Many ICO have a good appearance only in the surface. Be careful and keep seeing their performance too in their project, especially in their website. See what is their goals, is it realistic or not and you should do some research before investing in their team.
Many developer use fake team, fake profile picture on their website to make investor interested, I know some project who use fake document and looks really true to make investor more interested with their ICO coin. I think how to get profitable with ICO investment is waiting how road map are clearly when publishing and how long ICO coin sale running until listing on exchange market. Will have new ICO make schedule when listing and which one market become destination for listing their coin. When you get an ICO project not clearly how long time for selling running better left and join other ICO project.
