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".

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
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
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Everyday info sec, hardcore info sec, and DNMs

Edit: Currently writing a new version of this, dont know when it will be done.
Edit: Since first post I have updated a few sections with additional information.
I recommend reading it all even if it is very long, I might have placed some relevant info in different sections while thinking about what else needed to be added, plenty of steps remains mostly the same except when I comment directly on it. It is not necessary to do 100% security all the time, unless you absolutely need it, combining some high and some lower security ideas for a balance of security and convenience is useful.
I will base this mostly on Windows, Linux users probably know this, and I have no idea how apple machines work (tho many things in here are still relevant for other operating systems, as they are just general tips)
Disclaimer: There are certainly other steps that can make you more anonymous or safer, however I think for most people this will surfice. Any software I recommend should be independently verified for security, and examples of software are not to be taken as endorsements. I simply use examples and give recommendations when I believe it necessary, or helpful.
I will not really differentiate between anonymity and security, they are often the same thing. As such the word security can mean either more anonymous, less vulnerable, or both.
--------
Everyday Simple Info Sec:
-There could be a hidden administrator user on your PC, make sure to change its password
(Snapchat msgs, reddit dms, discord msgs, are just a few examples of msgs that are never encrypted)
-Any info even send in encrypted msgs (and obviously non encrypted) should still be kept with possible deniability, don't say "I'm gonna do MDMA", say "I'm going out with molly."
-DO NOT STORE ANY PASSWORDS ON GOOGLE, IF GOOGLE LOGIN IS AUTHENTICATED IT WILL AUTFILL ALL PASSWORDS IT HAS SAVED (same with other similar services) (This means if you are logged in to chrome and someone has access to your machine, they can auto fill passwords without entering a single password)
-use a rememberable passphrase, especially for your master key ring aka password manager A long sentence that is memorable makes an okay password (decent example,: "I met my wife at Little Ceasers for the first time on 07/09/20" better even if it's just something you know, if its impersonal, and if you can add special characters or numbers that you won't forget) (A better example for a passphrase is: "There is 0nly 0ne letter that d0esn’t appear in any U.S. state nameQ")
-Purge your internet activity frequently, there's a reason why I only have one post, and a few comments appearing in my account, but thousands of kama. Exposing information needlessly is not good.
-Never post private information publicly, and if you do, do it vaguely as possible. (Example: Not "I'm 15", say "I'm a teenager") Do not post any vital information ever, no birthdays, mother's maiden name, age, or anything you have ever seen in a security question. Never post your current activities while they are ongoing. You going on a vacation? Don't announce it to the world, taking picture there? Post them when you are home.
-Rethink how you do security questions. Many answers to security questions can be found in your internet history. One could use the first word of the security question as an answer, or a different sceme that will mean you always remember it. (Security question need to go, the amount of personal info an average person puts on the internet makes it easy to attack anything using security question)
-------_
High level crimimal information security:
The motto here is, "All the Security, All the Time" As one fuck up can end with you leaving a lick of traceability, and you could be fucked.
Pre Note: All of your software should always be up to date. Also even perfect info sec does not guarantee you are completely safe, a new zero day (exploit) can still fuck you, but good info security makes you significantly safer, by eliminating as many attacks as possible.
-Get a new device (or make a already owned device seem like you never owned it, do this only if you know how to, there's a lot of stuff that goes into that, like changing your mac adress etc) buy with cash, and your face covered, preferably far away from where you live. (Do I need to specify to not bring your phone or anything else that tracks your location to anywhere you want to go anonymously?) (Be aware that even hardware can have vulnerabilities, many cpus have known vulnerabilities, I can't list them all, do some research before buying)
-If you know how to use Tails (A linux distro designed for Info sec) use that, preferably on a USB. (Or learn how to use tails, its better, but complicated) Otherwise a clean copy of windows (make sure its not in any way associated with you) can do the job too, tho not as well. (Using a VM might give extra security, since VMs usually erase all data and RAM they were using on shutdown)
