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".
This definition is educational and not financial advice. Crypto is volatile and high-risk — always do your own research.
