If cryptocurrencies will be the basic mode of exchange in the future, what will happen to the banks then?
That would be the best if it happens. It would lead to the elimination of banks which are the main fraudsters. They are charging a great amount for doing anything related to money even if it means just holding on to it. It would become possible to use cryptocurrencies in daily routines easily. This would be especially beneficial for people living in far flung areas or the outskirts of the cities who do not have easy access to banks. They can then easily use cryptocurrencies at their homes as it would be widely acceptable then.
