#美国加征关税 The impact of the United States' tariff increase on the cryptocurrency market shows characteristics of short-term bearishness and long-term differentiation. In the short term, the tariff policy exacerbates market risk-averse sentiment, leading to the sell-off of cryptocurrencies like Bitcoin, with increased price volatility. For instance, after the tariff announcement in February 2025, BTC once dropped over 7%. In the long term, due to inflation expectations and the weakening of the dollar's credit, it may strengthen Bitcoin's 'digital gold' attribute, attracting safe-haven funds. Additionally, the tariffs raise the cost of mining equipment, squeezing miners' profits, which may accelerate the centralization of mining. Demand for stablecoins may increase, but regulatory uncertainty is rising.
