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.
| Bitmain Antminer K7 (58Th) | Metric | Bitmain CK6-SE |
|---|---|---|
| $1,860 | Upfront cost (MSRP) | — |
| -$4.66 | Daily net profit | -$7.31 |
| -$3,562 | Net after 1 year | -$2,667 |
| -$5,264 | Net after 2 years | -$5,335 |
| -$6,966 | Net after 3 years | -$8,002 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
