I have one question that really bug me sometimes, Are ICOs going to end or new ideas and projects will emerge along with ICOs. Many of us actually rely on bounty to earn other than investing. As long as there is ICO I believe there will be bounty. It will be a sad day for us if ICOs are declared officially dead.
Fall of ICOs is too obvious. There is no regulating body to punish all the scammers and pay all the invested money back, so nothing will change untill the creation of such body. However, I do not think that it may appear in nearest future, so stay away.
