Who knows, while we all stand around comparing crypto dick sizes, a corp could release their own version (with a 'trusted brand name' already in place on the back of a multi million dollar marketing campaign) and a use case that does not leave the average joe confused as hell looking at a long line of random characters not knowing a private key from a wallet.
Interesting. Amazon could do this tomorrow and accept their new currency as payment for all their goods and services. If they let others use it freely it could eclipse BitCoin rather quickly. It could eclipse the GDP of some small nations rather quickly.
Amazon have the computing power, the on-line retail presence, and an aptitude for creative tax solutions. Somehow I doubt they want to be the world central bank.
