$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, launched in 2009 by the mysterious Satoshi Nakamoto. Built on blockchain technology, BTC allows peer-to-peer transactions without the need for banks or intermediaries. It’s decentralized, finite in supply—capped at 21 million—and often referred to as “digital gold” due to its scarcity and store-of-value potential. Bitcoin has sparked a global financial revolution, challenging traditional monetary systems and inspiring thousands of other cryptocurrencies. Its price is known for high volatility, influenced by market sentiment, adoption, regulation, and macroeconomic trends. Investors view BTC as both a risky asset and a hedge against inflation. Whether praised as a freedom tool or criticized for speculation, Bitcoin continues to redefine the future of money and finance.
