These are ways we can easily use money wherever we have such necessity. But to save them we have to do more than just keeping them in fiat. Because fiat money is not a reliable asset, it tends to inflation or deflation, it also inclined to be destroyed or blocked or lost. And you cannot be sure, that you will have access to it, when you need it. That is why you should concider other ways precisely for saving, and it can be investing included.
If you remember that current economic conditions still tend to change and have not fully improved, it could indeed be very good if you consider saving in other ways besides saving money. But this option to save in other ways is only often used by investors who want to save the value of their assets into stablecoins besides continuing to invest in property and Bitcoin. Whereas people who don't like investing in property and Bitcoin will make their savings through gold if they don't like saving money in cash in their lives because of inflation or deflation that can arise at any time.
