According to The White House (@WhiteHouse), Memorial Day ceremonies at Arlington National Cemetery on May 26, 2025, served as a reminder of US national holidays' impact on financial markets, with US stock exchanges closed and reduced trading volumes across both traditional and crypto markets (source: The White House Twitter). Traders should note that such holidays often lead to lower liquidity, which can increase volatility in crypto markets as global participants continue trading while US-based investors are less active.
