I have read several threads that say "fiat will die and will be replaced with crypto" as you agree? I personally do not agree. because when the real system is already established in value and a new system comes with a fluctuating value, the government will not take that risk. But do you agree if Fiat collaborates with crypto in building a future financial system? without killing one system. share your opinion about this.
When we say collaborate, each party hold the same share. However, this collaboration cannot be possible. Rather, a working system between the two must exist. For an economically-stable country, which has a government different from others, and those which undergone a drastic history and rich culture, fiat as legal tender is the main and only form of currency. If they/we are to employ crypto, it could be a second, third or even fourth form of currency. Besides, crypto and its branch underwing functions differently. So I think the way to be able to legally use crypto for international relation transaction is only when trading but on a separate field - very far from fiat. But I won't think that crypto can never ever function with fiat. This just actually needs trial and study.
