Profitability Comparison
iBeLink BM-K3
Goldshell KD Max
Based on BTC price of $78,183 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the iBeLink BM-K3 edges it: 4 of 4 factors go its way (efficiency, hashrate, power consumption, price-performance). Where it pulls away hardest is 43% better efficiency (47.1 vs 83.3 J/TH). The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The iBeLink BM-K3 and Goldshell KD Max diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- iBeLink BM-K3 74% more hashrate (70.0 vs 40.2 TH/s)
- iBeLink BM-K3 1% better power draw (3,300 vs 3,350 W)
- iBeLink BM-K3 43% better efficiency (47.1 vs 83.3 J/TH)
- Goldshell KD Max 2% more heat output (11,260 vs 11,430 BTU/hr)
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 | Goldshell KD Max |
|---|---|---|
| $820 | Upfront cost (MSRP) | $1,320 |
| -$5.40 | Daily net profit | -$6.59 |
| -$2,792 | Net after 1 year | -$3,727 |
| -$4,763 | Net after 2 years | -$6,133 |
| -$6,735 | Net after 3 years | -$8,540 |
| 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.

Frequently Asked Questions
Is the iBeLink BM-K3 or Goldshell KD Max more profitable?
At the current BTC price and a $0.10/kWh electricity rate, the iBeLink BM-K3 is more profitable at $-5.40/day compared to $-6.59/day for the Goldshell KD Max. Profitability depends heavily on your electricity rate — use the selector above to calculate with your actual costs.
Is the iBeLink BM-K3 or the Goldshell KD Max better for noise-sensitive spaces?
Both miners have similar noise levels. Check the specs table above for exact decibel readings.
Which is better for home mining, the iBeLink BM-K3 or Goldshell KD Max?
Both miners score similarly on our Home Mining Score. Consider your specific constraints (noise tolerance, available power, heat needs) to decide.
iBeLink BM-K3 vs Goldshell KD Max: how much does the efficiency gap matter?
The iBeLink BM-K3 runs at 47.1 J/TH while the Goldshell KD Max runs at 83.3 J/TH — a difference of 36.2 J/TH. Lower efficiency means less electricity per terahash of mining power, directly reducing operating costs. In relative terms that is 43% better efficiency (47.1 vs 83.3 J/TH).
