$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, launched in 2009 by an anonymous person or group under the name Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, ensuring transparency and security. Bitcoin’s limited supply of 21 million coins makes it a scarce digital asset, often compared to gold. It is widely used for payments, investment, and as a hedge against inflation. BTC has influenced the rise of thousands of other cryptocurrencies and has gained mainstream adoption, with companies and institutions recognizing its value. However, it faces challenges like volatility and regulatory scrutiny.
