I learn about new ICO from the forum and sometimes from special portals that evaluate ICO and give a brief description of the project.
If I'm interested in the idea, I read more about the project, the team and I'm looking at the information on the forum.
High risk characteristics will be accompanied by high profit expectations and this is something that many people enjoy.

Thus, the amount of investors has disappeared no one is responsible for the whole!
