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.
Both are lifesavers.
Though the only disadvantage I could see if the majority of a certain individual is pure savings, it doesn't generate any profit, it's just there sleeping, waiting for you to spend on anything. On the other hand, investing is an active way of generating profits, depending on what kind of investment you're going to do.
For example, you're going to start a business, which most likely is not going to be good in the beginning since you have to get your daily customer first in order to generate profits and a chance to expand your business.
In short, saving is the comfort zone and risking your money in investment is a high risk high reward decision.
