I believe concepts like these can also be reapplied to cryptocurrencies, not just on fiat. The only reason why of course we aren't seeing such movement in the cryptocurrency industry is that fiat still pretty much does the work. Soon as cryptocurrencies see such notice in terms of financing if that's what you mean, provided of course that this happens exclusively for cryptocurrencies that are stable and are not fluctuating in value.
yes, that's right, but fiat can't be replaced in my opinion because there are too many regulations that bind it
bitcoin can exist without fiat if the fiat is converted into digital currency and the transactions have reached 100% in the use of all transactions in other words each country has its own cryptoccurency to remove physical from fiat and slowly replace it with cryptocurrency and use of bitcoin only for transactions international
For now, fiat is still needed and cannot be replaced, even in some countries Bitcoin is still prohibited as payment. So for Bitcoin can exist without fiat
like it still cannot happen, especially with Bitcoin which cannot be controlled by the government, Bitcoin can only be used as an alternative payment.
But if indeed in the future all countries decide to create their own cryptocurrencies, fiat can be replaced and finally Bitcoin can exist without fiat.
For this to happen, it might take a long time, because now some countries still refuse the presence of cryptocurrencies.
