Expecting too much from bounty campaigns is not appropriate. The price of token is projected but not actual. If project grows , so as the token price. If you are doing any bounty campaign , it means that you believe in that project. So just wait for the growth of the project.
I hope that will bounty hunters think, but unfortunately the sad reality is they just want to sell right away the moment they receive their reward.
Most of my earnings in the past have increase in value because I was able to hold it for awhile and I sell it during the last bull run, so if they'll participate now, hold and wait until the next bull run comes, I believe they will enjoy that moment, but like I said, most of them don't hold.
