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.
| IceRiver KS5L | Metric | Thewindminer K9 |
|---|---|---|
| $12,000 | Upfront cost (MSRP) | $15,429 |
| -$7.73 | Daily net profit | -$7.55 |
| -$14,821 | Net after 1 year | -$18,185 |
| -$17,641 | Net after 2 years | -$20,940 |
| -$20,462 | Net after 3 years | -$23,696 |
| 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.
