$BTC Bitcoin ($BTC) is the world's first decentralized digital currency, launched in 2009 by an anonymous person or group under the pseudonym Satoshi Nakamoto. It operates on a peer-to-peer network without central authorities, using blockchain technology to record transactions securely. Bitcoin is known for its limited supply of 21 million coins, making it scarce and valuable. It is widely used for online purchases, investments, and as a hedge against inflation. Due to its volatility, Bitcoin's price fluctuates significantly. Many see it as the future of finance, while others debate its sustainability and regulation. Despite challenges, Bitcoin remains a revolutionary asset.
