PayPal is one of the riskiest payment methods and a favorite of scammers. Ask for ID with selfies and signatures and check for photoshop. http://fotoforensics.com/ It is best to call PayPal and tell them you are selling bitcoin as they allow it.
I would prefer to pay with PayPal credit but can also purchase with debit. PayPal credit is guaranteed money for you! I am not using my credit card, I am using PayPal credit, a credit offered through them, the purchase is basically guaranteed.
