Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| iBeLink BM-K1 | Metric | iBeLink BM-S3+ |
|---|---|---|
| $9,855 | Upfront cost (MSRP) | $3,299 |
| -$1.82 | Daily net profit | -$7.28 |
| -$10,518 | Net after 1 year | -$5,954 |
| -$11,181 | Net after 2 years | -$8,610 |
| -$11,844 | Net after 3 years | -$11,265 |
| 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.
