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 KD5 |
|---|---|---|
| $1,399 | Upfront cost (MSRP) | $1,998 |
| -$1.70 | Daily net profit | -$4.76 |
| -$2,018 | Net after 1 year | -$3,736 |
| -$2,636 | Net after 2 years | -$5,475 |
| -$3,255 | Net after 3 years | -$7,213 |
| 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.
