$BTC **Bitcoin (BTC)** is the world’s first and most well-known cryptocurrency, created in 2009 by an anonymous person or group using the name **Satoshi Nakamoto**. It operates on a **decentralized, peer-to-peer blockchain network**, allowing users to send and receive digital money without the need for banks or intermediaries. Bitcoin has a **fixed supply of 21 million coins**, making it deflationary by design. It’s often seen as “digital gold” due to its store-of-value characteristics. BTC is used for investment, payments, and as a hedge against inflation. Its price is highly volatile and influenced by market demand, regulations, and global events.
