First of all, you got the key point of this question wrong. What should I pay attention to? Lazy people don't know how to manage money, not that you participate in various pk competitions. Since you don't understand, what's the point of taking part in that competition? Besides, do you know how to manage money in order to participate in that pk? This is not your purpose. I think so. Let yourself know about financial management and become a leader in the financial management industry. If you can't get to the top, at least don't let yourself lose money. If you can manage money, at least don't let yourself lose money. This is your purpose.
