The best thing you can do is use a trustworthy escrow here to act on your hehalf. Dont use Localbitcoins due to the risk of a chargeback. You need to know youre 100% covered because Paypal - Bitcoin is very risky. There are plenty here who will be able to do it for you.
Yeah, I know. In this video he shows how to use PaxFul. Seems like the sellers there sends it as a gift, which makes it impossible to chargeback.
https://www.youtube.com/watch?v=UiKtw_IPD_MEven if the seller sends it as a gift/friends & family payment, they still have the ability to charge back. To my knowledge, they are able to always claim that the transaction was sent at a time that their account was hacked, and get the money charged back.
Even escrow doesn't protect you against that. Escrow only protects you against getting scammed during the transaction, not chargebacks.
I wouldn't really deal with paypal at all, if you are trading on LBC or paxful. Unless you're dealing with someone extremely trusted and has a ton of feedback, but even then, it's not risk free. Another thing that you could do is exchange bitcoin to SSL then to USD funds on Virwox. Virwox should be trusted enough, however with all their fees, I doubt it'll turn out to be a good deal.
Bestchange offers a list of exchangers with paypal. They should be trustworthy in most cases, however, you can't count on these sites to be risk free either.
