are there any new rules on ebay to protect seller and buyer? I wasn't able to find anything about this!
No, there is no update, and there will never be bcause main problem isnt "blockchain", it's paypals rule that "customer" is always right. I felt it on my own skin. Guy gough BTC, i delivered, and than he clamed that he does not recognize transaction, that his account was probably hacked, and he got his money back and i lost my BTC.
Basicly, scam is not "oh noh i didint got my BTC", it's "OMG my credit card / paypal account got hacked, pls return my money" and there is nothing we can do. It's happening all over the ebay all the time, not only BTC, and in 99 oit of 100 cases beay / paypal sides with buyer. As simple as that. When you deal with PayPal, calculate certain percentage of this into your price and youll be good.
Well it's just a matter of willing...
If paypal recognize as 'sent' the transactions of the blockchain where there is the proof of delivery from address A to address B where every passage is tracked and approved by many poeole, there couldn't be any problem.
Could be considered like a phisical object and tracked like a courier could with a pair of shoes... can they say: "OMG my credit card / paypal account got hacked, pls return my money even if i bought this pair of shoes?" ... They ask the seller the proof of tracking, like could be done with cryptocurrencies... even easier in this last case since, the proof will be there forever online and won't disappear after few months like any courier database.
As said is just a porblem of willing, if they don't intend to, they'll never do it even if it could be the safest sysytem of the world...
If they used that method, I feel there would still be problems with giving the buyer and seller the correct BTC address. Still many ways to scam new buyers and sellers. I'd prefer eBay to just act as an escrow and release the coins after payment. Seller is guaranteed payment and eBay deals with disputes and chargebacks.
I've said many times PayPal bow down to CC chargebacks. And chargebacks usually will side with buyer. That's just how it works. I really doubt there's a BTC specialist to investigate these claims. I don't deliver BTC unless I'm 95% confident the buyer won't chargeback.
On the bright side, you don't have to worry about PayPal reversing or closing your account for selling BTC now. That's half the battle. Chargebacks I can usually deal with.
