Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| iBeLink BM-KS Max | Metric | iBeLink BM-S1 |
|---|---|---|
| $1,799 | Upfront cost (MSRP) | $768 |
| -$7.77 | Daily net profit | -$5.40 |
| -$4,635 | Net after 1 year | -$2,739 |
| -$7,472 | Net after 2 years | -$4,710 |
| -$10,308 | 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.
