If cryptocurrencies will be the basic mode of exchange in the future, what will happen to the banks then?
This situation can be imagined but talking seriously this will never happen in reality as fiat has build faith over people and have multiple uses like its legal money and you can buy goods with it whereas it will take crypto long to get adapted in that system.The banks are all ready to face that thing and have already planned to adopt blockchain technology and issue its own digital coins.Moreover they have various services to offer whuch cannoy be overtaken by cryptocurrencies.So we will say Banks are here for long term.
