there's a lot of things the you should check before you consider that it is indeed a good project/ICO. check the white paper, backgrounds and people behind it, also you could try to check their sponsors and how they manage and run their project. at the end of the day, it's still depends on them. i encounter lots of great and high potential projects but then at the end it doesn't work or they actually failed. better check things out before risking something, never test the water with both feet.
