$BTC Bitcoin (BTC) is the world’s first and most widely recognized cryptocurrency. Created in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto, Bitcoin introduced the concept of decentralized digital currency. It operates on a peer-to-peer network without the need for a central authority, using blockchain technology to ensure transparency and security. Bitcoin can be used for online transactions, investment, or as a store of value, often referred to as "digital gold." Its supply is limited to 21 million coins, contributing to its scarcity and appeal. Over the years, Bitcoin has influenced financial markets, sparked innovation, and generated global discussions about the future of money.
