For the past 2 years, I have spent over $20000 on gas fee to trasfer asset to dYdX. As a loyal user, I think I deserve an airdrop! But I still didnt get any.
BTW, I noticed there are quite some nice DEX derivates products coming out, such as Perpetual, Vega, Shield DAO. I have got 5000 testnet DAI airdrop from Shield DAO lately and I tried the product out. It claims that it is a risk-free pepertual contrac protocol. It seems like a pretty novel idea because it says users can enjoy an unlimited upside profit with limited downside cost--the prepaid funding fee. It might become a real hit if it manages to do what it says.
For Vega, I dont have a nice experience there so I will comment nothing. Perpetual is doing quite well so I will keep an eye on it as well.
Dydx is a DEX? Never heard of it but anyway Uniswap airdropped their tokens for promotion purpose so if the exchange you sre talking about does have any similar idea then there might be an airdrop from them.
Airdrops are useless in my opinion though.
