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.
| IceRiver KS1 | Metric | Iceriver KAS KS0 Ultra |
|---|---|---|
| $2,500 | Upfront cost (MSRP) | $77 |
| -$1.40 | Daily net profit | -$0.23 |
| -$3,012 | Net after 1 year | -$159 |
| -$3,525 | Net after 2 years | -$242 |
| -$4,037 | Net after 3 years | -$324 |
| 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.
