$BTC Bitcoin ($BTC) is the world’s first and most prominent cryptocurrency, launched in 2009 by an anonymous creator known as Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, which ensures transparent and immutable transactions. Bitcoin has a fixed supply of 21 million coins, making it deflationary by design. It's often called “digital gold” due to its role as a store of value. $BTC is widely used for investment, remittances, and as a hedge against inflation. Its price is highly volatile, influenced by market sentiment, macroeconomic factors, and adoption trends across institutional, retail, and governmental sectors.
