Bitcoin has always been the leading currency in the crypto market, providing relative stability compared to altcoins. With a supply limit of only 21 million BTC, Bitcoin has the characteristic of being a 'store of value' and is considered digital gold. Supported by a strong community, major financial institutions, and the development of DeFi applications, Bitcoin is increasingly becoming an attractive investment asset. However, high volatility and factors such as the monetary policies of countries remain potential risks.
