$BTC Bitcoin (BTC) is the world’s first decentralized digital currency, created in 2009 by an unknown person or group using the name Satoshi Nakamoto. It operates on a peer-to-peer network without any central authority like a bank or government. Bitcoin transactions are recorded on a public ledger called the blockchain, ensuring transparency and security. Its total supply is limited to 21 million coins, making it a deflationary asset. Often called “digital gold,” Bitcoin is used for online payments, investments, and a store of value against inflation. Its price is highly volatile, influenced by market demand, regulations, investor sentiment, and global financial trends.
