It is important to invest, when the investment has great potential. But I think it is a good decision to also have reserves, because you may it need in the future and this can make a difference.
I think if in order to choose which one is an important advance of investing or saving both are equally important. but the most important thing of course is to save because you can become rich store of income that you get. investment is only as a sideline. you can still become rich even without investment
Investment is risky if you are invest in ponzi site or any site with promises converting money in to bitcoin can be considered as investment..
Saving money into the bank is one of the safe. but you can also invest in banks but the interest is low and every year you can see the profit.. unlike you invest your money into bitcoin and wait in few months if the price of bitcoin is high you can sell it and get profit.
So for me both have a good.
