Saving money will really not bring any profit and your money value will be less in the years to come so investing and making your money grow more is the best solution to make profit more.
You will get profit if you just buy bitcoins with your money and hold it halving is to be happened soon so the price will increase . You will get an easy profit.
But it is risky than just save it, although money value always decrease, bitcoin price can decrease too (and it decrease more than money value). So you need to save some instead of invest all
Investing is nothing but not investing everything what you have money with you and also it is not safe to invest all your money in any one or two products. From your regular saving you should invest some portion of it and also diversify your investments to reduce risks. I choose to invest in real estate, gold, shares and some money in bitcoins. I chose bitcoins because its prices are more volatile and can make some profits easily but now a days the prices are very stable so it is difficult to make profits from bitcoins trading.
