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 | SuperScalar K10 |
|---|---|---|
| $799 | Upfront cost (MSRP) | $5,200 |
| -$6.48 | Daily net profit | -$4.43 |
| -$3,164 | Net after 1 year | -$6,816 |
| -$5,530 | Net after 2 years | -$8,431 |
| -$7,895 | Net after 3 years | -$10,047 |
| 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.
