/r/Bitcoin FAQ – Newcomers please read

Welcome to the /r/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 lots of additional video resources check out the videos wiki page or /r/BitcoinTV.

Key properties of bitcoin

  • Limited Supply (there will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here)
  • Open source (You can read the source code yourself here)
  • Decentralized (Bitcoin is globally distributed across thousands of nodes and as such can't be shut down similar to how Bittorrent works)
  • Permissionless (No one can prevent you from interacting with the bitcoin network of your own free will, even in areas currently unserved by traditional banking. This makes it a truly global payment platform)
  • Censorship resistant (No one can censor or block transactions that they disagree with, see Operation Chokepoint)
  • Push system (there are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them)
  • Designed to fit all the fundamental properties of money better than gold or fiat

Additional Bitcoin statistics can be found here. Developer resources can be found here and here. Peer-reviewed research papers can be found here and here. And of course, the whitepaper that started it all 🙂

Where can I buy bitcoins?

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. Some of the more popular resources are below, more can be found here.

Here is a listing of local ATMs. Also, Lawnmower is also a handy way to make small recurring purchases of bitcoin. If you would like your paycheck auotmatically 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. Here are a couple useful sites (bitkoin.io, preev.com) 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.

  • If you prefer to "be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you prefer easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor, Ledger, Case Wallet, or KeepKey is recommended. A more advanced option is to secure them yourself using paper wallets generated offline.

  • If you prefer to let bitcoin banks manage your coins, try Coinbase or Circle but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.

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.

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 /r/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. You can view the global node distribution here.

Earning bitcoins

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:

  • 0.02 BTC
  • 20 mBTC
  • 20,000 bits

For more information check out the Bitcoin units wiki.
