$Trump's initial return to the White House fueled a bullish momentum in the cryptocurrency market, but his tariff policies triggered market uncertainty, leading to a decline in cryptocurrency trading volume in the first quarter of 2025. According to a report by Kaiko, trading volumes of Bitcoin and major altcoins fell by 30% compared to pre-election levels, with increased market volatility. Although Bitcoin performed better than most altcoins, its price still dropped by 12%. The market depth on U.S. exchanges helped to mitigate Bitcoin's decline. Despite the increased market uncertainty, investors remain optimistic about the future, anticipating a positive trend in the market in the second quarter. The expansion of the stablecoin market and new cryptocurrency products could serve as catalysts for the market recovery.
