Probably the total number of bitcoins in the space is not enough for them to accumulate and use it as a Fiat currency for all.
The statement seems to make sense to you and maybe to majority others. But to be sincere, it does not really go down well. How do you mean that the number of bitcoin in circulation is not enough to serve a country as a currency?
Come to think of it, how many Satoshis do you think made up 1 bitcoin. Let me not stress you much, 100 million Satoshis make up 1 bitcoin. So, only 5 bitcoin can serve a country of 500 million people, if everyone is to own 1 sat, and there are about 21 million bitcoins created.
So, the argument does not hold water, because an individual does not need to own 1btc, only a few Sats in your possession would make you rich if bitcoin soar so high.
and use it as a Fiat currency for all.
Bitcoin is not fiat and cannot be used as fiat currency. It is a currency on its own.
Again, it's not upto 1 month CAR adopted bitcoin as a legal tender, why are you so quick to associate them with failure?
