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.
| Antminer KS3 | Metric | Bitmain Antminer S23 Hyd |
|---|---|---|
| $8,000 | Upfront cost (MSRP) | $12,995 |
| -$8.06 | Daily net profit | $7.88 |
| -$10,941 | Net after 1 year | -$10,118 |
| -$13,882 | Net after 2 years | -$7,240 |
| -$16,823 | Net after 3 years | -$4,363 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~4.5 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
