#广场狂热挑战赛 For me, May 19th does not seem to have any special commemorative significance. I still clearly remember that time, I was full of ETH at a high position and escaped smoothly, and then just watched the drama quietly. Alas, I've never been good at shorting, otherwise I should have given it a try on that downturn where the win-to-profit ratio was such a bargain. But I always like to isolate positions. The worst case scenario is to use liquidation to stop the loss. Even if it does liquidate, it will only blow up the margin. Therefore, what is the full position model? In extreme market conditions, there are really ups and downs. However, for those who do not have a perfect trading system, everything is the same.