-Get a non tracking VPN, Enable the kill switch (a setting that disables all traffic that doesn't go through the VPN) (change your firewall settings to only allow the traffic from the VPN, windows guide (Change settings so only traffic from the tor application is send) Edit: (Due to complaints: do not use vpn over tor, use tor over vpn. tor over vpn has no notable downside, if the VPN logs it makes no difference, your ISP will always log anyways, and vpns remove other attack vectors and also provide backup security should tor fail. Again even if the VPN tracks you only change the people doing the tracking, but now you are further removed making it more anonymous and also with less vulnerabilities)
-rember privacy settings, cookie cleaner, and antivirus, password (There could be a hidden administrator user on your PC, make sure to change its password)
-Always use the device on a non admin account
-Ideally use this device only on networks that are not connected with you. Such as public networks (try to never use the same public networks twice, move around) (a home network should be fine now, as it should never be exposed, but more security is always better) (Its just a conveniences vs security trade)
-Never use accounts that have been exposed to lower security on higher security machines
-your browser is now TOR (or your preferred security focused browser, if you dont plan on using onion ) Make sure you get the standalone version of tor not the addon build (the standalone is safer, because there are less settings and options to tweak)
-Change your tor settings, to safest mode, enable a bridge (to my knowledge there's no difference in security between the build in bridges in tor), enable automatic updates, set duckduckgo onion as your primary browser. Set dark.fail onion page as your home page. (Or your preferred privacy search engine and onion directory)
-------_
How to use dark net markets (DNMs)
If you finished your High Security setup, we can dive right in. Otherwise go do that. This is where all that is essential.
Quick info on Tor, and onion sites. There is no search engine. It's all based of directories and addresses you are given by others. Tor will likely not be very quick, it has to pass through multiple networks to get to the destination. DNMs sometimes exit scam, an exit scam is when a market shuts down completely and takes all the money, this is a risk when using DNMs, it's not too common but happens maybe 0-4 times a year. The admins of thoese servers need to get out at some point, before they get jailed, so they exit the game, and scam everyone out of their money.
-A very useful onion directory is dark.fail it has a lot of links, for all kinds of stuff. News, email, DNMs, Psychonautwiki (harm reduction website), forums etc. (Other directories also exist)
-Pick a market, preferably one that handles secure connection server side instead of requiring you to establish the secure connection. Then create an account. Your account once created should include an entry box in your profile for a pgp key, post your PUBLIC key in there. (Verify the link is not a scam, most markets should provide a pgp signature)
-Next is currency setup. All major cryptocurrency exchangers can be used, I can recommend coin base but there could be better ones out there. Unless you find a small non U.S., exchange, they will always ask for your identity. So unless you can find a trustworthy exchange that doesn't ID, you will need to give it to them. (Side note, all major crypto exchangers report to the IRS, if the IRS asks you if you bought cryptocurrency and you bought while having IDed yourself SAY YES, DO NOT COMMIT TAX FRAUD WHEN THEY KNOW YOU DID)
-Transfer (monero you can send directly, btc you should scramble) to your wallet. There are two options a cold wallet (physical) or a software wallet. Software wallets usually dont cost anything so I recommend them, even if often less safe. Electrum is easy to use, and pretty safe. You can also do your own research and find a wallet that fits your needs.
-now you are ready to buy, only buy using escrow (it means the money is held by the market as a middle man until the product is delivered, they will also handle any issues like wrong quantity, cuts, etc), judge the reviews for a product, and if available look at the history of the vendor, until you find a product from a vendor you trust. (I recommend to buy within your country as much as possible, so it doesn't go through customs, it's very rare that something is found, but it can happen)
-now you get to buy, depending on market, you either have cryptocurrency stored in their wallets (not recommend, you will lose it in an exit scam) or you can send it every order. When you send your delivery adress (or the one you want it to go to) encrypt the adress using the sellers public key. Make sure the adress is correct.
-wait for the product, make sure to extend the escrow until the product arrives, if you can't extend it anymore dispute the order, and a moderator will step in
-test the product, use it, and leave a review. PLEASE LEAVE A REVIEW, DNMs only work because of reviews.
Edit: Didn't imagine I would write over 15000 words. Oh well, it was fun. Hope it helps, if you have any questions feel free to ask.
No idea how long this will stay up, I might purge it in 7 days, or never.

