I do not agree with you . Bounty hunters are always blamed for the demise of the ICOs due to dumping but in reality the collapse of the ICO is due to the ICO's lack of appeal to investors buying it. I do not think that a small number can make a ico fail. Also only a small percentage of the tokens are allocated to the bonus campaign.
They should stop blaming those bounty hunters for the failed of the ICO. It's not their fault if that project is not that convincing to the investors. And lastly, not all bounty hunters dumped their coins when it got listed on the exchange. There are some investors who easily dumped their coins after they bought it coz some think that it doesn't have the potential to grow.
