ChainCatcher message, Matrixport released a chart report indicating that Bitcoin suddenly dropped significantly this morning. Due to insufficient bullish momentum after Monday's trading, the longs that bought Bitcoin last week due to the Federal Reserve's dovish comments may have been liquidated.Today's pullback has no obvious event trigger, suggesting that in a low liquidity environment, long liquidations may be the main cause. If Bitcoin falls below $59,000, it could trigger more market concerns.
