It would be far better to invest your money into Bitcoin than saving it. Investment in other stocks or fiats might be good but considering the potential of Bitcoin I wouldn't put my money anywhere apart from investing in Bitcoin.
Well it would be a very good investment if you invest in btc though for me when it comes to safety of your investments, real estate would be better if you have the means to invest in one. I'd feel more secure in an investment that's tested already though time. Though again I'm not downlining the fact that having btc investment is a good, it's just that for me btc is still in an early stage right now and a lot of things can still happen
