I've heard so much about how if a student applies for credit cards, it fucks with their credit score. I'd like to apply for a Paypal debit card so I can withdraw money whenever I need to..
I don't have much experience with credit cards but I do know that as long as you pay off your debt in full every month your credit will actually be good.
A debit card is not a credit card. You can only spend what you actually have. I'm not sure about the fees that paypal has so you might want to check that out.
