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.
some people are afraid of risk, so they don't invest in BTC and letting their money sits in bank.
but they ignored the simple fact that investing it or not, their money will lose value overtime, only risky investment with high enough APR can help them beat the inflation and make profit while at it.
i'm apparently more scared of my money getting eaten by inflation than investing in bitcoin that's why most of my money 90% are in bitcoin.
for other people, they just don't think about it deep enough to justify investing in bitcoin but they will in the future when inflation goes out of control which I hope won't happen.
