Saving is good but if you save it on your vault its not a wise idea because your money became stagnant and not generating a profit. Try to invest it in some king of business that will generate an income that could support you for additional family needs, just like in bitcoin if you hold it for a long period of time until the btc price will rise there is a future of good profit, you can sell it in trading altcoins. Don't dump immediatedly because there's always a good investment to wait.
Yes that type of saving is going to gain nothing much better if you are going to put your savings in time deposit to the bank because that is going to earn more interest depending on how much your money is. And when you did got profit already then you can use that for investing into other things like buying and selling of bitcoin/altcoins.
