Bank guy 1: "Hey guys, I've got a great idea to solve this crypto currency problem! Let's just freeze anyone's account who uses bitcoin or an exchange! It'll make their life hell and they will surely realize that crypto is not the way to go!"
Bank guy 2: "Won't that just drive all of our customers who are into crypto away from our bank and towards our competitors?? Or even worse, won't that just get them to use crypto transactions between themselves, literally forcing them to realize they have no need for banks at all????"
Bank guy 1: "Nah, it's a solid plan bro. Send that memo!!"
