The world's largest traditional futures exchange, CME Group, suddenly halted trading 2 hours ago, causing futures for cryptocurrencies like BTC, ETH, SOL, as well as S&P 500, Nasdaq 100, and Fed rate prediction contracts, to be suspended. The last candlestick shows the time as 10:30 AM (Mainland China time). And today happens to be North America's Thanksgiving + Black Friday, the time of the lowest market liquidity.
