I always believe on a great ICO with a great campaign manager, because all ICO are really promising but not all are legit so we have to be more careful on joining ICO. I believe all ICO have a future if the team are really serious on the project, and hopefully no more scams ICO.
Isn´t possible to generalize each one equally,on the one hand there are projects that seem quite feasible and with very interesting features,but unfortunately some others are not real or are not what they claim to be,so before investing, it's good to do a study first and be very careful before doing it,because the worst thing would be to invest in a fake project,perhaps over time there are mechanisms that better regulate this fact.
