So, what do you think about the future of bounty? It looks uncertain to me!
Well, as you have said, it's certain: certainly dead 
I can't see any reason why anyone could expect another great bounty hunting time after all these ICO/IEO that mostly flopped. I definitely wouldn't waste my time and energy hoping for bounty and would use my time to develop another skill instead.
It is quite indeed that it is so hard to find a very reliable bounty that we can join, I dont know any bounty that I will invest my time and effort. It is affected by the current state of bitcoin, bitcoin is uncertain also that is why most of the bounties before failed to have a good and huge sale because of that. Since halving will happen I hope that good bounties will come out.
I don't think this halving will bring back good bounties from dead. Heck, even a new ATH for Bitcoin and major alts probably won't do either.
