Nowadays many people think this forum is a source of income, I don't know why they think like this. This is forum to discuss about bitcoin, not for work! If you want to get money, focus on 1 skills what you good or like... And apply on freelance site. Actually you can earn more money by that's job.
Bounty campaign is not worth it, only wasting your time with worthless coins, avoid it.
Keep in mind, signature campaign is only a bonus from your dedication to forum... similar like people give merit (bonus) on a high quality post.
Signature campaign is part of bounty campaign if you are good at doing something why not do it while getting paid,I don't think bounty campaign is now worthless if it is then why is it that many still participating in bounty campaign, it's still profitable, it's just finding the right project to join is the big issue.
