In my opinion, Bitcoin is not suitable to be the national currency of a country. Looking at all the ups and downs of its price, Bitcoin’s volatility is too high and too dynamic. Such sharp fluctuations on the scale of a country’s economy can lead to serious risks and instability, which is too risky for maintaining the standard of living for the people. Therefore, Bitcoin is good as an asset, but it is not suitable as a national currency.
The incompatibility depends a lot on the conditions of a country because we know El Salvador has done this and they have something that can be an example for other countries.
But to go further we need to test the level of suitability because each country has its own currency so deciding to accept bitcoin as an official currency will be quite risky.
This is the challenge and may be difficult to realize because changing regulations and accepting bitcoin as an official currency is not an easy thing to do.
So not all countries may be able to implement what El Salvador did because there are many things that need to be prepared.
In addition to talking about volatility or fluctuations that are so sharp.
