The only way to save money is by not spending it as it's by far the easiest method one can follow ...
Or you might consider banking your money with a bank to an some interest on it.
well that is the easiest way to save money for sure, in my opinion bitcoins can have a lot of potential so i would also invest it into bitcoins
You think not spending them is the easiest way to save money, its not that, you need to spend it on basic necessities of live, it would be true if you say that don't spend on unwanted things.
