I have tried my best to persuade my buddy to take multiple orders. He made a profit of one million US dollars on this order, but he just didn't listen to me. This is really the top, and I really don't want you to lose money. At the beginning of the year, I asked him to take a sell at the highest point of 30000 US dollars and then buy at the lowest point. What's different from me is that he doesn't act recklessly. I told him the general direction and kept holding it, so he won't go short and lose money. At that time, I was also buying at the lowest point. All the money my buddy withdrew was to fill my short position. Last month, I lost 10 million US dollars
