Ty
Btw, I clearly understand what you but though since you explain that is only currency in those countries but not fiat which is true. To me is still spendable irrespective that can not be withdrawn or seen as Fiat it uses the same quality and same value which can be massured as normal fiat.
Yes, it is simply a way of calling each person. But I wouldn't be able to consider it fiat, because for me fiat is tied to the government and is a tool to control us, Bitcoin is also currency but it is not a government tool to control us.
Another difference is that fiat loses value over time and if you keep fiat as your currency, you will spend more money to buy something after a while, if using bitcoin, you may end up spending less buying the same product after a while.
