Bitcoin, the world’s first decentralized cryptocurrency, was created in 2009 by the mysterious Satoshi Nakamoto. Unlike traditional currencies, Bitcoin operates without a central authority, relying on blockchain technology to ensure security and transparency. Its fixed supply of 21 million coins makes it a scarce digital asset, often referred to as "digital gold." Over the years, Bitcoin has evolved from an obscure idea to a global financial revolution, influencing economies, industries, and even inspiring the creation of thousands of other cryptocurrencies.
