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.
| iBeLink BM-K3 | Metric | Goldshell KD2 |
|---|---|---|
| $820 | Upfront cost (MSRP) | $828 |
| -$5.40 | Daily net profit | -$1.78 |
| -$2,792 | Net after 1 year | -$1,476 |
| -$4,763 | Net after 2 years | -$2,125 |
| -$6,735 | Net after 3 years | -$2,773 |
| 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.
