Profitability Comparison
iBeLink BM-KS Max
Goldshell E-KA1M
Based on BTC price of $78,200 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Our scoring model gives the nod to the iBeLink BM-KS Max, which leads on 3 of 6 weighted factors (efficacité, hashrate, rapport qualité-prix). Its biggest concrete edge: 100% more hashrate (11.0 vs 5.5 TH/s). That said, the Goldshell E-KA1M isn't beaten everywhere — it still wins consommation électrique and score de minage domestique and niveau sonore. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The iBeLink BM-KS Max and Goldshell E-KA1M diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- iBeLink BM-KS Max 100% more hashrate (11.0 vs 5.5 TH/s)
- Goldshell E-KA1M 47% better power draw (3,400 vs 1,800 W)
- iBeLink BM-KS Max 6% better efficacité (309 vs 327 J/TH)
- Goldshell E-KA1M 33% better noise (75.0 vs 50.0 dB)
- iBeLink BM-KS Max 89% more heat output (11,601 vs 6,142 BTU/hr)
- Goldshell E-KA1M 56% more score de minage domestique (36.0 vs 56.0)
Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| iBeLink BM-KS Max | Metric | Goldshell E-KA1M |
|---|---|---|
| $1,799 | Upfront cost (MSRP) | $910 |
| -$7.76 | Daily net profit | -$4.12 |
| -$4,633 | Net after 1 year | -$2,415 |
| -$7,467 | Net after 2 years | -$3,919 |
| -$10,301 | Net after 3 years | -$5,424 |
| 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.
