Bitcoin (BTC) is the first and most well-known cryptocurrency, launched in 2009 by the pseudonymous creator Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, enabling secure and transparent transactions without intermediaries like banks. Bitcoin's supply is limited to 21 million coins, making it deflationary by design. It's widely viewed as digital gold, used both as a store of value and a speculative investment. While its price is volatile, Bitcoin has gained mainstream adoption and institutional interest. It plays a foundational role in the broader cryptocurrency ecosystem and continues to influence financial innovation worldwide.
