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
If we compare, of course 2017 is a very profitable year and is expected to occur again in the near future. And for myself there is no right time to promote a project, if you want to get income I think every time is the right time to promote a project and the results we get will depend on how the project that we participate in.
