I believe that for a good earnings on bounty you have to make very high quality content. Simple actions in social networks will not be enough. You need to improve the quality of their knowledge, to learn to become familiar with the projects and to write high-quality texts in their blogs. In addition, you can make a video to earn as it should. But the increase in interest on the bounty is hardly to be expected. It's just unprofitable. In addition, a lot of non-professionals participate in such campaigns, which does not justify the increase in the amount of payments. Learn, develop, make quality content and you will be happy.
