Back in the days when bounty was still a way to earn tokens by posting on your social media accounts, it was much easier to find projects that paid a fair money. However, these days it's much harder to find projects that do so. I would not advise you to participate in a bounty campaign because there are no more reasonable projects available and you will be wasting your valuable time. You can contribute to the forum and gain points that would advance you in the signature campaign rankings.
