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
There are quite a lot of good bounty since BTC comes back to 4K $, if hard working on bounties and I think those people also earned a decent amount of money.
the gift given by bitcoin when bitcoin rises is quite a lot, and sometimes of course many people are very happy with the gift that has been given to bitcoin. because until now many have wanted promising prizes.
