Thanks for your comment.
But even IF you see it as an apple tree, you still would've had more apples by just buying them from the local farmer and then sell them when the demand for apples are higher.
The effort and cost to water and harvest your apples are just a waste of time.
Regarding the online calculator, I'm aware of this. You cant stare blindly in to them, they are just estimates. I usually add 10% error margain when i calculate.
Thanks again for your reply
But to profit I'd have to sell all apples and have no apples left. :) I'm still a very happy miner.
