I think the best way is to evaluate the idea, and then assess the capabilities of the team in this area.

In fact, I also believe that the most important thing in any project is the professionalism of his team. Many overestimate their strength and when faced with problems during ICO they can not find solutions to the problem and thus the project becomes unsuccessful even if the idea of the project was initially very interesting and the product was useful. I always study the team, their past experience in similar fields of activity, merit and much more. It is also important to look at the advisors of the project and if among them there are well-known personalities, then the project deserves attention and it can be considered as possible investments.
