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 don't care about what their going to do with the token, I'm paying them for attention, if my Boss pays me for work, they don't have a say in if I can / should convert my money into food. 

The wrong question is being asked here imo. 

The question or focus should be, Find me a user group that has a higher probability of continually using my product and I'll pay 10x that.

Building /veil -- ZK Privacy Protocol for Base

I've done a couple of different $VEIL airdrops for different reasons, some for exposure, some to support other projects and then some to reward usage. 

Rewarding usage has had the best results, as you get them to try the product end to end before claiming.
