Profitability Comparison
iBeLink BM-K3
Goldshell KD-BOX Pro
Based on BTC price of $76,892 and current network difficulty as of May 18, 2026. Actual results vary.
Verdict
Our scoring model gives the nod to the iBeLink BM-K3, which leads on 3 of 5 weighted factors (efficacité, hashrate, rapport qualité-prix). Where it pulls away hardest is 2592% more hashrate (70.0 vs 2.6 TH/s). That said, the Goldshell KD-BOX Pro isn't beaten everywhere — it still wins consommation électrique and score de minage domestique. 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-BOX Pro diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- iBeLink BM-K3 2592% more hashrate (70.0 vs 2.6 TH/s)
- Goldshell KD-BOX Pro 93% better power draw (3,300 vs 230 W)
- iBeLink BM-K3 47% better efficacité (47.1 vs 88.5 J/TH)
- iBeLink BM-K3 1335% more heat output (11,260 vs 785 BTU/hr)
- Goldshell KD-BOX Pro 41% more score de minage domestique (22.0 vs 31.0)
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 | Goldshell KD-BOX Pro |
|---|---|---|
| $820 | Upfront cost (MSRP) | $278 |
| -$5.44 | Daily net profit | -$0.46 |
| -$2,807 | Net after 1 year | -$446 |
| -$4,793 | Net after 2 years | -$614 |
| -$6,780 | Net after 3 years | -$782 |
| 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.
