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.
Exactly, for example if i have one bitcoin and i just keep it in my wallet without using it anywhere for investments or etc, and after some time the price of bitcoin drops some percent, so in that case the money i had before would be less now, in order to prevent this thing we need investments which would keep increasing our assets with the time.
