Bitcoin, launched in 2009, is the world’s first decentralized digital currency. Unlike traditional money, it is not controlled by any bank or government. With a maximum supply of 21 million coins, Bitcoin is often called “digital gold.” It allows fast, secure, and borderless transactions using blockchain technology. People use it for investment, online payments, and international remittances. As global interest in cryptocurrencies grows, Bitcoin is playing a key role in the future of finance. Despite volatility, it remains the most trusted and valuable crypto asset today — symbolizing financial freedom and digital innovation.
