Out of 30 bounties I joined, 2 of it was a scam and 4 was failure or did not reached the softcap. I still believe in bounty campaigns. Others are right, bounty are not passive income. Passive income is something you don't put any time and effort and you will received return out of it. Bounties income is definitely an active income. Because you have to actively participate in the bounties before you will received your shares.
