Do you think people here can answer that accurately? If a person knows that a certain project will be succesful then they might be richier now. All ICO's have wonderful roadmaps that can lead to good future. The questioned is, how is true at all?

This is about putting some risk. No matter how beautiful the project is there are still chances of failure. Up to you to decide if you still want to invest based on your guts or based on other's speculation.
