$BTC Bitcoin (BTC), the first decentralized cryptocurrency, was created in 2009 by Satoshi Nakamoto. Operating on a peer-to-peer blockchain, BTC enables secure and transparent transactions without intermediaries. Its fixed supply of 21 million coins, with over 19.7 million mined by June 2025, drives scarcity and value. The price of BTC, which has historically been very volatile, soared to $69,000 in 2021 and is around $100,000 today, driven by institutional adoption and halving events that reduce miner rewards. Used for payments, investments, and as a store of value, BTC faces challenges such as regulatory scrutiny and energy-intensive mining. Despite competition, Bitcoin remains the dominant cryptocurrency, shaping the future of finance.
