I think they will love this technology. And they are against bitcoin right now.But maybe in the future they will want to catch it when they realize they can not stop it. Maybe they will say "yes you must use our internet banking wallet for cryptocurrency" But these are just guesswork. Thanks
Recently, very often there is information that the banking system is also beginning to implement a blockchine for its systems. But it seems to me that this is more connected with the management of the system, and not in order to attract more users .
