From your question alone is wrong, and of course the reasons you give are also wrong. Your question is: Bounty hunters killed ICO?
What's the deal with the ICO dying with prize hunters? Of course ICOs die because ICO developers often commit fraud, they don't manage ICO properly, so investors are no longer interested in ICOs.
True, you say the ICO died not because of the prize hunters, but the team that often carried off investors' funds was rife. 2018 many teams were unprofessional, even investors were willing to invest again in ICO, bounty hunters were also not the cause of falling prices because developers were not serious in handling projects.
Yes it's true buddy, ico died not because a bounty hunter or investor, but a deceptive developer, which damaged the reputation of ico who really wanted to develop his project well. So Ico is good to be affected. So it's normal that ico project died because developer is cheats and doesn't run the project properly
