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.
| Bitmain Antminer KS5 (20Th) | Metric | Iceriver KS1 |
|---|---|---|
| $799 | Upfront cost (MSRP) | $199 |
| -$6.48 | Daily net profit | -$1.40 |
| -$3,164 | Net after 1 year | -$711 |
| -$5,529 | Net after 2 years | -$1,224 |
| -$7,895 | Net after 3 years | -$1,736 |
| 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.
