I got curious was it still profitable to participate in bounty campaigns on the forum I stopped for a long time now since I joined on many campaigns that paid worthless tokens and some of them didn't pay their participants.
Try not to avoid bounties which tokens are traded already. Then your only problem will be projects that refuse to distribute.
Just plain numbers:
Participated in DIA Data signature and social media campaigns - earned around 1.2k USD for 4 weeks.
Participated in FreeTon signature campaign - earned around 700 USD for 5 weeks.
Participated in Interfinex signature bounty - got around 160 USD for 3 weeks.
These are 2020 Q3-4 bounties, the results I remember. Participated here and on neighbor forum. Of course there were bunch of social media bounties with 10-30 USD rewards.
