Yes, most of ICOs right now get dumped after the release of the tokens especially on the first exchange. To know if the coin has a future, all these questions must be answered by YES. First, is the team still working hard to continue the project? Because after the ICOs if the project is discontinued it only means it is a scam. Second, check social media account if they are still active, no activity and you know what it means. Third, is their marketing department continues to advertise and promote the project? No marketing plans and advertisement = fail project.
