$BTC Bitcoin (BTC) is the world's first decentralized digital currency, created in 2009 by the pseudonymous Satoshi Nakamoto. Operating on a peer-to-peer network, it allows direct transactions without central bank or government control, recorded on a public distributed ledger called the blockchain. Initially conceived as a digital cash system, BTC has evolved into a prominent investment asset, often dubbed "digital gold" due to its fixed supply of 21 million coins. Despite its volatility and regulatory uncertainties, Bitcoin continues to gain traction, with increasing institutional adoption and companies like MetaPlanet integrating it into their treasury reserves. Its underlying blockchain technology remains a foundational innovation in the digital asset space.
