Profitability Comparison
iBeLink BM-S1
Goldshell SC Box II
Based on BTC price of $76,967 and current network difficulty as of May 18, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Goldshell SC Box II edges it: 4 of 6 factors go its way (efficiency, power consumption, home mining score, noise level). Where it pulls away hardest is 83% better power draw (2,350 vs 400 W). The iBeLink BM-S1 claws back ground on hashrate and price-performance. Cross-check the spec deltas and operating-cost table above against your own electricity rate before deciding.
Spec Deltas
The iBeLink BM-S1 and Goldshell SC Box II diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- iBeLink BM-S1 258% more hashrate (6.8 vs 1.9 TH/s)
- Goldshell SC Box II 83% better power draw (2,350 vs 400 W)
- Goldshell SC Box II 39% better efficiency (346 vs 211 J/TH)
- Goldshell SC Box II 100% better weight (9,000.0 vs 2.3 kg)
- iBeLink BM-S1 488% more heat output (8,018 vs 1,365 BTU/hr)
- Goldshell SC Box II 165% more home mining score (26.0 vs 69.0)
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-S1 | Metric | Goldshell SC Box II |
|---|---|---|
| $768 | Upfront cost (MSRP) | $379 |
| -$5.40 | Daily net profit | -$0.89 |
| -$2,739 | Net after 1 year | -$705 |
| -$4,709 | Net after 2 years | -$1,031 |
| -$6,680 | Net after 3 years | -$1,357 |
| 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.
