Saving our hard earned money have never been a bad idea, but their are certain things we need to consider before thinking of saving, such as inflation.
Inflation is truly the real enemy to every money that is being saved up, because when the time is right like a year time, when it should be used for it purpose, the value wouldn't be as how it actually was when you started saving it, but on the other hand, if we have been investing that money into Bitcoin, land or gold bit by bit, over the course of a year, the value of that your investment would have added additional value compared to our savings that will be eaten up by inflation.
So too me we should think of investing more of our money than saving it, so that inflation wouldn't eat it up.
In Economics, we were always taught money saved was automatically invested. Took me time to realize that it was only invested into businesses as loans taken. And what you said was true, the value would have dropped making it a vain endeavor.
So, basically what I'm trying to say is that money saved and invested are still automatically the same but we should save our money in the right place. Don't save in banks, save in assets.
