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.
There are several prepaid debit card services which convert your bitcoin into fiat for use it anywhere for withdrawing money from ATM or using it where Visa debit card is accepted. Famous services in my knowledge are Cryptopay and Bitpay cards. Actually you are not paying purely in bitcoin using these cards , your bitcoin are converted into dollars or other paper currency for use.
