Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| iBeLink BM-K3 | Metric | Goldshell KD-BOX |
|---|---|---|
| $820 | Upfront cost (MSRP) | $330 |
| -$5.44 | Daily net profit | -$0.44 |
| -$2,806 | Net after 1 year | -$489 |
| -$4,793 | Net after 2 years | -$648 |
| -$6,779 | Net after 3 years | -$807 |
| 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.
