why choose, aren't bitcoin and fiat as important as fiat is important for daily transactions and bitcoin is more precisely used as an asset for the future so in my opinion to choose between bitcoin and fiat depends on the holder whether to invest or to spend for basic needs.
maybe in general what you say can be said that bitcoin and fiat are equally important, I agree with that. although maybe its use and form are very different because bitcoin does not have a form while fiat is still in shape but its use is clearly the same, it can be used as a trade and exchange with what we need.
but the two are so different that it is appropriate not to make comparisons but rather to support each other. where of course there is a shortage of fiat and bitcoin can work there and vice versa if fiat is not able to do then bitcoin will be able to solve it. This is clearly a much-needed cooperation between the two.
I agree it's best not to compare fiat and Bitcoin, because I agree the existence of the two is very important and can complement each other.
As fiat is needed for small transactions, and areas that do not yet have internet access are in dire need of fiat to conduct financial transactions.
While Bitcoin can be an alternative to sending money abroad, which is faster and cheaper than fiat. Bitcoin is also very good as a store of value
compared to fiat, the conclusion is either fiat or Bitcoin has advantages and disadvantages. So it is better that fiat and Bitcoin co-exist.
