This is NOT a method for getting free money / cards. You will need to refill the card with your own money.
It is for those who are either underage or don't have a credit/debit card, and need to buy somewhere where they only take cards. (You can buy games, discord nitro, subscriptions, etc.)
You can refill your Virtual Card with cryptocurrencies, paypal, gift cards, skrill, bank transfer, cash, and much more...
You can create as many cards as you want.
