$BTC Bitcoin (BTC), the leading cryptocurrency, continues to dominate the digital asset market with its decentralized and limited-supply nature. Often seen as "digital gold," BTC is widely used for investment, trading, and as a store of value. Its market behavior is influenced by macroeconomic trends, institutional adoption, regulatory developments, and technological upgrades like the Lightning Network. Bitcoin’s price can be highly volatile, driven by global demand and speculation. As of 2025, its market cap remains the largest among cryptocurrencies, attracting investors, institutions, and even governments.
