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-K1 | Metric | Goldshell KD5 |
|---|---|---|
| $9,855 | Upfront cost (MSRP) | $1,998 |
| -$1.81 | Daily net profit | -$4.75 |
| -$10,517 | Net after 1 year | -$3,733 |
| -$11,179 | Net after 2 years | -$5,467 |
| -$11,841 | Net after 3 years | -$7,202 |
| 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.
