How much do airdrop farmers make?

The weirdest thing about crypto is nobody (tmk) has earnestly studied this economy.

I believe if there are any studies, we would see a lot less people engaging in farming. 

1. Those with more financial resources can generate a higher volume and, therefore, earn greater rewards, especially if the airdrop is based on volume metrics like dydx, blur or opensea. 
2. Individuals who know how to use bots for farming can also make money effectively with projects like zksync optimism or other L2s. 
3. However, normal users might be making less than minimum wage. While there may be a very few projects which might pay good but most aren't worth the time and effort nowadays.
