Profitability in mining can be tricky, especially when factoring in hidden costs like mining pool fees, hardware maintenance, and even downtime. Those can eat into your daily profit and stretch out your ROI timeline.

I recently came across asicprofit.com, which lets you input your miner details, electricity rate, and other variables.  It gives you a more dynamic view of profitability, factoring in things you might not think of manually.

Also, keep an eye on BTC’s price—it’s such a big factor in determining ROI. A sudden drop in BTC could double your payback period, while a spike could shorten it significantly.