Was I phished.. Or? After downloading newest Electrum from official site.. help please!

Hello!
Earlier today, before purchasing BTC online, I updated my electrum by downloading the newest version (4.0.3) from the official site (electrum.org - which was also the first result on Bing).
When I clicked the "copy to clipboard" button for my receiving address, I noticed the address copied to my clipboard was different than the one displayed. I tried this a few different times with several different addresses with the same result. I figured that perhaps the address being displayed (not the one that was being copied to my clipboard) was perhaps just a bug or some sort of error, and that the address being copied to my clipboard HAD to be my address since it was coming from my wallet. But maybe I was wrong..
I proceeded to withdrawal the bitcoin from the site I purchased from, having the coin sent to the address that was being copied to my clipboard. Except this time, I didn't notice any coins being sent to my electrum wallet.
I opened Electrum and under the addresses tab, searched for the address that was being copied to my clipboard via the "copy to clipboard" button I used under receiving addresses as previously mentioned, however there was no sign of the address in the addresses tab. And each time I would click the "copy to clipboard" button for receiving addresses, it would give me another address that was not listed under my addresses tab.
This happened hours ago and I'm not sure what to do at this point. I'm not sure if I've somehow been phished, even using the official website, or if there's something I'm missing/overlooked. Whatever the case, I cant afford to lose the amount of money lost.
If anyone could please help shed some light on the situation, I would very much appreciate any insight you may have to offer. I'm at a complete loss at this point. Is there anything I can do? Am I missing something here? Or... am I totally screwed? Thank you for your time.

