adding a bit more, there's an estimate for the profits to Square of adding the service:
"Credit Suisse also said that if Square can add 10 million bitcoin buyers in the next two years, which would track in line with crypto marketplace Coinbase's growth, it could drive an incremental $30 million in revenue. That figure assumes average bitcoin purchases of $200 per year and fees of 1.5%."

So the follow-up question is whether that's a realistic base of bitcoin buyers. Note the time-frame, but still 10-million is a very large number ....
