I think 90% is super optimistic. I think 99% will fail and of the remaining 1% only 50% will be incredibly successful. There are currently so many ICO's and so much more to come. The 50% of the 1% will most probably be like a 50 ICO's if there ends up being a total of 10000 ICOs which at the current rate of ICOs is most probably not over exaggerated for the long term.