Checking for btc sending address. Help.

I re-installed electrum after a long time and reloaded my old wallet. As i wanted to check on a purchase transaction from a few years ago.
I clicked on it and it provided details i do not understand.
How do i find out the sending address? What is the btc address my btc was deducted from to make the payment.
Thanks.
Edit: when i search the transaction id with various block chain explorers, it lists as input/output or sendereceiver sometimes. And my bitcoin address is there. I think that shd be it?

What I currently use for privacy

So this is what software I currently use for privacy, would like some opinions if possible:
Starting with my cellphone, my device is a Google Pixel 3A XL with GrapheneOS flashed, I have the following apps installed:
F-Droid and AuroraOSS (as my app stores), NewPipe (youtube client), Vanadium (web browser), Tutanota and K-9 Mail (for e-mails), OsmAnd+ (for maps), Joplin (notes), Open Camera (camera), OpenBoard and Mozc for Android (Keyboard and Japanese Keyboard), Aegis Authenticator, KeePassDX (password manager), LibreTorrent (torrent client), Librera PRO (pdf/epub/mobi reader, I don't own a Kindle nor want to own one so I use my cellphone to read), Tachiyomi (manga reader), Signal (for messaging), Vinyl Music Player, VLC, Simple Gallery Pro and Simple Calendar Pro (I prefer them over stock Graphene options) and I also use Electrum and Samourai (Bitcoin Wallet) and Monerujo (Monero Wallet)
I also have OpenVPN (for VPN) and use a private DNS for ad and tracking blocking (provided by my VPN provider)
I have 3-4 PCs, will go over every single one of them:
my main PC is a desktop PC (that I built myself) that I mainly use for working and other tasks.
It runs Artix Linux (basically Arch Linux without systemd), I use UFW as my firewall (denying all incoming and also denying all outgoing only allowing what is useful) and I also use AppArmor Profiles, I disabled IPV6 and SWAP, configured my VPN connection as well on network settings and I currently run OpenVPN on my computer (my VPN provider allows for multi-hop cascade through OpenVPN in which I can create a custom VPN cascade up to four servers, each consecutive hop re-encrypts my traffic and assigns me a new IP address) and I've also set disk encryption on installation (have set in all of my computers)
As for software: I use Mozilla Firefox as my web browser (I set it to always be in private mode, unchecked suggestions for browsing history, bookmarks, and open tabs, I've also disabled the Firefox data collection in settings and block dangerous and deceptive content, I use DuckDuckGo as my search engine, I use Firefox Home as my default as my homepage. The rest of my tweaks were done in about:config (using privacytools.io site tweaks + geo.enabled = false, network.cookie.lifetimePolicy = 2 and dom.security.https_only_mode as true which are not listed on the site) and the only addons I use are uBlock Origin on Hard Mode and Decentraleyes), KeePassXC (password manager), VIM (use it as a Text Editor and as an IDE for coding), LibreOffice (for working stuff), GIMP (image editor), VLC, qBitTorrent and Tutanota's Desktop Client and Thunderbird (for e-mails)
I also use KVM/QEMU for virtual machines (usually in case I wanna test some distro or use Tails/Whonix)
For my gaming PC (also a desktop I've built myself) I run Manjaro KDE on it, the only apps I have in the system are Firefox (same settings as above), OBS and KVM/QEMU (which I use a Win10 virtual machine for games, there are tutorials on YouTube on how to do so if you're interested). I have the same firewall settings as above, using AppArmor as well and I've also disabled IPV6 and SWAP, I run OpenVPN on it as well as my VPN DNS settings on network settings. I also use different mouse and keyboard on both my PCs and never mix them together.
My other 2 PCs are both laptops, one is a Acer Aspire Nitro I've bought for work (in case I need to work while in a trip or if I wanna work outside etc), it has the same settings and programs as my main PC but I run Gentoo on it. The other laptop is an old ThinkPad that runs Slackware on it, but I rarely use it and this laptop is most of the times not with me for safety reasons.
For some other devices and stuff: I have an Asus RT-AC86U router with OpenWRT flashed on it that I also run OpenVPN config files (this one coming from another provider, I use two VPN providers, on in my PCs and the other in my router), I have a Ledger Nano S as a hardware wallet for both Bitcoin and Monero (most of my cryptocurrency is there, I use hardware wallet for hodling purposes and as my emergency funding) and I have LOTS of USB flash drivers (all of them for Linux Live ISOs purposes), I also have a Nintendo Switch Lite (only gaming console I have, although have not been playing that much on it recently) that I only connect to the internet in case I need to download some updates or play online and after I'm done I immediately disconnect it from the internet.
Some other privacy habits I have are:
I don't own any smart device like Smart TVs (I've been more than 10 years now without watching TV, doesn't even bother me), Smart Fridges or Dishwashers that connect to your internet, ROOMBAS, Smart Home etc, I keep all my money on crypto (and I have a small amount in gold as well, but I rarely invest on it, all my gold is stored in a manual safe here in my apartment) and I only have like, 10 bucks or so in my back account (as soon as I receive any money I just left the necessary in my account to pay bills and put all the rest on crypto, I try to pay everything on crypto or cash), I RARELY use cloud storage, but if I need to, I go with NextCloud and encrypt all my files with VeraCrypt before uploading it, all my VPN services were paid with Bitcoin (I try to pay everything with crypto as previously said) and I never write directly into any website, I usually write my text on a text editor, copy it and paste it on the website (needless to say that I don't use mainstream social media as well)
So, what do you guys think? anything that you would add your recommend me? (before anyone mentions about self-hosting a DNS server using Pi-hole on a Raspberry Pi, I'm actually thinking on doing it in a near future)
EDIT: forgot to mention that I don't watch YouTube on PC on youtube site, I mostly watch youtube's videos on invidio.us and only use the youtube site for watching live streams honestly. And I also barely go outside with my smartphone (only if I really need to) and I usually keep it away from my computers etc.
EDIT 2: also another thing: I covered all my laptop's webcams with black electrical tape, I have a Logitech C922 Pro webcam for my desktop PCs but rarely use it, and when I need to use it, I unplug it as soon as I'm done with it.

