Honestly, I have not done airdrops for a long time and it is difficult to remember which airdrop brought me the most money, but there was a lot of airdrops that brought to me 100-200$ each and I remember one airdrop that brought me 1k$, but I forgot name of this project which gave me 1k$ and so I'm sure that most people who do airdrops got the most from UNI airdrop, unfortunately I not received UNI.
