I wouldn't even risk using PayPal right now to buy bitcoins as the payments can be reversed which means you can end up with nothing and losing out. I would look into some other form of payment instead of using PayPal especially if you are looking to not get scammed.
Well....it would be the person selling the BTC who would end up with being scammed.
I can always buy BTC from Paypal....but the question is, will there be anyone willing to sell me BTC with Paypal involved....My Guess is NO, unless the person is a novice, or trusts the buyer blindly.