How to Store Your Bitcoin

Before holding any bitcoin, you need somewhere to store it. Just like in the physical world, you store your bitcoin in a wallet.
Similar to a bank account number, your wallet comes with a wallet address that shows up in a ledger search and is shared with others so you can make transactions. This address, which is a shorter, more usable version of your public key, consists of between 26 and 35 random alphanumeric characters, something like 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa. Keep in mind that every letter and number in that address is important. Before sending any bitcoin to your wallet, double-check the entire address, character by character.
Also tied to your wallet address is one or more private keys, which as the name suggests should not be shared with anyone. Keys are used to verify you own the aforementioned public key, and to sign off on transactions. Some wallets create a secure seed phrase, a set of words that will allow you to unlock your wallet if you lose your keys. Print this phrase out and keep it in a safe place.
The unfortunate truth is your bitcoin wallet is akin to your physical wallet. If you lose the private keys to your wallet, you’re most likely going to lose the currency in it forever.
Your wallet generates a master file where your public and private keys are stored. This file should be backed up in case the original file is lost or damaged. Otherwise, you risk losing access to your funds.
You can store your private keys on your computer, mobile device, on a physical storage gadget or even on a piece of paper. It’s crucial that you keep your private keys safe by generating backups both online and offline.
Remember: Your wallet does not reside on any single device. The wallet itself resides on the Bitcoin blockchain, just as your banking app doesn’t truly “hold” the cash in your checking account.
While wallet apps work well and are relatively safe, the safest option is a hardware wallet you keep offline, in a secure place. The most popular hardware wallets use special layers of security to ensure your keys are not stolen and your bitcoin is safe. But, once again, if you lose the hardware wallet your bitcoins are gone unless you have kept reliable backups of the keys.
The least-secure option is an online wallet, i.e. storing your bitcoin in an exchange. This is because the keys are held by a third party. For many, the online exchange wallets are the easiest to set up and use, presenting an all-too-familiar choice: convenience versus safety.
Many serious bitcoin investors use a hybrid approach: They hold a core, long-term amount of bitcoin offline in so-called “cold storage,” while keeping a spending balance in a mobile account.
Depending on your bitcoin strategy and willingness to get technical, here are the different types of bitcoin wallets available. Bitcoin.org has a helper that will show you which wallet to choose.
Cloud wallets exist online and the keys are usually stored in a distant server run by a third party. Cloud-based wallets tend to have a more user-friendly interface but you will be trusting a third party with your private keys, which makes your funds more susceptible to theft. Some examples of this wallet type are Coinbase, Blockchain and Lumi Wallet. Most cryptocurrencies, including bitcoin, have their own native wallets. Some offer additional security features such as offline storage (Coinbase and Xapo).
With your private keys stored on a server, you have to trust the host’s security measures and also trust the host won’t disappear with your money or close down and deny you access.
Software wallets can be installed directly on your computer, giving you private control of your keys. Most have relatively easy configuration and are free. The disadvantage is you are in charge of securing your keys. Software wallets also require greater security precautions. If your computer is hacked or stolen, the thief can get a copy of your wallet and your bitcoin.
While you can download the original software Bitcoin Core protocol (which stores a ledger of all transactions since 2009 and takes up a lot of space), most wallets in use today are “light” wallets, or SPV (Simplified Payment Verification) wallets, which do not download the entire ledger but sync to it.
Electrum is a well-known SPV desktop bitcoin wallet that also offers “cold storage” (a totally offline option for additional security). Exodus can track multiple assets with a sophisticated user interface. Some (such as Jaxx Liberty) can hold a wide range of digital assets, and some (such as Copay) offer the possibility of shared accounts.
Before downloading any app, please confirm you are downloading a legitimate copy of a real wallet. Some shady programmers create clones of various crypto websites and offer downloads for free, leading to the possibility of a hack.
Mobile wallets are available as apps for your smartphone, especially useful if you want to pay for something in bitcoin in a shop or if you want to buy, sell or send while on the move. All of the online wallets and most of the desktop ones mentioned above have mobile versions, while others – such as Abra, Edge and Bread – were created with mobile in mind. Remember, many online wallets will store your keys on the phone itself, leading to the possibility of losing your bitcoin if you lose your phone. Always keep a backup of your keys on a different device and print out your seed phrase.
Hardware wallets are small devices that connect to the web only to enact bitcoin transactions. They are more secure because they are generally offline and therefore not hackable. They can be stolen or lost, however, along with the bitcoins that belong to the stored private keys, so it’s recommended that you backup your keys. Some large investors keep their hardware wallets in secure locations such as bank vaults. Trezor, Keepkey and Ledger are notable examples.
Paper wallets are perhaps the simplest of all the wallets. Paper wallets are pieces of paper that contain the private and public keys of a bitcoin address. Ideal for the long-term storage of bitcoin (away from fire and water, of course) or for the giving of bitcoin as a gift, these wallets are more secure in that they’re not connected to a network. They are, however, easier to lose.
With services such as WalletGenerator, you can easily create a new address and print the wallet on your printer. When you’re ready to top up your paper wallet you simply send some bitcoin to that address and then store it safely. Whatever option you go for, be sure to back up everything and only tell your nearest and dearest where your backups are stored.

How to add https in btc-rpc-explorer?

Hi everyone, I installed btc-rpc-explorer on my Linux, it's working and whoever had the idea of ​​carrying out and maintaining this project is to be congratulated!
However, when accessing the address (localhost: 3002) there is no https that allows an encrypted and secure connection. Is there any way to do that? Remembering that I am totally about internet protocols, but if someone explains it right I will surely learn.
The other question I have is about browsing bitcoin addresses on btc-rpc-explorer, it is not possible to search for addresses, only TXs, when I click on an address it shows only basic information and QR code, but it does not show the transactions that happened on that Address
When I click on the address it says that I must configure an address API like an Electrum Server ... Does anyone who has managed to do this know to inform me if it is easy?

How To Stake/Mine Coinevo

EVO Staking/Evo mining

Evo uses Proof of Stake consensus mechanism, which is different from Bitcoin's PoW (Proof of Work). Evo mining process in PoS system is called staking. The block producer will get 6.5EVO, as well as the transaction fees and gases as block reward. So the real reward is usually more than 6.5 evo in total.
Basic requirements for staking:
  1. Run a Coinevo fullnode, and keep online (Since Coinevo is using PoS, we don't need any mining machine, just PC or even Raspberry Pi can run a fullnode);
  2. Have some EVO in the wallet (fullnode)(Any amount of EVO can be used for staking, more EVO means higher possibility to stake).
If you have no EVO yet, please get some from market before you doing following staking settings.
Currently, Coinevo Core wallet is the only wallet that support Coinevo PoS staking. Note that other wallets like mobile wallet and Evo Electrum are not able to stake for the time being.
Two ways to stake:
Either way works in the same way for staking, so you can choose either method you like.

Method 1:Staking with evod (command line)

1. Run evod

Follow the guidance to run evod :
./evod -daemon 
Staking is default on for evod, so no need for other options if you only want to stake.

