There are a tone of Bounty campaign that has ended but founders and project team members has refused to list on exchanges or even distribute token to bounty hunters. I think the current market condition is a contributor to this, additionally, bounty hunters tends to dump their token athe whatever price they find in the market and this is the issue with value.

This often happens to campaigns that are mismanaged by BM, if you take the effort to do your task with the most resources, you wont sell your reward for any price. Bounty managers should learn to do their job, stop rewarding lazy hunters or scammers.
