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.
It is unlikely that someone will give an exact answer to this question. But I believe that the ICO market will not end in the foreseeable future. It is very useful for modern digital society and investors. Even in a falling market period, new and successful ICOs with promising ideas and technologies regularly appear.
