Thanks to my great brother, he helped me earn a lot today. This morning I had a 9-game winning streak, and after a break, he gave me another 9-game winning streak. As long as the win rate is sufficient, just keep investing a fixed amount each time. The betting theory I proposed earlier is for those who have no skills and do not want to learn, pure gamblers. In my opinion, event contracts are similar to the options I used to trade, but this thing is a binary option, either 180% or 0, and the expiration time is short. When you invest in it, you have to treat that money as already lost. Losing is normal, winning is the surprise.
