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 S19 Pro+ Hyd. (191Th) |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $1,242 |
| -$5.15 | Daily net profit | -$5.85 |
| -$5,378 | Net after 1 year | -$3,378 |
| -$7,257 | Net after 2 years | -$5,514 |
| -$9,135 | Net after 3 years | -$7,650 |
| 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.
