The ICOs are going to stand for sure. The question that stands is in what kind they will be and are they going to be ICOs (initial coin offering) or something else for the future. The truth is, that there are a lot of pools of investors already, who invests in ICOs for good % and because of that, ICOs will continue as long as there are good ideas and projects.
I guess only 5-10% of ICOs maximum will stand when G13 countries will decide to regulate it hard, there are too many projects that can't even provide contact information for their real-world company...
