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-S1 Max | Metric | iBeLink BM-S3+ |
|---|---|---|
| $899 | Upfront cost (MSRP) | $3,299 |
| -$7.13 | Daily net profit | -$7.27 |
| -$3,503 | Net after 1 year | -$5,954 |
| -$6,107 | Net after 2 years | -$8,609 |
| -$8,712 | Net after 3 years | -$11,264 |
| 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.
