I don’t know why I think you’re sounding like someone who is already feed up with bounties even before they start 😂 but regardless, there are people who are doing absolutely well off bounties and as hard it might seem to believe, but it's just the bitter truth and it doesn’t seem profitable to you doesn’t also mean others aren’t combing in some reasonable amounts from bounties by doing the right thing and joking the right bounties.
Some persons might want to ask me, how we they know which bounty is a good one (sorry to say that, I also don’t know because I really don’t do bounties and can’t actually remember doing anyone in recent time) but there are people who know this things.

I think just as other users have already said, currently now, a lot of bounties and airdrops seem like scam but there are also some legit ones that people are already earning very well from it.
