Contrary to all fraudulent projects, there are those that bring investors not a bad income, but they are becoming less and less every day.
How to find a universal technology to find these projects?
This technology does not exist, you just need to be as careful and soberly assess a particular project.
I do not even know how to do this assessment. What are the criteria? Fraud has become so qualitative that sometimes it seems that normal projects are worse than fraudulent ones.
