$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, launched in 2009 by the mysterious creator, Satoshi Nakamoto. Designed as a decentralized digital currency, Bitcoin allows peer-to-peer transactions without the need for banks or intermediaries. It operates on a secure, transparent blockchain network where every transaction is recorded. Over the years, BTC has become both a store of value, often called "digital gold," and a speculative asset for traders. Its limited supply of 21 million coins drives demand and price volatility. Bitcoin continues to shape the future of finance, inspiring countless other cryptocurrencies and blockchain projects globally.
