Mostly we can find a trustable ICO in this forum site's that belong to one of the link in here's.its hard to believe that an ICO is scam or not ,because even for the first time i've not heard a new's that there is an ICO project not legit.maybe there some ICO  that they cannot pursue there goal,because lack of funding and support of investor or a team.maybe a  lack of presentation in the media thats why its not marketable.
