Well one thing you should always remember about ICO's is that they have a very high percentage of scamming you according to what I have seen past few months . Well I may be wrong , there are few ICO's who have really worked hard proved themselves . But the main problems is , it's really hard to believe in them . Cause there are hundreds of thousands of ICO's out there and it's really to find the perfect one out .
Well this is the main reason why ICO's have to escrow / use alot of their money on advertisement . Also many token ICO's just don't manage to reach that global marketplace and hence having a low value of their token . And sometimes even a bit lower than their ICO price Which usually happens with many of the ICOs.
