However, if you want to use Bitcoin for everyday transactions you are going to need a Bitcoin ‘wallet’. A wallet can be installed on your computer or mobile phone or it can be a piece of hardware like a usb-stick. A wallet manages your Bitcoin private keys. To purchase or spend Bitcoins you also need a private key.
Once you have installed Bitcoin Wallet on your phone or computer, you will be issued with a Bitcoin address. You will need this to make or pay for things from your Bitcoin Wallet. You will also create a ‘private key’ in order to use your Wallet. The private key is a secret piece of data (a signature) that proves the transaction came from you and prevents the transaction being altered by anyone else.
