Now that everyone knows that icos is overrun by scams, icos will struggle to survive in the future. Only if the problem with the fraudsters is solved, icos can survive in my view.
Only time to solve the problem is not as much as it seems, if you delay the fight against fraud, the trust of people can be completely lost, and this is tantamount to the death of the ICO
It won't be completely lost, but it will take longer to convince those who were skeptic about it to finally start using crypto.
