I do not believe in ratings, because they give false information. It seems to me that we have to independently do a project analysis in order to choose the right projects for investment.
I always trust the ico ratings because they will not give a good ratings if the project is not good. And i believe that having a good ratings can definitely attract a lot of investor to invest on the ico but aside on ico ratings we should also look on the project if they have a good whitepaper.
