Profitability Comparison
iBeLink BM-K3
Goldshell KD5 Pro
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: 3 of 4 factors go its way (efficiency, hashrate, price-performance). Where it pulls away hardest is 186% more hashrate (70.0 vs 24.5 TH/s). That said, the Goldshell KD5 Pro isn't beaten everywhere — it still wins power consumption. 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 KD5 Pro diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- iBeLink BM-K3 186% more hashrate (70.0 vs 24.5 TH/s)
- Goldshell KD5 Pro 9% better power draw (3,300 vs 3,000 W)
- iBeLink BM-K3 62% better efficiency (47.1 vs 122.5 J/TH)
- iBeLink BM-K3 10% more heat output (11,260 vs 10,236 BTU/hr)
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-K3 | Metric | Goldshell KD5 Pro |
|---|---|---|
| $820 | Upfront cost (MSRP) | $899 |
| -$5.40 | Daily net profit | -$6.32 |
| -$2,792 | Net after 1 year | -$3,205 |
| -$4,763 | Net after 2 years | -$5,512 |
| -$6,735 | Net after 3 years | -$7,818 |
| 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.
