Bitcoin, as the first decentralized digital currency, embodies both technological innovation and financial disruption. Its fixed total supply, anti-inflation properties, and global liquidity establish its status as 'digital gold'. Currently, it faces challenges from tightening regulation, energy disputes, and technological iterations, but the entry of institutions, approval of spot ETFs, and increasing geopolitical risks have boosted its demand as a safe haven. In the long term, Bitcoin may become a store of value outside of sovereign currency systems, but its high price volatility, network congestion, and the risk of a 51% attack still require caution. Its future direction depends on breakthroughs in technological scalability, the degree of integration with mainstream finance, and the collaborative dynamics of global regulatory frameworks, fundamentally remaining an experimental hedge between trust mechanisms and centralized systems.
