The best way to save money is to put in bank or to have a business inorder to exapand or to gain more profit.
I don't think so, just buy bitcoin and hold it and it will surprise you how it grows rapidly.
My brother once asked me if he should put his money in his bank account but I suggest him to invest in bitcoin so his money will have more interest than saving in bank. But he didn't believes me, and recently when he saw the bitcoin price he realized how much he could profit if he buy bitcoin and just hold it. Well, regrets are always in the end and now he learned his lesson and finally bought some and his is happy with the interest he's getting.
