I’ve been trying to understand profitability by looking at the whole operation rather than just the number of coins earned. There are equipment expenses, electricity costs, mining performance, upgrades, and other variables that can influence the final result. Sometimes a change that looks impressive in one statistic has a different effect when you look at the overall balance afterward. I actually enjoy this part because it turns the game into a little numbers experiment. You can make a change, let the simulation run, and then compare what happened. If you like that kind of gameplay, I’d recommend the crypto-mining simulator on https://rollercoin.com/free-pepe-coins . It’s a surprisingly entertaining management experience, especially when you start paying attention to how small changes interact instead of treating every upgrade as an isolated improvement.
