As we all know still exit scam ICO's are victimizing investors including me in my frustration I wish these people be killed or if busted they must sentenced to death Penalty are you favor of it.
I believe karma will take care of most of them, and that can take many forms. Some end up in prison and others fear for their lives. Others have accidents. The best solution is prevention rather than revenge, however.
It is really possible to prevent the spread of scams in the ICO.That's just the one who can do it either closes his eyes or he participates in some fraudulent ICO.When investing, you really need to hope and trust only yourself.Since we live in a humane world, I think a prison sentence for fraudsters would be the best punishment.
