$BTC is the ticker symbol for Bitcoin, the first and most widely recognized cryptocurrency. Created by the pseudonymous Satoshi Nakamoto in 2009, Bitcoin operates on a decentralized network using blockchain technology. It is often referred to as "digital gold" due to its store of value and limited supply of 21 million coins. As the leading cryptocurrency, $BTC is considered a hedge against inflation and a popular investment asset. Its price is known for significant volatility, often influenced by market sentiment, adoption rates, regulations, and macroeconomic events. Bitcoin's impact extends beyond finance, shaping the future of digital currencies and decentralized finance (DeFi).
