$BTC Bitcoin is a decentralized digital currency created in 2009 by an anonymous person or group known as Satoshi Nakamoto. It operates on a peer-to-peer network, eliminating the need for intermediaries like banks. Transactions are recorded on a public ledger called the blockchain, which ensures transparency and security.

BTC is limited to 21 million coins, making it scarce and often compared to digital gold. It is used for payments, investments, and as a store of value. Despite its volatility, Bitcoin has driven the growth of the cryptocurrency market and inspired numerous blockchain innovations.
