I completely agree with you! Previously, each ico could gain 100 million in a couple of weeks.Now it can not be done and it's good! Now investors are more vigilant,we are not in 2017.Before I invest in ico I study white paper,team and it is also very important to see them at any conferences .
It's even more important to see the team somewhere at conferences. Developers should present their product not only in white paper. It is better to see real team than read white paper and look for the catch. For example project Menlo.one has not lauch ICO yet, but its team participate in different conferences.
