Everything in crypto now is all about how much bitcoin or ethereum you are ready to pay, more than 50% of those ico rating site are just there for money, if you want to get good rating pay higher amount of bitcoin or ethereum. It's pathetic anyway, they are just misleading crypto investors, so I don't believe them. I have seen some ico that got a good rating on theese rating site but ended up been a scam but there are some genuine ones though
