There is no variety to judge. Each variety has its own characteristics, and the so-called good judgment is only aimed at different types of people. Judging from your appearance, you have never done futures. I understand what you think now, which is similar to what I thought before, but I want to tell you that you can have this idea, but don't put it into action. It's best to make some relatively stable varieties at first, and then make some fierce varieties after you have some experience. Of course, if you are sure that you are lucky, or you have enough money for you to lose, or you want to lose everything, then you can choose a fierce variety, which will make you infinitely satisfied.
