I admit I can't cope with all ICOs coming out here on bitcointalk. I need to weed out the worst and drill down on a few promising ones. That’s why I’m looking for a ICO ratings site, but there are quite a few and I don’t know which one I can trust. I'm afraid many of these ICO review sites are just bounty hunters.
That’s why I made a simple comparison. I looked at the reviews published at ICORating, Cryptorated, GlobalHalo and Crypto Briefing in 100 days (from Oct 1 2017 till Jan 8 2018) and counted total reviews, average rating, count of negative and positive reviews. Of course each site has its own rating system. I have “normalized” them all to a scale from 1 to 10 so as to compare apples to apples.
Here are the results:
ICORatingTotal reviews: 52
Average rating: 7.81
Positive ratings (positive): 28.9%
Negative ratings (risky and risky+): 9.6%
CryptoratedTotal reviews: 33
Average rating: 5.75
Positive ratings (3.5 or more): 6.1%
Negative ratings (2.5 or less): 21.2%
CryptoBriefingTotal reviews: 24
Average rating: 6.95
Positive ratings (above 80): 41.7%
Negative ratings (60 or less): 25%
GlobalHaloTotal reviews: 18
Average rating: 7.7
Positive ratings (above 80%): 38.9%
Negative ratings (below 70%): 22.2%
ICORating are the most productive, posting a review every other day. I like their reviews, however they seem a bit optimistic with only 1 negative review in 10. Crypto Briefing and GlobalHalo post many reviews that are either positive or negative, with Crypto Briefing a bit more on the critical side. Cryptorated seems more tentative, with most ratings in the golden middle, but their count of positive ratings is the lowest, which is a good thing.
I made my conclusions, but I don’t pretend they are valid for anyone. That’s why I decided to share my data so you can copy my spreadsheet and tweak it:
