According to @WhiteHouse and @USArmy, the annual 'Flags In' tradition at Arlington National Cemetery, conducted since 1948 by the US Army Old Guard, highlights Memorial Day’s significance in the United States (source: @USArmy, May 25, 2025). Historically, US national holidays like Memorial Day have correlated with lower trading volumes and reduced volatility in both traditional and cryptocurrency markets, as observed in past years (source: CoinMarketCap 2023 Holiday Trading Report). Traders should anticipate decreased liquidity during the Memorial Day period, potentially leading to wider spreads and less predictable price action for Bitcoin, Ethereum, and other major cryptocurrencies.
