Bitcoin transfers even between countries on average the administrative costs are very cheap. Obviously more profitable than banking transactions, the administrative costs of which are still expensive.
I hope that all banks can see opportunities for Bitcoin to be utilized. Although I acknowledge the central bank's concern if Bitcoin transactions are used for prohibited matters.
One step that can be done by the Bank is to allow Bitcoin transactions on condition that they have to be registered on a special platform. Later the patform must be accompanied by a central bank permit.
This means that all bitcoin transactions must be recorded by regulators, now there are many illegal bitcoin transactions without permission and without supervision from regulators.
There is one country that can use it, for example in Japan that allows transactions with Bitcoin, even for payments in retail stores.
The government in Japan actually allows retail stores to accept payments via bitcoin. There are 4,000 stores that accept bitcoin payments. So far there are no problems. Even the Japanese government is making its own cryptocurrency.
There isn't any doubt in bitcoin being better than banks in many a ways like sending the payments across the globe very quickly and cheaply than banks but the reliability and the convert ability of bitcoin to cash isn't available in most of the countries that are in the developing world so using bitcoin is almost impossible to send money into those countries. The best part about bitcoin that I like is that we get the money same day as compared to bank which takes more than a couple of days to complete the transaction.
