Some of the sites there is a rating of ICO is not true. And they make research from sources which we don't know. So I am not convinced by them. I prefer to see ICO from a trusted source and we can do an analysis to ascertain the truth.
I only use the ICO review pages for reference and do not over-rely on these reviews because I believe that ICO projects can fully use this evaluation website to PR for their projects. Most of the projects that I invested in by myself analyzed and decided to invest.
