You’re a developer building a new token-based product.

Your goal is to acquire users for your product. You’re considering an airdrop as a tactic to do this.

User A 
History of not selling airdrops immediately.

User B
Sells most airdrops immediately.

You can only airdrop to one. Which one do you choose?

I’d choose User A and release each tranche at a random time within a tight window using a blockhash or other on-chain value, so nobody knows exactly when they’ll be able to sell and even User B will hold off and engage instead of dumping right away.
