$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by the pseudonym Satoshi Nakamoto. It operates as a decentralized system without intermediaries, based on blockchain technology. Its supply is limited to 21 million units, which gives it deflationary characteristics. It is considered by many as "digital gold" for its ability to store value. BTC has evolved from a technological curiosity to a global financial asset, used as an investment, store of value, and means of payment. Although it faces challenges such as scalability and volatility, its impact on the economy and financial technology remains revolutionary.
