Only time will tell. I don't see much sense in the JPMorgan Coin. I don't think other banks will accept it.
Of course you don't. There's a huge misunderstanding of what it is on tech forums (which I find quite surprising, to be honest).
This is not a public coin, like bitcoin. You won't be able to buy it and sell someone. We won't be mining it. I doubt it will actually be visible to clients in any way.
It's just an IT solution that JPM will use internally. They're simply implementing a distributed ledger. 1 "JPM coin" will be worth 1 USD.
Why are they doing it? That's pretty simple.
When you transfer money to another person/account in the same bank, it can happen instantly. It's an internal operation.
When you transfer money to another bank, it has to go through an inter bank transfer system. That's why these transfers take at least few hours in the same country and usually at least a day between countries.
Remember JPM is a global bank. However, their offices in different countries are technically separate banks with separate books (even if they're all on the same server).
So every transfer has to go via the inter bank systems.
What will change, is that JPM will be able to secure the transaction based on distributed ledger and transfer money in seconds. The formal confirmation will still take 1-2 days (it'll have to go via the inter bank systems), but clients won't have to wait.
Also, this means that I, as JPM client in Poland (and I'm thinking about it), can open an investment account in JPM USA, that I'll use for investing on NASDAQ. So I'll be able to transfer money instantly and make instant operations (which makes intra day trading possible).
How this work today is: I can either have everything in US (which means I have to keep my money there, in USD) or I can invest in NASDAQ from my broker in Poland, but I pay high fees and every operation takes 1-2 days.
