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.
they don't like it, yet some mastercard cards are used for bitcoin business, so something is wrong about their thinking
i think with this, they just want to attract more users to use their circuit instead of visa, and they are not really discredit bitcoin
