As long as new projects and coins enter the cryptocurrency world, as well as this forum exists, Bounty programs will run. These new projects and old projects which wish to refine their strategies need the help of bounty hunters to spread the awareness across all over the globe.
Even in spite of the fact that now the market situation is bad and not the best time for projects and, accordingly, for bounty campaigns, I believe that the projects will continue to allocate funds for their implementation, as this will help them in development. There is no reason for concern that bounty campaigns may disappear.
