Although bounty is not as good as it used to be, you can still make money with it. This year I have seen a lot of successful bounty and helped bounty hunter get their reward.
Well said you hardly find profitable bounties these days due to scams and non payment In fact I had to give those tasks a break while coming back to make a thorough scrutiny on any bounty bounty before joining, while the OP thinks it quite easy to be knowledgeable in those mentioned crypto jobs not knowing that those jobs are highly skilled jobs with expertise in programming of course learning it is not an easy task can be accomplished within a shortest period of time that is why many people fall back to bounty campaigns.
