yeah...it is very risky to transact from paypal...for me if posible i will use a paypal dummy account to receive the money then transfer to main account before sending the BTC amount.
And then PayPal pulls the money out of your main account, through the dummy account, all the way back to the chargeback.
As far as I know , PayPal never does that. The only thing they would do is take the balance from your account , If you don't have any then your balance will become negative , once you deposit an amount , It will be sent to whoever chargebacked the transaction.
Years-long veterans of #bitcoin-otc will tell you about the domino PayPal chargebacks if you don't believe this one.
Chargebacker sends to dummy account with $0 in it
Dummy account sends 100% to main account, dummy account returns to $0 balance
Main account either withdraws to bank or leaves it on PayPal balance or otherwise spends it
Dummy account with $0 goes negative
Main account either goes negative, PayPal balance is sent back to the chargebacker, or in some cases, the bank account they withdrew to is debited back to the chargebacker
