Check at
www.icoguide.com this is very good platform, easy to compare different projects.
ICO Listing websites are not trustworthy. They work this way: you pay, you get listed and get graded. You stop paying, your grade decreases. Total bullshit.
I do not think that all listings are paid, besides it is way to filter out some projects with better potential, as it is very difficult to go through all ongoing projects especially in the situation when there so many of them. Of course while investment we should not rely only on the rates.
