Crypto markets tumbled Monday as traders got spooked by the potential selling pressure from bankrupt exchange FTX. Bitcoin (BTC) fell more than 2% and briefly dipped to as low as $24,963 during U.S. morning hours, its first time below the $25,000 level since mid-June. It has pared some of those losses since, now trading at around $25,140, 2.6% lower in the last 24 hours.
