Recently i took part in couple of bounty campaigns,and i though i can earn some decent amount through it...but it was a total waste...i took part in targetcoin and coss ico campaign and after 2-3 months i recieved the bounty which is worth only about 8 USD including both 
it was just total waste of effort and time
it was just total waste of effort and timeTruly sad event on happening on you and next time maybe you should calculate the allocated funds given to the campaign what you joined so that you can define that this campaign is worth to join but so far that low payments never happen to me since I'm always scanning the campaigns I wish to join. But anyways goodluck for another campaign and don't feel discourage for that payments and make that as inspirational tool to seek better campaign in the future.
