Many analysts predicted the fall of ETH long before the price reduction. I think that they were just able to predict the behavior of this coin, given the extinction of the ICO industry.
This was really talked about long before the fall. I dont think that now the ICO has reached a critical point. At the moment there are still many unrealized ideas. 1 or 2 years, the ICO will not disappear anywhere.
It will not because it's following the trend of bitcoin. when the big bullish comes and then it will be so easy to attract more users to participate in the ico. As long as it's created by the trusted team and then it will be so easy to encourage the demand for that ico. That depends on how good that ico is and how much hype that has been getting by the team.
