$BTC Bitcoin (BTC) is the world’s first and most valuable cryptocurrency, launched in 2009 by the anonymous creator Satoshi Nakamoto. It operates on a decentralized, peer-to-peer blockchain network, enabling secure and transparent transactions without intermediaries. Bitcoin’s limited supply of 21 million coins makes it a scarce digital asset, often referred to as "digital gold." It is widely used for investment, trading, and as a hedge against inflation. In 2025, Bitcoin reached new all-time highs amid growing institutional adoption, ETF approvals, and favorable U.S. legislation. As the foundation of the crypto market, Bitcoin continues to drive innovation and shape financial ecosystems globally.
