My thoughts on Airdrop farmers 

Airdrop farming is a very difficult niche, you can never farm enough, if you aren't careful, you will be lost in the loop.

There are a lot of projects and new ones will keep coming up, trying to catch all will put you at the Losing end.

You have to identify your strength/niche:
EVM based Airdrops 
TG Airdrops 
Solana Airdrops 
Gaming Airdrops 
Testnet and more.

Identifying this would help you prioritize and max out every drop in that niche, while trying out other ones.

Focusing on your strength, maxing them and being the top recipients is better than trying to be eligible for all and qualifying for the minimum 

Few Airdrops can make you outperform 90% farmers.

Double down on your convictions and go all in
