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.
Honestly, bounty campaign isn't a waste of time if you know the right bounty to take part in. I've seen friends who earn from bounties here.
And so far this forum is meant for different purposes, some can register for a purpose and focus on it. So far it's not forbidden on the forum. It depends on one's way of life.
And the way you think bounty program is, is not what it really is. It's a way to promote a project with good and quality posts and comments. And earn with it.
When you post a good post and a user see the sticker or signature of the project you use. Your post can actually take their attention.
