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.
As the market falls, it seems that many people are reluctant to trade!
More and more people participate in the bounty activity, resulting in lower income!
Many fake ico also appear, many bounty hunters do not receive the payment after work!
