Well I did not mean it in that way, but still i stand to my claim as this I have been discussing with peers too.
Firstly yes banks are not going any where agree with you. But as per the services which banks are providing let say "loan" yes there are some exchanges which offer you loans too. Then banks are giving you profits so does the exchanges. My point is Exchanges are the new type of banking not a traditional banking services but with time you will see more and more offers coming from exchanges. For example Direct merchant payments, they can be your bank guarantee they have strong KYC even stronger then some banks these days. So day by day these exchanges playing some roles in re-shaping our traditional payment methods.
