You should still join airdrop because there are still a lot of ICO's that are legit and give tokens. But put much your time and effort on bounties. It gives much more earnings than airdrops. Do airdrops once your done doing bounties, in that way you can have much more earnings.
i've been searching for ico's too that will guarantee a payback for what i will work on it and found about BITXOXO. It seems good since i've read positive comments about it. Wish it gives profit.
I think its a good idea to have a prepaid gift card that can used for transaction but is there an expiration for the remaining balance in the gift card or if its unused for instance?
We never can tell. It depends upon the decision of the developer or the bounty manager. It depends also if your bounty is a legit one or if your unlucky, there will be no payment if it was a scammed bounty.
Bitcoin won't totally eliminate unemployment. It can just support what are our needs and wants but will never replace a formal employment. Earning through bitcoin is not stable unlike formal employment you will still receive your earnings weekly, bi weekly or monthly. Bitcoin gives us profit unexpectedly and we're thankful of that.
