To make more profit, my advice is that you should join the bounty campaign instead of airdrop if you have time. Participating in a bounty signature will have the opportunity to earn up to $ 5,000 if you choose a potential ICO that can participate in the bounty.
I really agree with you, the campaign is better because in that campaign we can say that we work, where we will be paid according to the results and quality of our work, this includes articles or videos. if our job is good then the pay is fantastic. not like Airdrops who give away free tokens without any compensation.
