I'm not a teacher, but this is what I think
. To invest in an ICO I think the most important is to do a thorough and detailed investigation of all aspects of the project and the team. See if the project has a real application, if what it proposes is feasible, real advisors and who are committed to the project, if team members are active and show their identity publicly and at events, investigate past projects in which the team members have involved, and so on. And finally, don't get carried away by the hype or the opinions of others, trust your own criteria.
