Crypto KOL and former FTX social partner Benson Sun posted an analysis on a social platform, saying, "Today, at 18:30, ACT suddenly crashed 50%. The cause was that Binance adjusted the leverage position limit of ACT. He could only open a position of 4.5 million US dollars by double leverage. Some market makers' positions exceeded the limit and were directly closed by the market price. After the contract price collapsed, there was a huge price difference with the spot, and the spot also collapsed. The time for Binance to issue an announcement this time was 15:32 on April 1, and the effective time was 18:30 on April 1, and the user response time was less than 3 hours. What's even more outrageous is that on March 31, Binance had issued an announcement to modify the position limit of ACT once, April 1, on April 1. The position limit for low-plus leverage was cut by 50%. Before revising the rules, Binance should first evaluate how many positions will be closed. If any market makers have large positions, they should also notify them in advance. As the industry leader, I hope Binance can handle this incident properly."
