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 X5 |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $2,200 |
| -$5.15 | Daily net profit | -$3.24 |
| -$5,378 | Net after 1 year | -$3,383 |
| -$7,257 | Net after 2 years | -$4,565 |
| -$9,135 | Net after 3 years | -$5,748 |
| 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.
