Actually I don't think JPM Coin is crypto, more like a certificate, for example, when  you go to casino, you need to exchange fiat for the chips, eventually change back to fiat. JPM Coin is most similar to that, only designed for the institutions and make the payment convenient and instant, at the end, you can also change to USD. But when it happened, it means blochchain and crypto are more and more closer between us. We can see the bright future.
