Even the central bank digital currency is the same as the Fiat, all of them are all about inflation: as the government continues to print more paper money the value is going to decrease, and this will also affect the central bank digital currencies because they are tagged to the Fiat.
Right from time, Fiat has never been a better option to hold, if you are using fiats for your savings or as an investment then you are just going to be losing, because it’s of no use. Yes I do know fiat is important because we use it on a daily, but it shouldn't be bad to try and invest in other things such as Bitcoin and other stocks like gold and the rest of them. This is very important if you would like to save your value in future.
Yes I do agree that saving fiat is useless since it loses value over time. Its better to invest your fiat into something that increases its value over time like real estate, equity etc. There is risk factor involved in such investment that must be taken into account. One more thing I wanna add is that concept of fiat has also find its place in crypto in the form of centralised currencies like xrp, bnb etc.
