ZK Nation said in the latest FAQ document that it is possible to not be eligible for airdrops even if all 7 criteria are met.

ZKsync user airdrop allocation is based on a combination of:

1. How many of the seven eligibility criteria are met;

2. The amount bridged and held on ZKsync Era (either in the user's wallet or DeFi protocol) based on the time-weighted average balance (TWAB) over the 12 months ending on the snapshot date;

3. Bonus multiplier: If the wallet is part of a predefined group, such as early ETH adopters, holders of top ZKsync native NFTs/tokens, or holders of airdrops such as ARB, OP, ENS, etc., it will receive an allocation multiplier.

Therefore, trading volume itself has no impact on the size of the allocation.

This means that even if you meet all seven criteria, but your average holding amount over a period of time is small, or you are not eligible for any other bonus multipliers, you may not be eligible for a distribution.
