Sorry if the topic sounds logically flawed I didn't dig much deeper into the financial fantasies of such.
I'm wondering what if one day Bitcoin goes so high up in value that it causes somewhat a fiat crisis? I mean imagine, you've Bitcoins but there isn't much cash available in the market to buy your BTC, or simply put people can't afford it? Will bitcoin be of any value then?
Bitcoin undoubtedly has a very high market price in the market and high value than fiat money. But fiat money is just the main currency that can be used in a country.
It might not cause any impact since the market price could always continue to increase, and if you want to spend it the best thing to do is convert it first to a fiat since bitcoin was not yet accepted in some countries or stores. So the value of the fiat would just depend on the country that is why different fiat currency has a different value.
In the future, it might be a digital transaction that could be our future or could even be crypto but I guess it was just an improved version of fiat money.
