. Friend introducing me to someone else, who says you should talk to X. That person sends the intro, and then schedule a meeting. Cold emails don't get you very far with the top investors who are constantly being bombarded with pitches.
This is very interesting. How is the actual pitching process? I mean, once you get introduced, do you pitch to them in a Shark Tank style? over coffee/lunch? And which aspects of Tindie was the biggest seller to the investors? My background.
How did you come up with the idea.
Why now?
What are you doing?
Traction.
Future plans.
The team.
Some were more presentation style with a slideshow and just run through the deck where the investor most likely will interrupt you from time to time with questions on your points/assumptions.
0 were like Shark Tank.
I think the main thing we have going for us is our team -very strong with startup experience at well known companies/ great engineers. Next is our traction and position in the space.
Thanks for the answer! I thought you were a one man team before getting some funding. How did you get a team together when nothing was really proven? Ah at that point it was just myself and I had built everything up until that point. The site was live, we had products, orders, early traction.
of all congrats on the success with your start up and initial funding. What is the number one thing you would say investors look for in a start up? What helped you achieve success while pitching your ideas? Depends ultimately on the investor and if they are the lead or a follow on investor. The lead must believe in the space, have some idea of what is going, and therefore be passionate about the opportunity.
Follow on investors might know something about the space, might not. The one thing I didn't realize is how much they just "pile on." Most investors look for a signal by another big name investor, and if they are investing, looks good and they want in! The pile on mentality is alive and well.
So are you saying that funding is closed and you are not accepting any new investors? Right - the round is closed. The docs are written. The lead investors have already wired their funds. Now just emailing the smaller investors, getting signatures and the wires for their commitments.
1.) What was the toughest question you were asked during pitches? 2.) Any questions worth mentioning a company should be able to answer that they don't think about? 2) I don't think there is any particular question - just think ahead of what they will ask you. Have your questions down cold. Answer & then shut up. Don't be afraid of silence.
3.) Our products are similar in the sense of the needed co-creation so I'm interested in your marketing strategy on both fronts. (finding sellers and finding buyers) 3) Sellers & Customers has been word of mouth. We haven't don't much on the direct marketing side, so I don't have very good advice on that.
4.) I'm sure not everyone has been full time with the company, so how did you manage a team of 5 part-timers and making sure deadlines were met, goals accomplished, etc.? 1) Market size. There isn't a good answer. You can come up with many different answers with many different data points but at the end of the day, no one knows 4) Everyone is full -time.
I'm trying to convince some friends of mine to get serious about taking an idea of there's to an angel to see if they (we) could get funding. So my question is, what did you need to take to investors in the form of demos/research/etc. to get them to take you seriously enough to give you your first (and subsequent) rounds of funding? Build it first. If you get traction on the idea/project, investors will be interested. If it is just an idea, you'll have a very tough time. The only real answer - build it and they will come (if it is a great project and they see potential).
Makers / producers of open source hardware and products? What niche do you feel is currently not being addressed in the open source hardware arena? I think any hardware product today should have an open equivalent. The opportunity is just sitting there for someone to build an open version of X. Open source if a flywheel. Once you get it started and there is a community to support it, it only becomes stronger and better. At the end of the day, I don't see much difference btwn producer vs educator. If you have an open project, part of your job will be education. Just start working on something. At the end of the day, if you want to produce it and sell it you can. If not, no harm/no foul.
Hi Thank you for doing this. My question is, how hard it is to work with VC/Angel people? Do they push you really hard? Good question - some investors you won't get along with. You'll have different ideas/ look at the world differently/ it just isn't a fit. If that is the case, probably not a good fit as a major investor in your company. The can email you rather frequently - don't want to hate that part of your job...
I'm 19 and have no marketable skills beyond being the designated local tech geek. In terms of coding, I could mess around with the variables in JavaScript, but that's about it. Would I have any use in your organization? If not, what would you recommend the first thing I do to set down that path? Unfortunately not. Get more experienced & become a solid JS developer. Build projects, open the code, get feedback, critiqued by the JS community. You'll have a lot of value as a seasoned JS dev (esp as Node picks up traction)
I'd love to hear your thoughts on patents for DIY hardware! Let's say I've got a hardware design idea, but I know it's an evolution of existing technology. How do I go about researching conflicting patents that could prevent me from bringing my idea to market, what steps should I take to differentiate my idea from similar products, and at what point (if any) do I need to see an attorney? I'm anti-patent. It is a huge time/money suck and ultimately hinders innovation. I'm not the best person to ask on researching your design/idea/ etc but I'd probably just go ahead build it and go for it. Any time you spend looking for conflicting patents, someone else will launch their version and get a leg up.
