This is where BTC excels.
Once it's paid, it's paid. Nobody gets to lie or manipulate any manager or customer support personnel to 'reverse' a payment since it's impossible.
Sure it has it's risks, but I'd rather take those, than risk being charged back even up to 90/180 days after a transaction happened.
You can still "sue" them... (Provided you were "smart" enough to get real information for legal proceedings to take place.)
Just as you can't "get back a dollar", after you have handed it to someone... unless you physically take it, or legally sue them for it back.
BTW, there is a "way around paypal", with two-way trust and through any third-party escrow mediator.
1: You pay the escrow-service. (bitcoins) {Confirmed by video-receipt of the "confirmed" transaction, which both of you witness}
2: They "declare/state/agree", that they are "paying for services rendered", then pay the escrow-service, or you. (paypal buyer)
3: Then they simply have to leave a review, OR send a reply to you, thanking you for the successful delivery of the "service".
4: Then the coins are sent, and confirmed by video, to the recipient. (Once confirmed, the escrow-service would then release the paypal funds, if they were held there.)
I didn't say it was "easy", but that is how you legally get around it. They are paying for a "Service previously rendered/being rendered" and they "admit they were given the service", thus, it is not "refundable", as you have the proof of delivery and satisfaction. If they "accidentally reverse the transaction", paypal will reverse it again for you, once you contact them with proof. The proof is in the paypal system, or ebay system (same company), and the addition of "recorded video transaction" by you and a witness, confirms the delivery. (The "delivery" was the service, not the bitcoins. Bitcoins was just the content of the delivery, and irrelevant to the "service". EG, like postal delivery. You pay for the delivery, not the contents of the package, from the post-office.)
Obviously, selling to a stranger is just, dumb... based on "nothing", since "trust" is not there. This removes the "stranger", and adds "trust". For the most-part... (Still, anyone can provide fake credentials, or still be scamming, or "make other claims"... (BTW, if both parties attempt a "reversal" and both dispute the owner, then paypal simply locks the money, and only releases it after a "court order" pending a trial and "clear winner".) Thus, the "buyer/seller protection" they offer, and YOU agree to, on every purchase you make.) Banks do the same thing also.
