maybe there is financial viability in banks using a cryptocurrency based system instead of current infrastructure to look after the transactions.. to enable them to mimic bitcoin in features such as international transactions. . but the transparency.. . and the philosophy . . and the very nature of the design . . . is kind of lost.. don't you think? like .. I'm sure they can come up with a better - more manipulated/able - alternative? which is what they would prefer of course. Being private profit-driven corporations. Anyway, the old money in banking will probably never understand what Bitcoin stands for. What world it shines a light on.
