The best time to promote bounties are on altcoins season ,if you are tired of one delay after the other just quit till altcoins season returns ,this is the reason why 2017 was the best year for bounty hunters
I have not seen anything volatile and good for the alts now. just as bitcoin is falling more than alts, bitcoin dominance goes down but the value of alts doesn't increase significantly.
I think we still need to wait a long time for the market to grow strongly. I think it will be 2020 or 2021.