Plans for the international market? Already international! We have customers in over 60 countries, sellers in over 40. I haven't looked lately but those were the numbers about a month or two ago.
Thank you for shipping to India! \o/
Hello Tindie. I am just now incorporating as of January 1st (LLC) with friends in the tech industry for our first start-up. They are all NASA employees and MIT grads with extensive tech background, but my background is in Public Policy and Regulations development. Are there tools on your website for new start ups in the tech field, or could you offer any recommendations as to navigating pitfalls for someone without extensive tech background? We can definitely do a better job on that end. Since you all have an engineering background, most likely the biggest problem will come in execution - sourcing manufacturers, parts, work abroad vs a domestic manufacturer. PM me and we can definitely help!
What has been your biggest regret starting Tindie? No regrets so far. It's been a huge learning experience- esp this year. If I were still at my old job, I'd have been constantly wondering whether or not this could take off. Happy I took the plunge.
HAve you ever thought to add Music Tech to the site? I know a lot of people who are into buying and creating their own midi controllers/instruments. OR have I overlooked something? We have it :) Link to www.tindie.com
How many register sellers and buyers do you have? Sellers: Over 300.

Kinetics - Blockchain, Automation & Energy

PROJECT BLOCKCHAIN VALLEY
My name is Morgan Rockwell, I am CEO of Bitcoin Kinetics Inc. I created the first Bitcoin Operated Service Machine to allow Bitcoin to be used in the real world in all machines & businesses. We are rapidly expanding & growing into new territories, industries and concepts to help build the Bitcoin & Blockchain based industries into a competitive & profitable environment. We have began the process of issuing equity on the NYSE in New York City. We have purchased a new building to house the buildings office & factory. We have made several partnerships with many Bitcoin Business Leaders, Ethereum, Micro-controller & Chip Makers, DIY companies and many more important players in the new technology industries. We now need your help before we are forced to ask help from the banking sector, tyrants or billionaires..
We now need 1000 Bitcoins to create the greatest Bitcoin Business the community will ever see, including the first Bitcoin Town... Ill give you keys to the company, all of the equity, i dont want a dollar. The loan for the purchase of the main street is 1000 BTC for immediate purchase & payback with 15% on the 1000 BTC - giving 1150 BTC payback in 5 years.
Anyone up for that offer? It would be able to change the world if you can contact me & send me that I have contracts ready and waiting.
This is where the future begins.
Along side that move a NEW company is created, to compete with the likes of Google, Apple, GE, Visa & CHASE. It will be called "KINETICS Inc".
Kinetics - Blockchain, Automation & Energy www.Kinetics.cc
KINETICS is facilitator of several Bitcoin & Blockchain projects including:
KINETICS is going to be incorporated in Delaware as a C Corporation. The fully functional business such as #BitcoinKinetics, #BitcoinAcademy & #CoinCanna will be managed, funded and operated by KINETICS Inc.
KINETICS Inc & Bitcoin Kinetics Inc will both be located at our new shop in Upper Lake, CA in Lake County.
9450 Main St, Upper Lake, CA 95485
This buildings rent is $800 per month, to be reduced from $200,000 price for full cash purchase of property. I have plans to purchase the entire building full cash in the next 90 days, until then im moving in 7/13/2014 SUN & paying rent to own for 90 days. I have been told I can purchase the entire block including over 20 different store fronts, garages, a bank, a post office, a saloon, a large antique shop, several window display store front shops and even large areas of land for crypto mining data centers, fields of solar panels & wind generators, as well as the fact that all of California's fresh water is within 2000 yards of the building in several lakes. There is over 100,000 sqft of empty store & office spaces on the main street. All of it has been personally offered to me.
We are commited to partnering with #TeslaMotors to convert the old gas station into a Tesla Super Charger Station equipped with SuperChargers, solar power & a lounge to busy the drivers as they charge their vehicle. We will be creating a Bitcoin ATM friendly lounge where customers can purchase all things Bitcoin, Hardware & even use Bitcoins at all the local shops. Ill be putting www.CryptoCrates.com in one of the shops on the block giving the worlds first Bitcoin Record Store a physical location.
