Probably not as we all know, there will be new ways to invest and ICO is already outdated though we might still see some project but i don't expect them to hit the peak again. For sure in the future, there will be a new way to invest and attract more investors and introduce your project, but for ICO they have failed to stay in the competition, and they have failed to innovate that much though of course we should not forget the good projects they have produced over time.
