I also make extra money on the forum through Bounties and Signature campaigns, which has been a lifesaver for me because it's a reliable source of income.
I think this forum definitely provides an opportunity for additional earnings, which is very helpful, because some companies pay very well (now it's about bitcoin signature campaigns). I see this when I look at the offers in Services. However, as a member, it is still difficult to call this income a lifesaver, because for our position, earnings are not very high. It motivates me to try and strive to increase my rank, then the extra earnings will really be more significant.
