$BTC, or Bitcoin, is the first and most recognized cryptocurrency in the world, created in 2009 by the pseudonym Satoshi Nakamoto. It functions as decentralized digital money, without the need for intermediaries like banks. It uses blockchain technology to securely, transparently, and irreversibly record transactions. Bitcoin has been adopted both as a store of value, similar to gold, and as a medium of exchange in certain environments. Its programmed scarcity (21 million coins) and growing acceptance have made it an influential asset. However, its price is highly volatile, presenting opportunities and risks for both investors and users alike. $BTC
