- iBeLink BM-K1 8% more home mining score (28.0 vs 26.0)
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 | iBeLink BM-S1 |
|---|---|---|
| $9,855 | Upfront cost (MSRP) | $768 |
| -$1.82 | Daily net profit | -$5.40 |
| -$10,518 | Net after 1 year | -$2,739 |
| -$11,181 | Net after 2 years | -$4,710 |
| -$11,844 | Net after 3 years | -$6,680 |
| 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.
