$BTC Bitcoin (BTC) is the world's first decentralized digital currency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a technology called blockchain, a public, immutable ledger that records all transactions. Unlike traditional currencies, Bitcoin is not controlled by any central bank or government, offering a peer-to-peer system for secure and direct transfers.

Its scarcity, with a capped supply of 21 million coins, contributes to its "digital gold" narrative and potential as a store of value. Transactions are verified by a global network of "miners" through a process called Proof-of-Work, ensuring security and preventing double-spending. While volatile, Bitcoin's innovative design and independence continue to drive its prominence in the financial landscape.
