I think people should receive airdrop depending on how long ago they started using the exchange. In terms of trading volume, it is also possible, but a lot of people (for example, me) do not have a lot of money in the crypt and all tokens will be taken by 5-10 people who have a lot of money. I, having $ 500 in the crypt, threw $ 250 of them into the ZkSync network, which is 50% of my bank. And some millionaire can throw $ 10K and it will be 1-2% of his bank. On the one hand, he supported the project more, and on the other hand, if you look at the %, then my interest is clearly greater than his. Therefore, I want the size of the invested funds not to affect the final result, because someone does not count the money, and someone is ready to spend the last on the idea
