ChainCatcher news, Zhu Su posted that some large holders with significant amounts of cryptocurrency spot are adopting the strategy of "selling spot/buying perpetual options," enticing market makers to operate in reverse. Subsequently, these large holders deliberately cause long perpetual options to be liquidated, thereby obtaining a more favorable exit than directly selling spot in the market.Meanwhile, crypto investor VIKTOR pointed out that the market capitalization of many tokens may be artificially maintained at high levels. He cited the example of the ACT token, which plummeted from a market cap of $200 million to $100 million in just a few minutes, and then continued to drop to $60 million, evaporating about 70% of its market cap within 24 hours.This incident has once again raised concerns in the market about cryptocurrency price manipulation and the authenticity of market capitalization, serving as a warning to investors to pay attention to potential artificial interventions in the market.
