$BNB Bitcoin (BTC) is the world’s first decentralized digital currency, created in 2009 by an anonymous person or group using the name Satoshi Nakamoto. It operates on a peer-to-peer network using blockchain technology, which ensures transparency and security without the need for intermediaries like banks. Bitcoin is limited to 21 million coins, making it scarce and often referred to as "digital gold." It is widely used for investment, trading, and as a store of value. Bitcoin’s price is highly volatile, influenced by market demand, adoption, and macroeconomic factors. It continues to shape the future of finance and digital assets.
