Bitcoin is Bitcoin, the first digital currency introduced in 2009 by an anonymous figure named Satoshi Nakamoto. Bitcoin operates on blockchain technology, which enables secure, transparent transactions without intermediaries like banks. Its popularity continues to grow as an investment asset and a global payment tool. Its volatile value makes it both attractive and risky for investors. Additionally, Bitcoin has driven the development of a broader crypto ecosystem. With a limited supply, Bitcoin is often called "digital gold" and is considered to have great potential in the future of an increasingly decentralized and autonomous global financial system.
