This is not Bitcoin, it's a stablecoin with a guarantor.
The failure modes of DLT are going to be interesting. But the currency risk is far lower than with regular bitcoin since it's not an independent currency but is pegged to the dollar.
It's in a fuzzy gray area; it's more an accounting unit than a separate currency. The main advantage I see is that JPM does not have to spend as much on internal controls if txns are recorded in a multi-party ledger. The benefit to customers is that they could in theory trade JPMCoin with other bank customers and have some of the "programmable money" benefits of ethereum without the risk and regulatory exposure.
