Banks will change or go under but they won't go away. They will always find some service to provide that someone else will want to buy.
Yeah true. It won't go away, maybe less bank transactions but to be totally not existing anymore ? It is very impossible . Bitcoin is there to earn extra money or to have investment but not to replace the bank eventhough there are bitcoins transactions rhat it doesn't need the bank to cash it out but then there are also lots of stuffs that bank has to do with people transactions. People need banks like banks need people to invest as well.
