WHAT IS BITCOIN

A type of cryptocurrency, Bitcoin is a digital currency created in January 2009 following the housing market crash. Bitcoin offers the promise of lower transaction fees than traditional online payment mechanisms and is operated by a decentralised authority, unlike government-issued currencies. There are no physical bitcoins, only balances kept on a public ledger that everyone has transparent access to, that – along with all Bitcoin transactions – is verified by a massive amount of computing power. Balances of Bitcoin tokens are kept using public and private "keys," which are long strings of numbers and letters linked through the mathematical encryption algorithm that was used to create them.
