Our best option will be to stay careful and vigilant so that we don't end up in the wrong hands.
Yes it will not work because ICO has become addicting and so is bounty hunting because there is money to it and the demand is great, so do not expect crowdfunding to die, death penalty is to cruel let them have 20 years for every thousand they scam, that will be a very long years and they will rot in jail.
Even if you lost money from these scammers and with so much hatred in your heart, death penalty is just too much.
I also lost some but never thought of this as punishment.
Long jail time is more than enough but that would be a long trial before anyone can have that verdict.
So at the moment, do your very best before investing your hard-earned money.
Crowdfunding projects will always be here because there are people that are always willing to take their risk and we can't stop them.
