Tittle is misleading, good news but misleading.
Yeah, we are not quite there, bitcoin should be fully integrated into ebay, there is really nothing preventing this except politic.
Bitcoin is
perfect for ebay.
Actually bitcoin would make it very easy to scam on ebay. In order for the buyer to be sufficiently protected when buying on eBay the buyer needs to have the ability to dispute the sale within a certain amount of time if the product they buy does not arrive or is defective.
Also you can use whatever method of payment you want to and the seller agree to when you buy something.
