We have noticed that a lot of successful ICOs have exhibited common factors. One of these is their use of hype. Another is a detailed presentation of the company's roadmap.
Theres probably a lot of things successful ICOs have in common. However, it should only be one thing that should set them apart, and that is PURPOSE. Any new ICOs or projects should be solving a real problem in the real world.
Without such, the ICO is not heading towards success or anything at all.
