Off course not no bounties will run and will success if their is no bounty hunters because they are doing their job to promote or advertise the project of the bounties so it means bounty hunters is one of the advertiser for them to be popular and to know other investor that their is a new coin that they can earn. So that bounties need bounty hunters for their project.

It is difficult for a bounty to reach the point of success if done without the help of a bounty hunter. Without a bounty hunter, bounties cannot get many relationships easily and quickly. The product cannot be widely known and there is no support from outside parties so that the bounties have difficulties in carrying out their mission to achieve success.

It cannot be any bounty without bounty hunters. The same question is, can an ICO reach 3 million USD soft cap, without any investors? Sounds pretty obvious right? So no, bounties cannot achieve their goals without hunters.

I guess no bounties run successfully without the participation of bounty hunters. Bounty hunters have big contributions in the success of the bounty campaigns. So for those bounty hunter that join the success of the bounty are very lucky enough because they can recieve also big rewards on the campaigns they are joining in.
