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.
Well, I contacted all of them and yes, all of them cost. The only unpaid ICO listing ones are the one done by privates or pools, about which I don't have any data, but all the ICO listing websites work upon payment. I agree it is hard to go through all of them, but filtering out projects should be done somehow differently.
