The above is a win because:

– they didn’t ask me anything about the amount of bitcoin I might have

– they didn’t ask to use the private key to unlock the wallet and declare the money

– they basically acknowledged that bitcoin is something else and respected my privacy

This is how precedents get set and customs are created.
