This is not a comprehensive list, but we do periodical research and we are monitoring incoming traffic. Bold names indicate a major source of income traffic. Some websites have provided independent ratings (marked with [RATING]):
[RATING](note editor/user) ICO Scroll - note that we strongly disapprove their method of averaging ratings. Since there is no assigned editor rating and everything is zeroes, even after we got a review (which now disappeared?) we still have a 4.5 average, which shows like 2 and 1/4 stars. We will be asking them to de-list Cryptum.
