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?

Also, I don’t think history of selling matters. The previous products could have been shitty products. 

And sending people free money not tied to an activation requirement is just stupid marketing. 

I’d rather target users who have:

High onchain transaction volumes 

High propensity to try new onchain  products

You keep avoiding the question — all else equal, which do you pick?

Flawed question to begin with.
If said airdrop is, let's say a governance token. 
To your everyday user the governance token Is useless. 
Build the product and give them a reason to hold it and a use case. 
You can clearly see in every single governance airdrop that has existed so far. Not one token reaches ATH ever again. The cabal controls the voting. Unfortunate truth but airdrops have failed in every sense. Governance tokens haven't delivered what it was promised and with current market mentality can't fault people for selling.
