Unfortunately bounty earnings are not so high as were just 3-4 months ago. More people participate thus earnings decrease. In addition to that there is more scam and market has been in a slump lately. However I can suggest some cool bounties: Effect AI, Shivom, 47 bank, open collectors.
Thats true, since last november I noticed that bounty participants increase so the bounty rewards rewards decrease. Ive participated in blocklancer bounty and got small amount of tokens for 8 months because of the 18,000+ bounty participants. Try on participating in shivom and pecunio bounty. I believed in this projects, you might want to see this
