#PI #PI four roles, the first platform, you can see the amount of information purchased, if you buy more contracts, you will fall, and if you buy more contracts, you will rise, because the platform counts the purchase volume. Second, the project party, the project party only for the sake of profit, keeps selling the goods in hand. The third is that the so-called bookmakers will be eaten by the platform and the project party if they do not have a certain strength. The fourth is that poor retail investors, who understand that they think they are smart, and they dare to contract when they make a little money, but they are all cannon fodder, or they listen to the information in the circle, and they have no self-knowledge, remember, no one wants you to make money in it, so you decide your own destiny. The first three are most afraid of playing spot players, you fall his position, sell if you make money, don't chase high, come down to buy, and there is the kind of invulnerability, buy and hold it all the time, never look at it, the ups and downs can't affect it at all, and after a few years or more than ten years, become the biggest winner. A thumbs up for approval
