$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology to record all transactions securely. Bitcoin is not controlled by any government or central bank, making it attractive for those seeking financial independence. It has a limited supply of 21 million coins, which adds to its scarcity and value. BTC is often used as a digital store of value, sometimes called "digital gold." Its price is highly volatile, driven by market demand, news, and investor sentiment.
