I feel it's a significant step to legitimization. I wouldn't be surprised at all if that causes a bump when your skeptics and non technical folks find out they can move some spare cash into it at the very bank they've trusted with money. It's the step that opens up easy access to 24 hr international banking from people's savings accounts. And if they can't go out and spend that money at concerts or bars, they might just decide to throw it at a crypto to use later.
