$BTC Bitcoin (BTC) is the world’s first and most popular cryptocurrency, introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, which ensures transparency, security, and immutability of transactions. Bitcoin is often called “digital gold” because of its limited supply — only 21 million coins will ever exist. It is widely used for investment, trading, and as a store of value. Bitcoin’s price is highly volatile, influenced by market demand, regulations, global events, and investor sentiment. As a pioneering asset, BTC continues to shape the future of digital finance.
