The airdrop reward is very small, so if you want to have a lot of money, you have to cheat.  Besides, I think participating in airdrops is quite risky.  Airdrop programs with lots of money are often scam or dead projects.  so i think bounty is still making more money.  If you are good at writing content and making YouTube ads, I believe you will make a lot of money.  Currently, bounty projects are spending a lot of money on Content and Video.  I have seen my friend make tens of thousands of dollars when posting good videos and content for the Toko Project.
