$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created by an anonymous person or group under the pseudonym Satoshi Nakamoto in 2008. It operates on a decentralized network, utilizing blockchain technology to facilitate peer-to-peer transactions without the need for intermediaries like banks. Bitcoin is often referred to as "digital gold" due to its limited supply of 21 million coins, which creates scarcity and has contributed to its value over time.

BTC transactions are verified by miners through a process called proof-of-work, where they solve complex mathematical problems to add new blocks to the blockchain. Bitcoin has become a popular asset for investment and has sparked the development of thousands of other cryptocurrencies. Despite its volatility, it is often seen as a store of value, a hedge against inflation, and a potential alternative to traditional fiat currencies.
