$BTC Bitcoin (BTC) is a decentralized digital currency that has revolutionized the financial system since its creation in 2009. It operates without intermediaries, using blockchain technology to secure transactions. Its issuance is limited to 21 million units, which reinforces its value as a scarce reserve. Over time, it has gained recognition as a store of value and a tool for fast and secure international transfers. However, it also faces challenges, such as price volatility, regulatory concerns, and its environmental impact. Nevertheless, Bitcoin continues to drive innovation in the financial sector and attract the attention of investors and technologists.
