In my opinion if one ico will do a 5x or 10x. That doesnt matter. Bounty hunters can dump their tokens or not. That is not important in my opinion. If a good project will do that amount of x. It can do . If bounty hunters will dump these tokens again it have to do that x if it will do that.
Because i believe marketmakers and investors who couldnt invest during ico deciding these roi. They are cause that. So i think if bounty hunters will their tokens that is not effect token price very much. and bounty hunters can do everything with their tokens.
