If Ethereum does survive such a bad rap, with episodes of things like Monaco Visa's ICO blowing up in their face, it might be a good opportunity for "Crisis Investing," as coined by Doug Casey... Take your own risks...
As for me, I'm only invested in Ethereum for short term gains. While I view it as an amazing business plan, I think it has poor management. I don't want to lose "big time" when this company goes down like those 911 towers.
I don't agree with Adrian about not checking ICO's for compliance. Think minimally requiring them to be bondable, to have proven physical locations of operation, employees without aliases, and for the CEO's to be required to hold their net worth within the ICO, for me, would just be to start. While it wouldn't weed out a potential Bernie Madoff, it would prevent a lot of future problems.
