I think it's a good step if amazone enters the crypto and helps raise the eth price. because I believe the role of amazon is very good and also big name amazon will definitely continue to help crypto. this is my opinion what if opinions are there all?
Remember there is a clue because amazon has bought ethereum crypto related to main at the past. Amazon will provide fast adoption to a lot of crypto users and if ethereum will be officially worked for it and then a big major bullish for ethereum will come as soon as possible. But this news needs to be confirmed by ethereum itself.
