Many blockchain projects are essentially a zero sum game, that is, putting money in one person's pocket into another person's pocket. This is a non benign, but also an industry phenomenon. It causes losses to the vast majority of investors. The root cause of this phenomenon is that many blockchain projects only tell customers about their money making effectiveness, do not solve the actual needs of users, and do not solve practical problems and create value for users. This leads to many projects can not have a relatively long period of operation.