2. Send some EVO to your wallet

First you can generate a new address with:
./evo-cli getnewaddress 
This will generate a new address with Prefix '1'. You can send some EVO to this new generated address for staking. You can generate as many addresses as you like, and send arbitrary EVO as you like for staking.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..
After the EVO node syncing to the latest block, you can check current balance with ./evo-cli getbalance or get utxo list with./evo-cli listunspent
Please do following steps after your coin is mature.

3. Check staking info

Check current staking info with:
./evo-cli getstakinginfo 
You might get the result like this:
{ "enabled": true, "staking": true, "errors": "", "currentblocktx": 0, "pooledtx": 0, "difficulty": 3693409.779133397, "search-interval": 1577, "weight": 309584575558555, "netstakeweight": 1948540143266404, "expectedtime": 805 } 
enabled means if your wallet have enabled staking, it should be true by default. staking means if your wallet is currently staking (mining). weight stands for the amount of EVO that is staking right now, with unit 10^-8EVO, here in the example, we have 0.532EVO staking. expectedtime stands for the expected time that you will get a reward, the unit is second.

4. How to stake if the wallet is encrypted?

If your wallet is not encrypted, you can skip this section. However, for security, we recommand you encrypt your wallet.
Coinevo wallet can be encrypted with encryptwallet . However, staking will be stopped when it is encrypted. For example, ./evo-cli getstakinginfo for a encrypted wallet:
{ "enabled": true, "staking": false, "errors": "", "currentblocksize": 1000, "currentblocktx": 0, "pooledtx": 94, "difficulty": 5788429.670171153, "search-interval": 0, "weight": 53206430, "netstakeweight": 2438496688951881, "expectedtime": 0 } 
See staking turns to false , which means wallet is not staking.
You can use walletpassphrase to unlock wallet for staking:
./evo-cli walletpassphrase "" 99999999 true 
After unlocking, you can double check getstakinginfo , it should look the same with previous unlocked result, staking become true.

Method 2: Staking with evo-qt wallet (official PC wallet)

Current supported platform: Mac/Linux/Windows.

1. Open Evo qt wallet

Launch the wallet.

2. Send some EVO to your wallet

If you already have some EVO in your wallet, you might skip this step.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..

3. Check staking status

The flash sign at the bottom of wallet shows staking info :
Solid black flash means it is staking now. For more information, you can put your mouse on the flash, e.g.:
Hollow flash measn it is not staking
Possible reasons for not staking:
No flash sign means staking is disabled

About block reward

The block producer will get more than 6.5 EVO rewards, something to keep in mind:

How to disable staking?

Staking is by default enabled for Coinevo wallet. If you need to disable staking for some reason (for example exchanges are always recommanded to disable staking), you might following anyone of the 3 ways below:
1 Add -staking=false when running Coinevo node:
./evod -staking=false -daemon 
For qt wallet, it is like:
./evo-qt -staking=false 
2 Add config staking=false in evo.conf;
3 Encrypt wallet, since encrypted wallet will automatically stop staking.

Confused about anonymity

(I apologize for the noob question, but couldn't find the answer searching the sub.)
Let's say I buy from an exchange that has my personal info, then transfer that to an Electrum wallet, then transfer it again to an Electrum wallet on Tor&Tails to make a transaction.
1.) Can that transaction be traced back to me?
2.) If no, can transactions eventually be traced back to me if I use this same pathway, but with different wallet addresses?
3.) If yes, have all these wallets become essentially outed as "mine" and compromised for anonymous bitcoin transactions in the future? (If yes, is there a way of anonymizing the coins in those wallets?)
4.) Can bitcoin mixers help me in this process going forward?
Thanks!

FinderOuter: the bitcoin recovery tool

Link: https://github.com/Coding-Enthusiast/FinderOuter
The FinderOuter is a bitcoin recovery tool that focuses on making the recovery process easy for everyone. There is no need to read long guide pages to learn how to use the application. Instead it will always be as easy as filling some boxes, maybe selecting some options and clicking a button all in a user-friendly GUI. Each recovery option is written from scratch and all parts down to the basic cryptography used (such as SHA, ECC,...) are specialized for maximum efficiency.

Available options

1. Message signature verification

User can enter a message signature here to verify it. In case there is a problem with the message (except being an actually invalid signature), the code can search to find the common issues that some signing tools have and fix them.

2. Missing Base-58 characters

This option helps recover any base-58 encoded string with a checksum that is missing some characters. For example a damaged paper wallet where some characters are erased/unreadable. The position of missing characters must be known. It works for (1) WIFs (Base-58 encoded private key) (2) Addresses (Base-58 encoded P2PKH address) (3) BIP-38 (Base-58 encoded encrypted private key).
There is also a "special case" where a compressed private key is missing 3 characters at unknown positions.

