The old banking system is most likely to be discarded, now many banks around the world have turned their banking system into digital. And this is a sign that each bank is going to create its own centralised cryptocurrency so it can be regulated. Like China, which embraces the technology of blockchain to make its own cryptocurrency.

And it can be said that we know it to say goodbye to banking.
