- iBeLink BM-S3+ 64% more home mining score (22.0 vs 36.0)
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 Max | Metric | iBeLink BM-S3+ |
|---|---|---|
| $1,250 | Upfront cost (MSRP) | $3,299 |
| -$6.55 | Daily net profit | -$7.28 |
| -$3,640 | Net after 1 year | -$5,954 |
| -$6,030 | Net after 2 years | -$8,610 |
| -$8,419 | 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.
