Funny, yeat all bitcoin debit cards are MasterCard...
I think Xapo is using VISA. Maybe other Bitcoin companies should switch to VISA or other companies if MasterCard doesn't like that kind of business.
Well, truth is that it isn't that hard to issue a specific debit card if you have a company. IMO the business of bitcoin reloadable debit cards isn't all that huge for mastercard but it's not like they're going to lose their costumers over a statement.
