That's fine, investing will
on average yield bigger returns (higher rewards) compared to saving. Nobody would invest if this wasn't the case. Investing in and of itself is a good thing.
What you are all seemingly misunderstanding is that I am saying you should not invest money that you don't want or can't afford to lose.
Yes, money deposited in savings might not (and probably will not) keep pace with inflation, but you are guaranteed that you will be able to always take out as much as you deposited. If you deposit $50,000.00 you will always be able to withdraw $50,000.00. Yes, inflation might have reduced the purchasing power of that money to $30,000.00 or whatever when it's withdrawn, but that is not the point: You can always withdraw the $50,000.00 that you deposited.
Meanwhile, if your investments go south you lose money. If you invest $50,000.00 into stocks or crypto or whatever, you aren't guaranteed you can get back at least $50,000.00. It could be $100,000.00, it could be $10,000.00, or it could even be $0.00, but in any case you aren't guaranteed a floor of $50,000.00 in returns. You can (and will) both gain and lose money in investments.
This is why I am saying people should not be using their savings (or even life savings?!) for investing. This is ostensibly money you do not want or cannot afford to lose, this is not money you should be spending on investments.
Invest with money you are okay losing, otherwise you will regret it.
