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-N3 | Metric | Goldshell CK5 |
|---|---|---|
| $980 | Upfront cost (MSRP) | $998 |
| -$7.02 | Daily net profit | -$5.33 |
| -$3,542 | Net after 1 year | -$2,943 |
| -$6,105 | Net after 2 years | -$4,888 |
| -$8,667 | Net after 3 years | -$6,832 |
| 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.
