These ICO rating sites are everything else but rating sites. Most of them are paid for featured spots. Experts are not experts. Some bots give random ratings. Awful service. Don't use them. Zero value in them.
Obviously! They would rather collect those huge bucks to get their projects out there to their trusted members without considering the long run effect of it. Now, a lot of investors do not really care much about ICO rating websites and will rather go through the necessary details and research by themselves before they even invest in anything.
It is absurd that what was created to help the community at the end just have the motive to get popular for the monetary gain. Not saying the monetary gain is bad, but at least it makes sense to always keep integrity in check.
