that's fine. When you get a low reward and it means if you have joined in the bounty with low allocation with many participants. If you wanna get a decent reward for your effort and you can try to join in the bounty that puts a limitation on its participants. The main concern is if you are putting quantity above everything and then you can at least get a reward from some bounties at the same time. It may be decent reward for you but if you can't get it and just focus on the quality, allocation, and participants. You get a small reward by joining in the small bounty with large participants and you can't blame it. that's your fault. The method used to pay the bounty reward is good enough right now. there's no need to complaint but do your own research.
