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
maybe, but it's still too fast for that. developing their own crypto might be good, but we don't need it yet. maybe for the start it's better to use existing crypto coins like bitcoin, ethereum or even stable coins like tether.
