$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto. It introduced the concept of decentralized digital money, operating on a peer-to-peer network without the need for intermediaries like banks. Bitcoin transactions are recorded on a public ledger called the blockchain, ensuring transparency and security.

BTC is often referred to as "digital gold" because of its limited supply—only 21 million coins will ever exist. This scarcity, combined with its decentralized nature, has made it a popular store of value and hedge against inflation. Many investors and institutions view Bitcoin as a long-term asset, similar to gold.

Bitcoin's price is highly volatile, influenced by market demand, institutional adoption, and macroeconomic trends. It is widely used for online transactions, investment, and as a foundation for financial innovation in the crypto space. Despite regulatory challenges, Bitcoin remains the dominant cryptocurrency, shaping the future of decentralized finance (DeFi) and digital economies worldwide.
