The one way to revive ICO from it's death bed is if it become legalized, it will take time for investors to start jumping right in again but in time things will become better, for now ICO investment is a bad idea and it need to be avoided at all cost
To be compliant with the regulators are not easy dude, you must fulfill all of the requirements. This is a good way to survive the ico but the problem is there is no regulatory framework that was fully controlling the ico.
Ico is bad idea when there was no a middle party who will act as an escrow just like IEO platform that already launched by binance. Investors need guarantee if they will receive what they want.
In this case regulation acts as a replacement for the escrow to give guarantee to the investors.
