yes indeed but the problem is it is only a rumor .  i dont think that amazon and ebay can easily support crypto payments because these two companies are highly reputable when compared to others which means they need to think and decide properly about the advantages or disadvantages of using a crypto as a payment gateway for thier online services  but we dont know if crypto trend will continue to grow day by day and many people will start to use it , for sure these can give a good impact and soon reputable companies wont not hesitate anymore to try and support cryptos  .
