I agree with your opinion that the bounty campaign brings more profits than airdrop. Airdrop requirements are very simple. I also follow and joined airdrop, most of the tokens values are very small and sometimes there is no market, besides that I also avoid airdrops that ask for KYC, because in my opinion it's not balanced, our personal data is used to get a little token. So, i join airdrop and bounty to get more money.
