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.
you can use bitcoin as prepaid visa cards and many companies do this we have many chooses to use our bitcoins more than was in 2015.
limit on account isnot problem because you can get many cards and you can buy it without need to pay taxes
proble, with it is the fees you can pay about 3% of fees which is big than bticoin pay,
these cards are fast and you can do it with 10 min or less.
