But its Not a Myth, PayPal is covering you when somebody is trying to scam you, so i have Chosen this one for the Safety of Both
Its a well known scam and bitcoin is not covered under paypal Terms and conditions.
You come across as suspicious, I have temp red flagged you until you confirm you are using escrow and not asking for people to send first
Also what is your bitcoin address holding 5.13BTC so it can be verified (bet you wont even do this
)
