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 KA3 (166Th) | Metric | Goldshell KD Box II |
|---|---|---|
| $1,399 | Upfront cost (MSRP) | $236 |
| -$1.70 | Daily net profit | -$0.78 |
| -$2,021 | Net after 1 year | -$522 |
| -$2,643 | Net after 2 years | -$808 |
| -$3,264 | Net after 3 years | -$1,094 |
| 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.
