Bitcoin, also known as BTC, is a digital currency released in 2009 by a group of men known as Satoshi Nakamato.

Bitcoins can be traded instantly* by anyone to anyone. The only requirement for using bitcoins is having an address to a wallet. You can acquire such an address through the softare provided by the bitcoin maintainer, other third party wallet software, or multiple online wallet services.

Bitcoins can be acquired through mining with your CPU or GPU (video card), or purchased from dealers and bitcoin exchanges.

Getting started

The first thing you will have to do in order to enter into the bitcoin world is to get a wallet and bitcoin address. This can be done using an online wallet service or by downloading the official client from the link below.

As of 2013-04-01, the official client requires 7.95GB of hard disk space to start with, and that will grow with time. The reason for this is that the block chain which holds all of the transactions is downloaded and stored locally. The block chain holds the required information for all transactions made on the network. You can use the block chain to verify that transactions are real, and to verify if payments have been sent or received.

Using an online wallet can help avoid storing 8GB+ of data on your local disk drive, but you are also entrusting all of your bitcoins with the online wallet service. For some people, the benefits, such as access to the wallet from anywhere you can get online, might outweight the risks of having to trust the provider and their security.

The following links are the beginners essentials. You can download the official client from the site linked below:

• Download the official Bitcoin wallet, Bitcoin-Qt
• The official Bitcoin website
• We Use Coins - learn about bitcoins; basic information
• The Bitcoin Wiki - a lot of information
• Bitcoin Charts - realtime quotes from the major sites
• Bitcoin Block Explorer - stats from the bitcoin network
