Bitcoin (BTC) is the first and most well-known digital currency in the world, and it represents the cornerstone of the cryptocurrency market. It was launched in 2009 with the aim of providing a decentralized financial system that is not controlled by banks or governments. Bitcoin is characterized by scarcity, with a maximum supply of only 21 million coins, making it akin to digital gold. Some use it as a long-term investment vehicle, while others prefer it for quick cross-border transfers with lower fees. As institutional adoption increases, Bitcoin remains a focal point for traders and investors worldwide, with price volatility offering both opportunities and risks at the same time.
