$BTC

Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an anonymous person or group using the name Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network that allows users to send and receive digital money without the need for banks or intermediaries. Bitcoin uses blockchain technology to record all transactions on a public ledger, ensuring transparency and security. Its supply is limited to 21 million coins, which helps maintain its scarcity and value over time. BTC is widely used for investment, online purchases, and as a store of value, often referred to as "digital gold." Its price can be highly volatile, driven by market demand, news, and investor sentiment.
