Profitability Comparison
iBeLink BM-K3
iBeLink BM-S1
Based on BTC price of $76,909 and current network difficulty as of May 18, 2026. Actual results vary.
Verdict
Based on our multi-factor analysis, the iBeLink BM-K3 wins on 3 of 5 factors (efficiency, hashrate, price-performance). The standout gap is 929% more hashrate (70.0 vs 6.8 TH/s) in the iBeLink BM-K3's favour. That said, the iBeLink BM-S1 isn't beaten everywhere — it still wins power consumption and home mining score. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
Stripped to the numbers, this is how far apart the iBeLink BM-K3 and iBeLink BM-S1 sit on each measurable spec:
- iBeLink BM-K3 929% more hashrate (70.0 vs 6.8 TH/s)
- iBeLink BM-S1 29% better power draw (3,300 vs 2,350 W)
- iBeLink BM-K3 86% better efficiency (47.1 vs 345.6 J/TH)
- iBeLink BM-K3 40% more heat output (11,260 vs 8,018 BTU/hr)
- iBeLink BM-S1 18% more home mining score (22.0 vs 26.0)
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-S1 |
|---|---|---|
| $820 | Upfront cost (MSRP) | $768 |
| -$5.44 | Daily net profit | -$5.40 |
| -$2,807 | Net after 1 year | -$2,739 |
| -$4,793 | Net after 2 years | -$4,710 |
| -$6,780 | 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.
