Bitcoin will not replace the banks it rather will be a major treat to banksters mode of operation most especially in business transactions. Because Bitcoin transaction fees for money transfer is lower than that of the banks and obtaining loans for business will be more easier with decentralize peer 2 peer networks with a lower interest rates than the banks.

So for me Bitcoin will makes those banks to reforms so that they can be able to compete favourably with decentralize networks that transacts with Bitcoin @cicbar
