I think the problem is not only about ICOs, ICO scammers have no fear, they can create a company and run away after raising money in ico, why that is so easy is because of that people invest in ICOs very easily.
First of all before we choose the ICO project, we must better know him of what are their projects. If it is good and trustiable its time we choose.No matter what or who is he or she but the important is we know of their better project.
