Bitcoin is going to be "embraced" by the existing institutions exactly as the article says. I don't think there will be any kind of crypto "overturning" of the existing systems unless there is suddenly a massive desire for cryptos to overtake the current fiat system by the general population of most countries. Banks will likely prevent this from happening by turning cryptos into assets, ideally to dissuade people from trying to take cryptos on as the primary payment medium. This is furthermore emphasized by the moves of stockbrokers to implement crypto trading markets on their respective platforms. The blockchain tech might be used by banks in the future for some transaction purposes, but I think that's as far as crypto will get within the traditional banking communities.
