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.
Hello, i am here to buy your bitcoins with paypal as my preferred method of payment. Just ensure your paypal is aged enough to hold the amount of funds you wish. I dont ask for your documents but if need arise i might require some. Just place your order and release the bitcoins after you have confirmed the payment. Also be patient please.
