there are ongoing some very interesting ICO, like radix, tezos and maybe Ignis. However remember, last ICO has a lower ROI
But there are other coins, which should be in every portfolio.. XRP, XEM, ETC, ... and there are some coins with very very good growth campanches, like MNE, QTUM, ...
hope this can be useful for you
I'm also looking for interesting ICOs, but Price in most cases is too high, and as soon as the coin come to exchanges, you can buy at lower Price. so i agree minereum is a very Special undervalued Project, with a Investment in mne you could gain more than with current ICO
