One way to examine ICOs is to do good background research of the people involved. If there is something slightly shady in their history, watch out!
For example, there was plenty of shadiness with the guys behind the Centra ICO, but everyone swept it under the rug and pretended everything was super-legit. We all know how that worked out.
Very important point! I remember saying some fud articles about the team background but nobody paid attention because the ICO was shilled by Floyd Mayweather.
Thanks for the comment
