I don´t get it, who sells bitcoins at ebay for paypal. There are a lot of scammers outside. Or do they ship a coldwallet to the adress mentioned on paypal and reload it when sucessfully shipped ?
Doesn't matter how they send it. If the buyer calls foul, they'll be getting their money back. If the seller does his homework, he can easily spot 99% of scammers on eBay. Most don't. And even if you do, there's probably a group of buyers who suffer from buyer's remorse after price dropping who will threaten you with a dispute if you don't refund them.
When I was selling on Ebay, I never sold a single BTC or lost a BTC after 50 auctions. I had a specific criteria for buyers, and they never met my criteria. Numerous scammers. I only ended up paying eBay fees for my troubles.
