You want to reward token holders and delegators. The reward (larger 2nd airdrop) should be proportional to the # of tokens held.
For example: if you hold no tokens, you would get no ‘bonus reward’ airdrop. If you held the initial airdrop, you would get the base reward. If you hold more tokens, your reward increases.
Intermediate selling has 0 relevance here and is a personal trading decision.
Eg, you could have sold your initial airdrop (allowing new users to enter OP governance btw) and bought back triple that initial amount now. In hindsight, that would have been the smart thing to do since your governance power increased this way. I don’t see why that should be punished.
