Spec Deltas
Stripped to the numbers, this is how far apart the iBeLink BM-K3 and iBeLink BM-N3 sit on each measurable spec:
- iBeLink BM-K3 180% more hashrate (70.0 vs 25.0 TH/s)
- iBeLink BM-K3 64% better efficiency (47.1 vs 132.0 J/TH)
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-K3 | Metric | iBeLink BM-N3 |
|---|---|---|
| $820 | Upfront cost (MSRP) | $980 |
| -$5.40 | Daily net profit | -$7.02 |
| -$2,792 | Net after 1 year | -$3,543 |
| -$4,764 | Net after 2 years | -$6,105 |
| -$6,736 | Net after 3 years | -$8,668 |
| 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.
