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.
| Antminer K7 | Metric | Bitmain Antminer T17 (40Th) |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $155 |
| -$5.08 | Daily net profit | -$3.82 |
| -$5,353 | Net after 1 year | -$1,550 |
| -$7,206 | Net after 2 years | -$2,945 |
| -$9,060 | Net after 3 years | -$4,340 |
| Does not pay back at current rates (negative daily profit) | 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.
