Getting my first coins

The German Bitcoin market place offers 0.01 BTC for every new registered user. The Bitcoin Faucet website currently hands out 0.001 BTC to new bitcoin users. Fill in the form with your bitcoin address. Bit by Bit is another website which provides.001 BTC for free and can be used daily. It also offers weekly lottery drawings for beginners. When you wish to add more, view Buying bitcoins.

Getting free coins from the Faucet

A new entry should appear in Bitcoin. The network hasn't yet confirmed it, but you know it's being processed. After about one hour it should get 6 confirmations. You are able to spend the coins when there is only one confirmation.

The confirmation counter (like the block counter) will increase by one roughly every 10 minutes. Six confirmations are considered as 100% sure a transfer has been processed.

Buying Bitcoins

Bitcoins can be bought from individuals, on trading exchanges or from other online services. See the main page about Buying Bitcoins for more information.

Points to remember

  • You don't need to be online to receive BTC.
  • You can create as many new addresses as you like. Using a different address each time helps keep you anonymous.
  • You can be anonymous with adequate precautions.
  • You cannot send BTC to an invalid address. Typos are not a worry as the payment will refuse to send.
  • The wallet file holds the keys that allow spending and thus the computer should be protected from the risk of loss and theft.
  • Leaving Bitcoin open improves connectivity for the network and ensures that you don't fall behind on the block chain. Also see the FAQ about port forwarding

Block chain

The block chain is a never-ending story of every transaction throughout the network from day 1 (genesis). The first time you run Bitcoin, it is downloaded and verified on your computer. Every new transaction is added to the end of this chain and verified by the network to be valid.


Whenever you send a coin, you are actually sending a cryptographically signed message, associating your coin with the recipient's address. This effectively transfers ownership to to the recipient. Once they own the coin, they are free to transfer it to another person.

A wallet is a collection of addresses. You can create as many new addresses as you wish; having more addresses makes you more anonymous, because then people cannot see how much BTC you received. Your wallet contains the secret keys used for spending that money, and must be backed-up regularly. If you lose the wallet then you no longer possess the money.


New coins are mined through generating hashes. These generators are rewarded with a small fee for the computationally intensive task of incorporating your transactions into the block-chain. This fee halves each time 210000 blocks are added to the block chain, or approximately every 4 years. The fee will keep halving until it effectively reaches zero, at which point 21 million coins will be in circulation.
