In fact, the price may not fall so low. Look at BTC. After the limit down, k can be pulled closer by 1% in 1 minute. This means that there are not enough shorts at the current price. This is due to the liquidation of a large number of high-leverage longs and the decline caused by selling. Shorts mainly use large stop-loss and small take-profit strategies to win continuously. Maybe perpetual contracts need to be changed. Longs need to pay 12% annual interest by default, which forces longs to adopt high-leverage strategies. When the market could soar dozens of times a few years ago, this interest rate might be reasonable. But now the market is obviously not rising. There is a ceiling for the rise and no bottom for the fall (it can be delisted at any time)
