You mean "buy", right?
I'm not aware of a way to buy bitcoin with PayPal, what's CVV?
Buying bitcoin through PayPal would just be adding a third party to the process. PayPal gets your money from your bank account or debit card, right? Coinbase can do the same thing. Just go to Coinbase and get set up!
CVV is the 3 or 4 digits found at the back of your credit card right beside the white space for signature
