$BTC Bitcoin (BTC) is the pioneering and most recognized cryptocurrency in the world. Created in 2009 by an anonymous developer under the pseudonym Satoshi Nakamoto, it revolutionized the financial system by offering a decentralized, transparent, and censorship-resistant alternative. Its limited supply of 21 million coins reinforces its value as "digital gold". BTC is widely used as a store of value and medium of exchange, although it faces criticism for its energy consumption and volatility. Despite competition in the crypto market, Bitcoin continues to lead in market capitalization and adoption, consolidating itself as the foundation of the ecosystem.
