It is like who will kick the ball first but even with that, the possibility of it taken over is not seen yet in my view and one reason is because of its decentralized nature. Many country won't want their identity to be eroded.
the clearest and most obvious is the time that will answer all this, will the digital currency take over the finances in the banking or, alternatively, the government and the bank take over and control the digital currency becomes centralized.
I think moving to digital currencies is a right way because it saves many and it is easier to use in today’s situation but normal currency are also very important but need to move on so digital currencies are the right decision.
