A New Kind of Money
Bitcoin is the world's first advanced peer to peer decentralized currency .
The system enables payments to be sent between users without passing through a central authority, such as a bank or payment gateway. It is created and held electronically. Bitcoins aren’t printed, like dollars or rands – they’re produced by computers all around the world, using free software.
Bitcoin is not the only cryptocurrency available, although it is the major currency in the crypto-world. There are many other currencies such as Ethereum, Decred, Dash, Monero etc.
