Cryptocurrency is known as the fastest transaction medium for people around the world. Bitcoin is most commonly known and used token in cryptocurrency. Suppose a country began to use Bitcoin instead of their currency. Then, what will happen?
I think forever something like this will never happen because for now even though bitcoin is one of the best things created because it can indeed be a good investment asset or as an alternative payment in some places or in some recognized countries but ultimately the purpose of bitcoin is not to replace fiat as a means of payment.
Forever bitcoin will be an alternative not as a core payment because in the end fiat will still be in full control in this case when talking about means of payment so there will be no way bitcoin can fully replace fiat because that is not the purpose of bitcoin itself.
I am personally still quite comfortable with what is the function of bitcoin now does not need to be a substitute for fiat because things like this are risky but it is enough to be an alternative for payment if it is still possible even though for me personally I still like to make this an investment asset.
