Signature campaigns on this forum are very popular since most of the past campaigns have been hugely successful. I want to know if there are other forums like bitcointalk that have high quality bounties. Anyone is free to share.
I'm pretty sure in any other forum with signature space, you could get paid by anyone who wants to promote something if you're famous enough. It's just that signature campaigns are more in the "norm" here on bitcointalk.
I think signature campaigns are restricted to this forum because this forum is more cryptocurrency oriented than all. Bounties do have other options and campaign like social medias and content creation.
Signature campaigns aren't exclusively for anything cryptocurrency related.
