Bitcoin: Each Bitcoin is basically a computer file which is stored in a 'digital wallet' app on a smartphone or computer. People can send Bitcoins (or part of one) to your digital wallet, and you can send Bitcoins to other people. ... You can buy Bitcoins using 'real' money. You can sell things and let people pay you with Bitcoins.
