$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, introduced in 2009 by an anonymous creator using the pseudonym Satoshi Nakamoto. It is a decentralized digital currency that allows peer-to-peer transactions without the need for banks or intermediaries. Bitcoin operates on blockchain technology, a secure and transparent public ledger that records all transactions. New bitcoins are created through a process called mining, where powerful computers solve complex mathematical problems to validate transactions and earn rewards. With a fixed supply cap of 21 million coins, Bitcoin is often viewed as a hedge against inflation and digital gold. Its price is highly volatile, influenced by factors like market demand, investor sentiment, regulations, and macroeconomic trends. Over the years, Bitcoin has gained widespread adoption, from being used in online purchases to becoming a key asset in institutional investment portfolios. Despite debates about its environmental impact and regulation, Bitcoin continues to shape the future of finance.
