I suggest every new projects team should do this if they want to introduce bounty campaigns for their project, doing this will limit the risk for tokens losing huge value because bounty hunters sell their shares.
1. Find good bounty manager
2. Give up only few decent allocation
3. Go for strong exchanges with no fake volume
4. Accept limited participants in your bounty campaigns
5. Introduce phase distributions
I think if any project is really doing something for the crypto space then they would have a proper marketing plan. Only low quality or any project that aims for exit scam will promote their project for free. Some high-ranking members suggest joining only those project that is managed by reputable BM or higher-ranking members. Bounty allocation will not be a problem if that project is good. Hunters can not dump a million dollars market easily.
