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.
FIAT and crypto could collaborate, there no way that people will immediately thrown FIAT away to be replaced by crypto. There's a lot of things to be considered first.
By the collaboration, I here pick that the mutual existence of both Bitcoin and fiat and that is already happening in economies where Bitcoin is being used. In addition, they might stay around for long without fading.
