$BTC $BTC refers to Bitcoin, the world’s first and most well-known cryptocurrency. Launched in 2009 by the pseudonymous Satoshi Nakamoto, Bitcoin operates on a decentralized blockchain network, allowing peer-to-peer transactions without intermediaries like banks. Its limited supply of 21 million coins makes it a deflationary asset, often compared to digital gold. Bitcoin is used for investment, payments, and as a hedge against inflation. Its price is highly volatile, influenced by market sentiment, regulation, adoption, and macroeconomic trends. As of now, $BTC continues to dominate the crypto market and remains a central figure in debates around the future of money.
