Since paypal is basically ebay owned and not accepted at amazon it does make sense they might incorporate a crypto as a way to attack paypal. Maybe they will launch amazon coin we will see.
Paypal and Ebay are two separate companies for a long time now. Amazon has never included Paypal because Amazon considers Paypal as a competitor directly and not directly. If you use Amazon you have noticed this company is not accepting any payment processor. They accept only Visa/Mastercard, gift cards, etc.
They have already Amazon Payment that they struggle to be adopted so I don't think they are ready to create their coin anytime soon.
If amazon will start its own coin that will not be so successful because people already have a emerging coin that gives a lot to the people and thats the main reason bitcoin is accepted by the amazon and this will give amazon extension for surviving in the upcoming era and more to it this is an ease to the bitcoin use that they can shop from amazon without any worry and in future many other stores will accept btc.
When people have a developed and well progressed coin why they will go for the amazon coin and amazon will not gain so much from that coin so accept the things as they are they made a bold decision to accept bitcoin and many other stores are following them and in future they will also accept this coin as payment and I think amazon will not do any stupidity to introduce any other coin they are making good through it.
I think this conversation is out of track, no one have mentioned that there will be an 'Amazon Coin', the thread is about will Amazon adapt Bitcoin as their medium of payment? That's it, nothing about Amazon making their own coin and stuff.
I think they are not ignoring it, they're just waiting for the right time to accept it as means of payment. But by having this transaction issues, they seem can't comprehend the time they have to wait just to confirm that transaction, so lightning network will soon fix this problem.
