Amazon is the leader in the retail world in many ways. This is an important decision for the crypto world. The fact that it is obvious Amazon is entering the arena is some form means that all other retailers will follow suit. The big question is does Amazon release its own token or simply start accepting the others that are out there.
At the end of the day, I believe we will end up with a situation where all tokens can be instantly swapped to pay in the currency a retailer wants. Either way, this is big news for the crypto world.
