I'm not really familiar with how VISA/MasterCard work, but I'd like to know if there's a way to use them and pay in bitcoin or any other crypto currency. My main interest is paying for exams/application fees for my post graduate studies, so small limit on account transactions aren't a big problem.
In general, you are buying PREPAID FIAT MC/Visa card in all cases. There is no Crypto currency cards.
Then you are selling your bitcoins to the card operator and he's loading your card with fiat.
Usually cards are in Euro / USD / GBP. Keep in mind that all cards are taxing you exchange fee ~2-4% if you are paying in non-card currency.
