This kind of airdrop isn't the same with Google forms style. The criteria is for contributions through trading and liquidity. You need to spend a lot of gas if you wanna earn provided that it's not guaranteed.
I've just do a trade to have record for the tx simple as that. Knowing it could have an airdrop a bit later so indeed it is. Boom money printing. But those who were earlier have more tokens probably.
To be precise, instead of an old process of filling up various cryptocurrency airdrop form, you need to have an existing cryptocurrency swap that takes place on the decentralized exchange aggregator? So in this case, I only need to have a total of 20 USD worth of trades in order to be eligible for 1inch tokens isn't it? I've also noticed that this is something similar to the UNISWAP exchange where I traded some of the ICO token I've received last month.
It's pretty rewarding especially for those people who created and connected a bunch of trust wallet in their exchange.LOL
