Hi Carl!
I'm in the US and we have cheap hydro-electric power thankfully, and it plays a big role in my profits. You can use estimators like on WhatToMine.com to estimate your mining setups return, but keep in mind that some currencies fluctuate earnings depending on the price per unit and it can go up and down quite a bit, even throughout the day. Thank you for following and saying that you're looking forward to the next installment: it motivates me to further continue the series! Let me know if I can help in any way, would be happy to.
