$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, launched in 2009 by an anonymous person or group known as Satoshi Nakamoto. It operates on a decentralized peer-to-peer network using blockchain technology, which ensures transparency and security without the need for a central authority like a bank. Bitcoin is often viewed as digital gold due to its limited supply of 21 million coins, making it a popular store of value and hedge against inflation. It can be used for online purchases, investment, and remittances. As adoption grows, Bitcoin continues to influence the future of global finance and digital innovation.
