If you are young you should be investing more than you save.
Investing had nothing to do with you age apparently . What matters is your financial management if you are choosing to invest instead of saving it. Without it then you are bound to fail no matter how big your capital or how old/young you are.
no risk savings but ideally with interest if possible but good savings interest rates are hard to find compared to years ago.
As a matter of fact, savings in a bank is actually a loss for yourself because the interest rate will always be lower than the yearly inflation rate. That is a risk because in the end the FIAT that you hold could be "worthless" due to inflation and safe deposits could be an answer for that if you are willing to give away the ability to move your FIAT around , the gain of the interest may not be as big as investing your money however it is much more safer .
As for the bolded part, the interest rate were never always the same IIRC and most of the saving interest rate were always below inflation rate (depending on the country inflation rate though)
