$BTC Bitcoin (BTC) is the world’s first decentralized cryptocurrency, created in 2009 by an anonymous person or group known as Satoshi Nakamoto. It operates on a peer-to-peer network without the need for intermediaries like banks. Transactions are recorded on a public ledger called the blockchain, ensuring transparency and security. Bitcoin is limited to 21 million coins, which gives it a deflationary nature. It's widely used as a digital store of value and is often referred to as "digital gold." Bitcoin’s price is highly volatile, influenced by market demand, investor sentiment, regulatory news, and global economic trends.
