$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a decentralized network using blockchain technology, allowing peer-to-peer transactions without the need for intermediaries like banks. Bitcoin is limited to 21 million coins, which gives it scarcity and has earned it the nickname “digital gold.” Investors often view it as a hedge against inflation and currency devaluation. While its price is volatile, Bitcoin has grown in acceptance, with increasing institutional adoption, making it a key player in the future of digital finance and decentralized economies.
