$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology to record transactions transparently and securely. Unlike traditional currencies, Bitcoin is not controlled by any central authority, and its supply is limited to 21 million coins. BTC is often referred to as “digital gold” due to its scarcity and use as a store of value. It enables borderless, censorship-resistant transactions and plays a key role in the broader crypto ecosystem. Bitcoin continues to drive innovation in finance and decentralized technologies.
