Profitability Comparison
iBeLink BM-S1
iBeLink BM-S3+
Based on BTC price of $73,473 and current network difficulty as of May 30, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the iBeLink BM-S3+ edges it: 4 of 6 factors go its way (efficacité, hashrate, score de minage domestique, niveau sonore). Where it pulls away hardest is 268% more hashrate (6.8 vs 25.0 TH/s). That said, the iBeLink BM-S1 isn't beaten everywhere — it still wins consommation électrique and rapport qualité-prix. Review the detailed specs and profitability calculations above to determine which miner best fits your specific setup.
Spec Deltas
The iBeLink BM-S1 and iBeLink BM-S3+ diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- iBeLink BM-S3+ 268% more hashrate (6.8 vs 25.0 TH/s)
- iBeLink BM-S1 31% better power draw (2,350 vs 3,400 W)
- iBeLink BM-S3+ 61% better efficacité (346 vs 136 J/TH)
- iBeLink BM-S1 36% better weight (9.0 vs 14.0 kg)
- iBeLink BM-S3+ 45% more heat output (8,018 vs 11,601 BTU/hr)
- iBeLink BM-S3+ 38% more score de minage domestique (26.0 vs 36.0)
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 | iBeLink BM-S3+ |
|---|---|---|
| $768 | Upfront cost (MSRP) | $3,299 |
| -$5.41 | Daily net profit | -$7.33 |
| -$2,744 | Net after 1 year | -$5,974 |
| -$4,720 | Net after 2 years | -$8,649 |
| -$6,696 | Net after 3 years | -$11,324 |
| 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.
