This is pure rumours so please do not get your hopes up. Last year amazon registered a cryptocurrency domain name so people are wondering what it will be used for. Well how about an exchange? This could be where Amazon is heading and it would be an exciting day.
This would lead to an amazon coin similar to the binance coin. A coin that could be used for their sites from amazon to twitch. They have a lot of users for a coin and adding a market as well would give them a lot to work with.
Personally I think it would be a great idea. Crypto exchanges are making a LOT of money. And this is at today's prices. If the market cap goes up so does the value that these exchanges are making. We are talking billions of dollars from fees to help exchange them. It is a great business to get into. Amazon might want to wait for regulations to happen but once they are in place this could be a great move for them.
