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 her 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.
