My experience in the cryptocurrency market is that as long as you don't hold onto losing positions, the thing I'm least afraid of is going short. This time during the surge, every time ETH rises slightly, I open a 25x short position with about 10u. Currently, the yield is -120%, but as long as ETH drops to 2100 points, the yield will turn profitable, and when it drops to 1900 points, the principal will double. I am confident that it will drop back to this point.
