I have not traded in localbitcoins for a while but the last time I checked, some years ago, those that exchanged bitcoin or paypal asked for 100% the current price of bitcoin that is costly but taking into account all the scams I could understand why they did it, now if you are looking to sell your bitcoin for paypal probably the best place is this forum, but you need to trade with a green trusted member with a history of making those kind of trades.
