The so-called teacher of CMC teaches you how to make money. First, build a group, and then a group of people continue to talk about how good the teacher is, how much money they made, thank the teacher in various ways, and then say how much money they have invested and how much they made. Others followed the investment and even some people borrowed money everywhere to invest. After that, the funds could not be withdrawn, and they contacted customer service. The customer service said that the funds were frozen and needed 10,000 yuan to unfreeze. After that, except for the victims, the scammers were not found.
