I am not sure if the national bank will release its own crypto, because so far there are many national banks that continue to contradict cryptocurrency, although it does not rule out the possibility that many countries that support crypto like Japan will implement it.
By the way, do you want to live in such a world? I do not want to live in such a world that I can be monitored by the goverment, no matter how convenient it is.
I personally don't mind living like that monitored by the government, because I feel enough concern if I have to deal with the bank, because the funds I get are almost completely and more than crypto. So if the government and bank will release their own crypto, then that is a very good step I think because I as a crypto user no longer need to worry about something, because so far national banks in my country are still opposed to cryptocurrency.
Well, that is something that is still a mystery for now, but I believe in the long run, this is something we will get to start seeing gradually with government and central banks utilizing the blockchain by integrating fiat on it.
We know the world is gradually going digital, so there is no doubt, that at some point in the long run, we will have the governments all over the world, coming up with their own centralized digital currencies, which would probably eradicate paper currency anyway and then we will at least be able to get to see things done different. Nonetheless, it does not really make that much of a difference at the end because it will still be controlled.
