- Bitmain Antminer S23 14% more heat output (10,509 vs 11,935 BTU/hr)
Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Antminer K7 | Metric | Bitmain Antminer S23 |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $4,999 |
| -$5.11 | Daily net profit | $3.05 |
| -$5,364 | Net after 1 year | -$3,887 |
| -$7,228 | Net after 2 years | -$2,775 |
| -$9,093 | Net after 3 years | -$1,663 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~4.5 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
