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?

If you announce Airdrop, it doesn't matter if it's user A or B. If they meet your criteria, you have to fulfill your Airdrop promise, if not, just don't announce Airdrop, it's just a marketing strategy to attract users.
