$BTC

Bitcoin (BTC) is the world’s first decentralized cryptocurrency, created in 2009 by an unknown person or group using the name Satoshi Nakamoto. It operates without a central authority, using blockchain technology to enable secure, peer-to-peer transactions. Bitcoin has a limited supply of 21 million coins, making it scarce and often referred to as "digital gold." It is widely used for investment, store of value, and, in some cases, as a medium of exchange. Bitcoin's popularity has sparked the development of thousands of other cryptocurrencies, shaping the future of finance and challenging traditional banking systems globally.
