What is Bitcoin?

Bitcoin (BTC) was the first cryptocurrency, launched in 2009. It introduced the idea of a digital money that no single company or government controls, with a fixed maximum supply of 21 million coins.

How Bitcoin works

Bitcoin transactions are recorded on a public blockchain and confirmed by a global network through a process called mining. Once confirmed, transactions are extremely difficult to alter. There is no central operator — the network is maintained collectively.
