Bitcoin currently accounts for about half of the total market capitalization of the virtual currency market, with a proportion between 50% and 55%. Usually, this share rises during market downturns; when the market is active and other tokens surge, Bitcoin's weight may slightly decrease. Its total market capitalization is close to 1.2 trillion US dollars, and specific data will fluctuate with price changes. The reason Bitcoin can maintain its core market position for a long time is primarily due to its decentralized characteristics, strong network computing power ensuring its security, and the deeply ingrained image of 'digital gold.' Additionally, as the oldest cryptocurrency, Bitcoin has formed a strong brand effect and community foundation, which further consolidates its leadership position in the entire ecosystem.
