If Bitcoin (BTC) returns to $100,000, it will represent a renewed peak of global confidence in decentralized assets. Such a price recovery is typically accompanied by macroeconomic factors such as the depreciation of the dollar, rising inflationary pressures, monetary easing policies by central banks around the world, or global geopolitical instability. Additionally, the popularity of Bitcoin spot ETFs, participation from mainstream financial institutions, and the supply-demand changes brought about by the 'halving' effect may also be important factors driving the price increase. However, a rapid price surge may also bring about bubble risks and volatility, and investors should remain cautious to avoid excessive chasing. Overall, Bitcoin's return to $100,000 is a reaffirmation of its status as 'digital gold' in the market and symbolizes the trend of blockchain assets becoming increasingly mainstream.
