An account can effortlessly be created using an eWallet service. eWallet services provide an online wallet to hold your bitcoins.

This guide covers installing Bitcoin without needing a third party wallet service.

For Windows Computers

Download Windows Bitcoin Wallet at http://bitcoin.org/en/download available in 64bit and 32bit.

Welcome Wizard Screen

Click Next to start installation.

Destination Folder Screen

(Optional) Choose preferred directory then click Next.

Choose Start Menu Screen

Click Install.

Installation Screen

Wait until installation completes then click Next.

Finish Screen

Click Finish to start Bitcoin Wallet.

Welcome Screen of Bitcoin Core Wallet

On the first load, Bitcoin Qt will ask you to choose directory where your Bitcoin block chain and wallet.dat will be stored. Click OK when done.

For Mac OS Computers

Download Mac Bitcoin Wallet at http://bitcoin.org/en/download and expand the disk image.

Contents of the Bitcoin disk image after expansion

Drag the Bitcoin icon to the desired install location, and double-click the icon to run the application.

Initialization

The Bitcoin window will open and connections will start up in minutes. The blocks will begin downloading.

At this point, it is recommended to encrypt your wallet before receiving any bitcoins. Encrypting later may leave earlier addresses vulnerable to theft in the case that the system is compromised. This can be done from the Settings menu using the Encrypt Wallet function.

Main window
Preferences window on Windows

Your wallet will automatically have your first bitcoin address.

Receive coins window

Getting my first coins

You can get your first coins from Bitcoin faucets which gives small amount of BTC for free.

The client will eventually show the transaction.

After about one hour the transaction should get 6 confirmations. You are able to spend the coins once the transaction shows at least 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.

Transaction once confirmed

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

Proceed to the introduction

Technical

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.

Addresses

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 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.

Generating

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.
