More and more people are getting annoyed with the icos especially due to slow and low last year, most of ico investors from last year are in massive loss and now people want to get rid of all these ico based projects and looking for better alternative and this space may well be filled by security tokens offerings or stos, where the investor becomes a shareholder, part owner and is able to receive profits generating by the project, i think sto model is both more suitable and attractive for investors and next trend seems to be the sto.
