It is worth in 2020, but for your main job and main income is not recommended to do at all. For every project they just give you below 100 bucks for every 3 months. This is really low compared to fixed jobs and in 2017 - 2018 it was really better and you could get more with just doing a single project, the difference is really insane.
well, in general, it's still worth it. however, conditions remained the same as in previous years. Not all bounties pay the price they deserve, because we know that some bounties don't pay out, and have no market value as we think. it's just that, some bounties are still quite valuable.
