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.
If nothing is done to prevent the current numerous frauds associated with the ICOs, then yes. It will end someday. People are already loosing interest in ICOs.
