I am unable to save a significant number of coins. The few mBTCs which I earn every week from sig campaigns and other sources are immediately spend on paying utility bills and for other expenses. But still, I hope that I will be able to save a small number of coins in the future.
I think you need a plan to save and spend money, because whatever little income, if you have a plan for your finances I'm sure you could save some mbtc
I've been with that situation and I can say that you really need intensive way of managing your money. You just need to allocate it for each amount that it should be. I can say that it can be better if you will try to have some investments, because if you will just do the same routine you won't be able to prosper with that way.
