Tom Lee, chairman of Bitmine, has attributed Bitcoin's recent drop below $86,000 to an exchange glitch and the activation of an automated deleveraging (ADL) feature. According to Lee, the incident was triggered by an erroneous stablecoin depegging, which set off the ADL and intensified the sell-off. Additional factors included leverage-induced panic and a significant BTC dump by a large whale. The market turmoil coincided with a 1.56% decline in the S&P 500 on Thursday, while crypto liquidations surged to $954.55 million over the past 24 hours. Lee assured that the exchange flaw responsible for the crash will not recur, likening the event to a previous market meltdown on October 10th.
