It's very painful to open an order

Just say it once. Event contracts cannot be touched because there are too many good other opportunities, no need to gamble, and the odds are 1 to 0.8. I also released my best records; even someone like me will lose money. If you think you are better than me, then go ahead and gamble. I haven't lost much, just a few hundred U, and I once fantasized about hitting two or three consecutive wins and doubling my bet, but Binance set a limit, so I couldn't double my bet. I can advise everyone as much as I can; although I haven't lost much, after getting emotional, I calmed down and thought it over, and in the end, I understood. Just focus on trading grids and shorting altcoins.
