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
everyone is definitely looking forward to the Altcoin season like years 2017 ago but at the moment there is no reason to stop promoting the bounty project because the coins you get from the current project may be will to valuable in the coming year. I hope the Altcoin season will come in years 2020.
