It's very difficult to make money by shorting in this market. Taking the recently popular River as an example, this coin rose from 1.8 to 88. Let's not focus on how many casualties of short sellers it took to get there. When it reached 80, everyone knew the market maker would start to dump, and the price would fall. However, the "dog" market maker manipulated the funding rate to -2, with hourly settlements, causing those shorting to also lose money. Those who didn't short didn't dare to enter, and the "dog" market maker only closes long positions.
