Maybe they can profit if the value of bitcoin changes as the owners hold their bitcoin before selling. If you are a good businessman and also a good trader, I think you can do ideas like this. Because I've already encounter some business where they accept bitcoin as payments. Of course if they don't profit in that way, they will not use bitcoin as mode of payment or any transactions. Also less hassle for people who prefer to pay cashless which is I like since my pockets is always full, sometimes cash and sometimes trash.
