Bitcoin (BTC), the first cryptocurrency, remains the dominant player in the crypto market with a **$1.2 trillion+** market cap. Known as "digital gold," its **21 million supply cap** ensures scarcity, driving long-term value. Recent developments include spot **Bitcoin ETFs** boosting institutional adoption and the **2024 halving**, which reduced miner rewards to **3.125 BTC per block**. Despite volatility—dropping below **$20K in 2022** before rebounding past **$70K in 2024**—BTC thrives as a hedge against inflation and fiat devaluation. Regulatory challenges persist, but growing global acceptance cements its role in the future of finance.
