it is good for investing but not for transacting, because the price is not fixed so we as owners can feel a loss if bitcoin is in a period of correction,
and I'm not sure all countries accept the existence of bitcoin cs, into their government, because fiat is easy to regulate even though it always results in inflation
I do agree with you on that and not only during market correction but because of that volatility when you spend Bitcoin on depreciating assets, it seems like you have waisted that amount of Bitcoin cos I remember a post some week ago about some investors buying an iPhone with Bitcoin and even when most think it was good news that Bitcoin was been accepted in many retail shops now but most believed that asset has a depreciating value compared to Bitcoin so, Fiat is still good in terms of daily transactions while I do appreciate my Bitcoin more as an Investment.
