It's highly unlikely that you can become rich with bounty campaigns these days. Remove that mindset and start working on something that you can enrich with the skills that you had right now.
I think the days where you can get rich just from bounty are over, but you might be lucky to find a new project that gives away a lot of coins and those coins start to moons, months or even years later. That's a way to earn crypto.
Most airdrops are a waste of time just like faucets are.
But in crypto you never know, the work that pays a few dollars in crypto today might turn out be worth a lot of money in a few years from now.
