$BTC Bitcoin (BTC) is the world's first and most popular cryptocurrency, revolutionizing the financial industry with its decentralized nature. Launched in 2009 by the mysterious Satoshi Nakamoto, BTC operates on blockchain technology, ensuring secure, transparent, and immutable transactions. Unlike traditional currencies controlled by central banks, Bitcoin is maintained by a network of miners who validate transactions through a process called proof-of-work. With a fixed supply of 21 million coins, Bitcoin is often seen as "digital gold," offering a hedge against inflation and economic instability. Its adoption has grown globally, with businesses, investors, and even governments exploring its potential as a store of value and medium of exchange.
