OK... that means there is no way of getting the money back. It is probably because the Bitcoin is very untraceable and volatile still.
BTC is irreversible once confirmed, PayPal is reversible up to 180 (or even 365) days in
every case. No friends and family, no other option will help you against that.
A notable read is also what spoetnik has to say to the topic:
PayPal unlike many other services forbids the use of digital currencies. They have been seizing accounts for years. it happened to me.
When i google searched the email Paypal sent me i seen a guy post the same one here back in 2012. It's not chargebacks you need to be worried about it's simply forbidden!
and THEY WILL seize your account and take money. Avoid PayPal with Crypto or suffer the consequences.
