I say it's very declining. when compared in 2017 and 2018 I can even easily hundreds of dollars in one project but since 2020 until now maybe even just once a year earn hundreds of dollars. But whatever it is we should be able to be grateful and continue to work.
I see a lot of bounty users and bounty managers on the forum. Many forum accounts are new, there are no high-quality posts, and they are purely for completing various bounty programs. What I want to say is that this kind of bounty activity is too watery, and there is no gold content. Regardless of whether the bounty manager makes more money, it makes me feel like this is not the place for project marketing and publicity. This is a pure content discussion platform. It is better to spend time discussing project quality and code quality. According to everyone's contribution, get the corresponding reward.
If you are pertaining to signature campaign, I agree to you. I can see that signature campaign members doesn't have any motivation to do a high quality post and it seems that they are not afraid of losing the campaign because of their low quality post since the campaign has a high chance of not paying well. It is the same on their social media campaign which is most likely braindead posts just to qualify for the task. Signature campaign on bounty campaign are significantly reduced since then, I believe that it cost the project owner a little bit of money to run even they are paying their native token to the campaign. Signature codes and profile avatar cost to make that's why most of the campaigns now doesn't have signature campaign. Overall Bounty campaign isn't that much worth it to join, Some bounty hunter just survive because they have multiple account.
