Is it better to save money in bank or invest it online, in real estate or maybe gold?
Save your money and investing are two good things, but if you do not need the money now, I advice you to invest in something profitable.
With Bitcoin, you can save your money and invest at the same time, since the price of Bitcoin change much.
Like in what kind of investment that something profitable? Are you talking on a deal with fiat here or in bitcoin?
Well you need money that's why you invest.

Much better if the term is, if people like to maximize their earnings, they can go for an investment whether on real life or online.