3. Missing Base-16 characters

This option is similar to previous feature but works for base-16 (hexadecimal) private keys. It currently requires an address and only checks compressed public keys. Unlike the other options, this one is very slow since it depends on ECC and that is not yet optimized.

4. Missing mini-privatekey characters

This option is similar to 2 and 3 but works for mini-privatekeys (eg. SzavMBLoXU6kDrqtUVmffv). It requires an address to check each possible key against, as a result it is also slower since it depends on ECC and has 2 additional hashes.

5. Missing mnomonic (seed) words

This option works for BIP-39 mnemonics (others like Electrum will be added in the future) that have some words missing. It requires knowing one child key or address created from that seed and the exact path of it.

Future plans

[Idea] Bech32 encoding of private keys

Ever since I saw BIP-173 I was excited to see the encoding used anywhere other than addresses. I've done some search but apart from some comments here and there I haven't been able to find any major work done (please let me know if you know of any proposals). Here is my idea of addressing some of the problems with current encoding of private keys:

Using Bech32 encoding instead of Base58

While writing a private key recovery tool I've felt how hard it is to come up with an optimized algorithm to recover a key that is missing a couple of characters (eg. a damaged paper wallet). That is not true with Bech32 being a multiply of base-2 algorithm is inherently faster, and the checksum is not a bottleneck since it is not a hash algorithm. Bech32 also has the benefit of having error detection.

Script (address) type

Currently when a user imports/sweeps a private key in a wallet client, that client either has to explicitly ask user for the script type (like Electrum) which means user is exposed to complications and has to be familiar with script types; or the wallet has to construct all script types and scan the blockchain for all of them (like bitcoin core) which adds more burden on the client. If the encoding included a script type that becomes so much easier.

Locktime!

Another burden on both clients and users (specially full node users) is the time consuming need for a re-scan of the entire blockchain to find the historical transactions that belong to an imported key. A timestamp can make that process a lot shorter. Using locktime (similar to last 4 bytes of any transaction) the key string (aka WIF) could include either a block height or a date-time value of when the key was created.
This idea was added to Bitcoin.Net library as an "experimental" class. Direct link to the code
Here is an example with a random key from Bitcoin.Net KeyHelper class:
Original WIF (Base-58): L28Peud5cQcijrtMthAdUS8FynpM8PKZtnoUZb1VAio9WxKoebHt Key bytes (Base-16): 92734fe879f662ff8ee4eb87dd019425e2ee73ff3edd0c4dc3def2f71e1a6a69 Version byte (ie. the script type): 0x02 or P2WPKH Date UTC: 5/4/2020 7:11:05 AM H.R.P.: bprv New encoding (versioned Bech-32): bprv1zjfe5l6re7e30lrhyawra6qv5yh3wuull8mwscnwrmme0w8s6df5sns90tcqqzyen4e 
Note that key is encoded the same way an address would be encoded (version byte is added separately as a 5-bit value instead of 8-bit).

Lost electrum seed key.

So basically i got this problem and im new to BTC. I downloaded electrum and bitcoin core yesterday. Created electrum vallet that is imported, watching only and a friend of mine sent money to my address. Now i searched around and found out that i can't send btc to others if its watching only. Then i found out i needed seed that i didnt write down when created this acc. Anyone can help me with making it from imported watching only to standart vallet without seed? I got the password and the vallet opened on my pc but i don't know how to fix the problem.

Electrum wallet file?

Hi someone sent me a electrum seed file but is this useful? I can only view the file as text and see some bitcoin addresses. Because when I search electrum it says it only restore using passphrase?

Electrum: No inputs found (note that inputs need to be confirmed)

Hi all, I thought I considered myself an intermediate bitcoiner, but this is making me doubt. I'm testing cold storage and running into serious issues.
Here's what's happening.
I generated public/private keys on bitaddress.org. I sent a small transaction, verified here: https://www.blockchain.com/btc/address/1GALcB4xEM9H8r6W6iz6XrrEYLLGZ8w1Xg
I then opened Electrum (which I also have successfully sent a small amount of btc), and attempted to "sweep private keys." I took the corresponding private key of the transaction's address above, and got the error as listed in the title.
I searched this history of bitcoin and saw a solution, as described here: https://bitzuma.com/posts/how-to-sweep-your-bitcoin-core-wallet-into-electrum/
So I tried the prefix before sweeping, same result (see post title).
What is happening? How do I sweep this small balance on cold storage into Electrum? (edit: spell)

