$BTC or Bitcoin, is the pioneer of decentralized digital currencies. Launched in 2009 by the pseudonymous Satoshi Nakamoto, it introduced blockchain technology to the world. With a capped supply of 21 million coins, Bitcoin is often seen as "digital gold"—a store of value and hedge against inflation. It operates without a central authority, powered by a global network of miners and secured through proof-of-work. Over time, $BTC has grown from a niche experiment to a mainstream financial asset, influencing markets, policies, and innovation. Whether seen as a currency, commodity, or ideology, Bitcoin continues to redefine the meaning of money.
