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 | iBeLink BM-S1 Max |
|---|---|---|
| $820 | Upfront cost (MSRP) | $899 |
| -$5.44 | Daily net profit | -$7.14 |
| -$2,806 | Net after 1 year | -$3,503 |
| -$4,793 | Net after 2 years | -$6,108 |
| -$6,779 | Net after 3 years | -$8,712 |
| 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.
