The more they get from the team (payment) the better the rank they will give!
What I am looking for in ICO is looking at MVP, live and working products. Something that really can make a difference. Not just empty words with fancy pictures.
I agree with you. Having been read many reviews of ICO ranking sites, I don't get real analysis on the potential of most of the projects they highly rated. I think these sites are a good way to get aware of new and upcoming projects but never trust hundred percent of their review. It is still better to do your own thorough research about the project before investing.
