I am really doubtful about your service , , you accept Paypal or just bitcoin.
I had seen in past many accounts with VCC but they all get ban soon.
I'm strongly disagree with you. Because my PayPal account is verified with a VCC and is still working until today.
I agree with you .
the verification process only once, if your card is successfully verified then you do not need to do it again. even if the card has expired will remain "verified".
