Cryptocurrency and Bitcoin has bloomed since 2009, and still going upward.
Some commercial banks, including some investment banks, introduce their own cryptocurrencies for the purposes of settlements and transactions with certain financial institutions and corporations. At the moment, central banking is not interested in cryptocurrencies, but this may change in the future.
And it will definitely do.
Developed countries already involved and legalized it in their countries so other countries will follow it surely in near future and we can hope so. Till now, there are many banks in cryptocurrency and they are doing their business through cryptocurrency and still they have good position in thr global market. Many banks are thinking to involve in Crypto and many if them are planning. I strongly believe that more will come according to the people's demand, they must change their policy.
