Have you ever think that Amazon may have registered those domains just as a protection against cybersquatting or similar? And it makes sense.
Yes, there is no official announcement yet from the amazon, but the good thing is once rumors keep on spreading it might trigger the amazon to really get into it. I think news are spreading to test wether there will be big demand and if majority would support once it happen. Just look at the bright side of the news, probably they are really working with it. It would be a good thing to bitcoin once amazon got started, the demand will continue to rise and probably the price also will pump.
Rumors are also saying Amazon company will develop a new crypto platform where they called amazon ethereum. This is interesting. If they start up a new crypto currency, this can rock the world! I don't think they can accept bitcoin payments.
If that's true, amazon has taken them to a new height. The crypto community will have more options. Hopefully Amazon will soon deploy this technology.
