It's so hard now to find a good bounty. eCoinomic.net platform is running one now and it looks pretty solid and trustworthy, they also predict a balanced growth for CNC token https://bitcointalksearch.org/topic/m.29799978
But how do you guys know if your bounty is trustable? Why do you personally trust bounty you're participating in right now?
If authentic bounty campaign is selected then i think its not wastage of time but good source of passive income.I have joined lot of bounty campaigns and earned handsome amount other than my regular job.But always be cautious while selecting bounty because if you have selected scam bounty then all your efforts will go useless.I conclude that bounty are best passive income.