Help: I think I just had BSV stolen from me while using ElectrumSV

EDIT: NOTHING WAS STOLEN! ElectrumSV and BSV in general are perfectly fine (and have a great community). The problem is my understanding of replay protection.
The problem occurred because I had restored an old Electrum Bitcoin wallet to Electron Cash a day or two ago to transfer the funds to Coinbase to consolidate them. They were confirmed in the account, so I figured the wallet now had nothing to do with BCH any longer. Then last night, I restored the same seed to ElectrumSV and transferred some of these BSV funds to a wallet at another exchange as well as a separate local wallet.
I won't pretend that I completely understand it yet, but somehow replay protection between the two blockchains messed up the BSV transfers. The part that I still don't understand is how a confirmed BCH transaction from a day before could affect transactions on the BSV blockchain a day later. I'd love an explanation of how that works, but I'm going to be doing some heavy research on it tomorrow.
Thanks to everyone who replied and helped troubleshoot in this thread, but especially u/Deminero30 for taking almost three hours to work with me to sort this out.
Yesterday I decided to move my BSV out of an old wallet I had, so I downloaded the Windows version of the ElectrumSV wallet from https://electrumsv.io/ and imported a pre-split BCH wallet into it.
When I went to send a test amount to another address, I got an error from the client that
"Your transaction was not sent: it conflicts with one already in the server's mempool".
The error apparently relayed from the server was
"'the transaction was rejected by network rules\n\n258: txn-mempool-conflict..."
I tried sending the same transaction again, but got the same error. The transaction didn't show up in ElectrumSV, and didn't show up in a search on two block explorers.
At the time I figured it was a problem with my PC, network congestion, or too low of a fee, so I worked on it for a while and then tried again later. I upped the sats/byte to 2, and then created a new transaction spending from a different wallet. This one went through, so I figured nothing was wrong.
Then I sent a few more test transactions, a couple of which went through. Then there were two larger ones that got the same error as before. I wasn't too worried becuase I thought they would just clear from the mempool at some point.
But then I saw that the transaction from last night showed up in my wallet and on the block explorer, but it was sent to an address I'd never seen before! This is when I got more worried about what was going on.
I looked up the transaction on Blockchair, and I saw that the transaction ID showed up not just on the BSV chain, but also on the Bitcoin Cash chain with different addresses but the same amounts! This is extra strange because I had extracted all of the BCH from the wallet a while back.
Since then I saw one more of these transactions that had errored out initially get confirmed with a different address that isn't mine. The transaction ID is the same between the two chains as well. Also, I had upped the fee to 2 sats/byte, but this transaction had just 1 sat/byte. So it definitely wasn't the one I initially broadcast.
At this point I'm convinced that either ElectrumSV or one of the servers is hacked somehow. I don't understand any other way this could have happened.
I looked at https://ccoin.cash as suggested by u/deminero30 in another thread to try to double-spend the ones that aren't gone yet, but I haven't been able to figure it out yet (and no, I haven't and wouldn't upload a private key to a website; I'd do it offline).
I would really appreciate it if someone could tell me what's going on here. I really hope that I'm just making some stupid mistake, but I realize that the BSV that are gone aren't likely to come back. I also have at least one transaction that errored and hasn't been confirmed yet, so I'd love to know if there's any way to cancel what's out there in the mempool.
The first transaction is this one: [removed]
Thank you

What to do?

Ok I'm total noob in this. So someone in telegram sent me this 2 file. It says electrum old and new wallet. New one is kb sized and the old one is 3.5 mb. When I view it as text and I can see many bitcoin addresses in it. Upon searching about electrum I found that it uses passphrase. What is this file actually? Is this useless without the passphrase?

How long does it take to send bitcoin from Coinbase?
The bitcoin transfer takes only two-minutes., but sometimes it is as late as hours after your transfer. The delay happens because you will need to be verified by miners, and also it depends upon the speed of the network, this could be either a slow or fast process.
Wallets like Electrum only request one confirmation, which is much faster than using an exchange like Kraken, which will require six confirmations.
When a Bitcoin transaction is sent out, it has to wait until it is ready to be verified by a miner. Once it is ready for verification and has been shown on the network, it will receive one confirmation.
Each new transaction added to the network will add another confirmation to yours and some platforms prefer waiting for additional confirmations to make sure that everything is correct before they add your funds to your wallet.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

/r/Bitcoin FAQ - Newcomers 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.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer.

Bank Transfer Credit / Debit card Cash
Coinbase Coinbase LocalBitcoins
Gemini Bitstamp LibertyX
GDAX Bitit Mycelium LocalTrader
Bitstamp Cex.io BitQuick
Kraken CoinMama WallofCoins
Xapo BitcoinOTC
Cex.io
itBit
Bitit
Bitsquare
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or 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.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
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, usually from a text message or app, 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.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:
