I think JP Morgan will also encounter the same issues other projects have tried to tackle. That is, the price volatility of cryptocurrencies. If they back it with their money in US dollars, I think they will lose money on this. One project I'm keen on is Etharemit.org which has a different take on exchanging coins and fiat to facilitate global remittance.
it is a centralized bank created token, it might as well be the same numbersyou see in your bank account since everything about it is centralized, closed source and fully controlled by the bank! in other words it should not even be called a cryptocurrency and should not even be discussed on this forum since it has nothing to do with anything we have around here.
