I think it's very good to invest it because saving money will only make our loss if inflation happens, but if we invest it like buying a real estate or bitcoin we will not be exposed to depreciation of assets due to inflation 
For me, both saving and investing money are good for future use but the only difference is there are more chances to multiply or much more than the quantity of the money being invested while saving money like for an example of keeping it through the bank is just only have low interest compare from another one being mentioned.
