The point of bounty campaign is to support company in promoting their business, mostly through social media, content creator (blog, youtube, design, etc), or something has high-exposure of mass-communities. They "use" social-community power to promote what their project does. Then as a feed-back, they give a rewards (can be token, coin, or something). The details of the rewards and what-to-do is different for each bounty project.
