WARNING
Paypal is a reversible currency as BTC is not.
If you trade BTC/Paypal with new users there is a 99% chance that you will get scammed out of your BTC and be left with nothing.
If this user is legit he will go to localbitcoins.com or wesellcrypto.com in order to purchase BTC with his paypal.
I am 99% sure this is a scam.. I would highly advise no one trade with this "new" user. You will likely end up regretting it massively.
Not all paypal trades are scams.. But I am sure this one will be.
