this can be a solution to all these problems but it will also be very difficult to implement because even though investors know that it is very risky to invest in non-certified ICOs but they cannot ignore the ICO because sometimes what ICO offers is like that very tempting
If after the emergence of ICO regulations an investor still decides to invest in an ico or project that is not verified by the regulatory body just because of the tempting offer or bonuses offered by the project then he is fully liable for his actions and should not blame anybody for his misfortune from the project. Because the ICO regulation was created to protect investors from scam and if one investor then decides that he doesn't need that protection then it's nobody's fault.
