According to ChainCatcher, Zhao Changpeng posted on a social platform that I know I am not smart. When I don’t understand, I will admit it, and I often feel that those powerful people must have mastered some tricks that I don’t know in order to do what I can’t do. But occasionally, I will find that the most basic rules still apply. It is worth noting that Zhao Changpeng quoted the previous tweet that "DEX is not as good as CEX". In response, Zhao Changpeng specifically explained that in order to avoid confusion, the tweet had nothing to do with the HL incident. It was my previous experience trying to use AstherusHub on the BSC chain, a project in the Labs portfolio. They do not display forced flat prices and use automatic position reduction mechanism (ADL), so similar problems will not occur today.
