We experience and will still experiencing the waves of changes and uncertainty. Will Bitcoin eventually replace Fiat currency? Why or why do you not think so?
This will not happen.
Because in any country, the only legal tender is the national currency. Without any other options. This is written in the laws of each country. No country in the world will agree to recognize a financial asset that is not under their control as legal tender. With the exception of countries willing to experiment (like El Salvador).
Fiat will be replaced by CBDC. That's it.
