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.
| Antminer KS5 | Metric | SuperScalar K10 |
|---|---|---|
| $12,000 | Upfront cost (MSRP) | $5,200 |
| -$6.48 | Daily net profit | -$4.43 |
| -$14,365 | Net after 1 year | -$6,816 |
| -$16,731 | Net after 2 years | -$8,431 |
| -$19,096 | 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.
