A dedicated Bitcoin bank is hilarious. I have 3 dedicated Bitcoin banks sitting in my living room called wallets.
A more appropriate term would be dedicated Bitcoin exchange.
Yeah, the only difference is that the "bank" is for many people.
You mean like a web wallet such as blockchain.info where many people store their coins? The only difference I see is you don't know what a bank is and are confusing it with an exchange.
Did you even read the article? They are not a bank.
