The easiest way to save money is to take a part of your salary saving in bank.
But it's not the best way. The best way is to invest something.
That is true invest on something is good enough but you need to pick a good one to invest and I think bitcoin is the good investment and give the good payout if you really maximize it. But why in other thread you are suggesting us to do saving rather than invest? That doesnt make any sense
Theres so many types of saving. You can invest your income here to bitcoin investment and in the real life you may save your salary or vice versa. And its all depend on you what are you going to do with your money.
