but come to think of it, those little amount of money that you want to be keeping as savings why not use it and invest in BTC continuously becaus that money you want to keep as savings can also be called your (discretionary income)  rather than keeping it in a bank as savings which will not bring you profit in return, why not use the money and be  buying BTC and hold it for long period of time, no money is too small to be  invest.
