Yes, I always read ICO ratings. These ratings are made by smart people with a lot of experience. They often write about the fact that you need to pay special attention on something and where there can be risks. Of course, the investor makes the decision independently, but such ratings pay attention to fraudulent projects.
Can you give examples of ICO ratings that you see and trust? Perhaps among them there are good ones, for example I do not know about. Just a lot of popular ratings place biased estimates on projects. More precisely, good ratings in such ratings are bought, so I do not trust them.
