what range would you say is reasonable for this purpose. e.g. from case 1: -10% anual return to 5: 50% anual return (just as example, not what I am using now).
What range would you use and why?
I don't think there is limit to how we can earn from our investment in Bitcoin, once we have the tenacity to invest and hold for some time till it becomes more profitable for us to sell, in my own case, any percentage is fine and ok by me, as long as am going to break even from it, once am not at loss, anything should be a profit except if am being greedy or something else.
