In addition to that, PayPal can freeze the account if they think the person is trading and purchasing cryptocurrency (I believe)
I don't think so , because one i was charged back with a scammer Kralle and i had to explain stuffs why he Charged back and if he was Genuine and clearly mentioned Them the Txn id of Bitcoins and Screenshots of Conversations on BT .
Even each time now i transact i Specifically tell the buyer to mention the amount of Bitcoins and transaction in Paypal noted .
I have been dealing with Bitcoin-Paypal and never got any problem from Paypal side.
