ok but for the customer, what is the actual use case. the customer doesnt pay fees when using a credit/debit card. the target audience of this feature is people who understand bitcoin but dont want to pay with it, paying a merchant who primarily wants to accept bitcoin. what's the addressable market? a few thousand people, maybe?
