Maybe, but there is an intermediary, because I need to buy their tokens. So in the end it is Bitcoin > Their token > Fiat. Probably their token is not a stablecoin and can vary in price. Also, I need to register and do KYC for their service. In the end, if I would like to have 3 different cards for my family to use we would need 3 different accounts.

But thanks for your response.
