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.
No this is not different to fiat scammers or con artists. Punishment yes, but not the death penalty. Death penalty should be strictly used for really serious offenses, such as murder and terrorism (albeit the chinese would probably do it, as they do in theory to their corrupt officials).
Also what would you do when the (de-facto) government of a nation is the one responsible for the ICO Scam? Do you have any idea how much was collected and "lost" by the Petro ICO scam? Can you even take them to the Hague tribunal for this?
