Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Bitmain Antminer S23 | Metric | MicroBT Whatsminer M3X |
|---|---|---|
| $4,999 | Upfront cost (MSRP) | $350 |
| $3.05 | Daily net profit | -$4.47 |
| -$3,885 | Net after 1 year | -$1,982 |
| -$2,770 | Net after 2 years | -$3,613 |
| -$1,656 | Net after 3 years | -$5,245 |
| Takes ~4.5 years to pay back at current rates | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
