You are gradually participating in a bounty campaign from a reputation manager, I have seen many of his bounty campaigns successful. I think you did the right thing when participating in campaigns from reputation managers, it limits your risk somewhat. Good luck with your campaign.
Some points can help bounty hunters to limit the risk of failure, including joining a bounty managed by a reputable manager, guaranteed escrow payouts, especially for stable coin payouts or coins that have been listed on the market. So both are important points that bounty hunters must pay attention to.
