$BTC Bitcoin ($BTC) is the world’s first decentralized digital currency, launched in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a peer-to-peer network using blockchain technology, which ensures transparency, security, and immutability of transactions without relying on a central authority. Bitcoin is limited to 21 million coins, making it deflationary by design. It is widely used as both a store of value and a medium of exchange. Over time, Bitcoin has become a symbol of financial independence, attracting investors, institutions, and advocates of decentralized finance seeking alternatives to traditional banking systems and fiat currencies.
