It's rumores ebay is gonna to start accepting crypto payments. Have u heard? I am glad that more e-commerce companies are starting to allow the use of cryptocurrency to pay. It can be assumed that Amazon and Ebay will develop their own cryptocurrency
These rumors having been going on forever and they won't stop now!
And because of eBay's buyer/seller protection program, cryptocurrencies don't sit well with their business model because reversals aren't possible which has to mean this remains a speculation!
I am sure that eBay can modify their platform and specifications in order to welcome bitcoin and cryptocurrencies to their marketplace that is if they want. As to reversal, maybe eBay can inform buyers that using cryptocurrency means no reversal. However, am sure many buyers will not welcome this idea because just like PayPal buyers must be protected with sellers not acting accordingly or maybe eBay can just select reliable sellers for this option and not make it available to all. Anyway, as long as there is that desire and the will solutions can always be found.