There are now many possibilities with this HUGE opportunity here before us all. We are in talks with #Ethereum and several lenders, venture capitalists, bankers & Bitcoin investors to make this dream of a physical Bitcoin world a reality. We can turn Upper Lake into the start of what will be the home of #BitcoinTOWN, a place where all Bitcoin Business will want to come and have their offices. Eventually growing into a "#BlockchainValley"
There is so much money involved & needed for this long term 100 year plan, In the next 10 years up to 10,000 BTC will be needed to pay:
If you build it, they will come.
There is much to be done, its is all the start of jobs, money & Bitcoins value going to the moon. Building something in the real world with Bitcoins lending technology.
I have over 15 years of construction, civil engineering, electrical engineering & business development. I am the best human on earth to get this mission accomplished and to get the job done. We are in a state ware Bitcoin is now legal tender, the time is NOW. I can make everything happen, i talk well, i don't sleep and work non stop until the goal is reached, i have networked with everyone from the rich to the poor, to the entire Bitcoin community. This is an opportunity to be within 1 1/2 hours of San Francisco and 2 hours from Sacramento. This deal with Tesla Motors gives me the ONLY charging station in this North California region giving the loop from San Francisco, Mendocino, & The i5 to Sacramento a complete loop allowing the Tesla vehicles to travel up into the Forest Area. This will bring HUGE revenue, HUGE partnerships & many many new Bitcoin users and Kinetics customers will all be flocking up from San Francisco to the new land of Bitcoin...
All of you should help us and ill personally make you a very rich Bitcoiner, and you will save the world from fiat, from centralization & from tyranny...
To purchase the main street, we only need 1000 BTC Immediately with 1150 BTC payed back in 5 Years. That is a 15% payback on a 1000 BTC loan. If you can even participate in this loan in fractions, partial or full, please contact us ASAP as moves need to be made immediately. This allows us to acquire the main drag of Main Street, Upper Lake, CA and all of its shops.
We will convert it into a Solar Roadway/SolarCity filled block, with Bitcoin ATMs on every corner, Bitcoin Laundromats, Bitcoin Bank, Bitcoin Friendly Shops, A Blockchain Node in every business, A Tesla Charging Station right in front of the 1920s original Gas Station, a Restaurant Called Satoshi's Grill, with 5 star Chefs already ready to join the team, a record and music shop that takes all crypto currency, The Bitcoin Academy giving a local education center for all to access the newest information, technologies and educators, a Coffee shop friendly to all things Bitcoin & The Blockchain, giving rise to Bitcoin Gift card usage, lounge environment with data center tools. The entire town will have a 4G tower system with the first going behind the Gas Station in the yard & FREE WIFI, LIFI & MESH networking covering the entire area.
We ask you the #Bitcoin Community for funding before we ever ask a Banker, so please help us before we are forced to go ask Goldman Sachs for fiat... The community can gather 1, 10, 100, 1000 or 10000 Bitcoins to make Bitcoin usable in all machines. As a loan of 15% would be very helpful to us and to you in circulating Bitcoin & funding this community venture.
Contact us if you are willing to support this new venture as time is of the essence, moves need to be made NOW, and your Bitcoin's future depends on people like us & you giving Bitcoin real world use. Help us bring the future into the now...
THE BITCOIN TOWN / BLOCKCHAIN VALLEY PLAN
These 10 Phases will take money, people, passion and motivation. Time will only get in the way if you don't become involved with both your Bitcoin, Your Mind, & Your Sweat, Blood & Tears. We will help make this a reality, but first comes capital, participants & the plan. We are all here to help grow into a better world, Bitcoin gives us that last chance for humanity to stand up and shake off its slack. If we can come together and show the world how this technology works in the real world, the planet will see, it will feel, it will hear and know Bitcoin as reality. Over night the world can change if we put out foot down, take a stand, and create the world as we see it to be. People are at war, starving and suffering in the most horrible ways, all I personally can do is fight the good fight with Bitcoin in my hand, there is a chance now for us to have sanctuary and a place to build our plan of attack from. We now have shelter, not just for Kinetics, but for the entire Bitcoin community of users, businesses & investors. You all now will have a safe and friendly place to live, work, shop, learn and grow...
I thank you for your time and your care for the world. Thank You.
