They seem biased to me. A friend of mine who's doing an ICO told me that they paid 10ETH for 5 quality ratings and that's that! I noticed that some ICOs with good project, team, and good social media presence are struggling with getting good reviews.
With all that said, should it still be a factor to look at when investing in ICO?
For me, i am not really believe of ICO ratings when I choose to join and participation in the ICO. Reviewed project from ICO ratings just alternative opinion to join and support the ICO. When I choose join and participation in the ICO, I am looking for the concept, vision, mision and the aim of the project that i can get it in the website or its whitepaper. I always choose ICO that offering something make sense and then the target of the ICO (like soft cap and hard cap) is reasonable too. I look at its road map and the capability of team and developer to run the project into the success.
