I agree, there are many projects that we spend our time on, and then it turns out that the project is fraudulent. But the fact is that there are real and honest projects, but due to circumstances they failed to realize their plans and make their coins promising and in demand on the market. There are many factors that affect the success of the project and no one can anticipate them, so to minimize the risks, you need to carefully study the projects in which you are involved and if you do not like something just passing by.
