since you did your research then you obviously know that they registered domains for Ethereum as well as general domains with crypto in the name.  you also know they've had amazonbitcoin.com since 2013.  this means nothing.  anyone who thinks amazon would choose some no name crypto with no proven history over an established one is out of their mind.  

go look up amazonbitcoin.com, it's held by the amazon legal dept.  same with the other domains.  someone is just trying to hype etn.  why else would that domain not be registered to them also?  lol
