Bitcoin Beginner
Bitcoin is the original and biggest cryptocurrency: a decentralised digital money capped at 21 million coins.
Launched in 2009 by the pseudonymous Satoshi Nakamoto, it runs on a proof-of-work blockchain kept honest by miners. Its scarcity and role as the market’s anchor asset are why people often call it "digital gold".
