well a friend of mine asked me to give my credit card details to verify his paypal account i said a no coz im not sure wat transactions he is gona do. other then that he wanted few transactions to be done frm my paypal account which are like $ 2000 or more should i really allow such huge transactions from my account. ?
Er, NO! If you use a CC to verify a Paypal account then any transactions (payments) get made from the credit card. Your so-called-friend is a scam artist. Find yourself a new buddy.
Don't do any transactions for anybody else from your account and never let anyone else use your card on paypal.
