$BTC Bitcoin is the first and most well-known cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology to enable secure and transparent transactions without the need for intermediaries. Bitcoin’s limited supply of 21 million coins gives it a deflationary nature, often compared to digital gold. It has become a popular store of value, investment asset, and means of transferring money globally. Despite price volatility and regulatory scrutiny, Bitcoin continues to drive innovation in financial systems and remains a key force in the evolving world of digital currencies.
