I also being  part of some bounties from January until now, but all I can see is even you made all the task in ICO, at the end you can get any reward to them but the coins/tokens they left you with no value, but not all of that ICO ive participated are not paying to hunters, few of them are paid me, but very disappointed because the reward they promised to get is not happen, but it is ok unlike the other not pays me, bounties are not dying, just do some research to took good one that pays you.
