Invest it but, wisely.
Saving money just devalues your assets over time due to inflation.
To stay ahead of the value of your assets you need to continue to grow the value.
Plain and simple.
This is true. Fiat money inflation depreciate the value of the money you are holding. So if you hold or save your money for 10 years, the current value will not be the same for the next 10 years. This is the reason why most of financial gurus advice us to invest our money in order to beat the depreciation of our money value.
