Profitability Comparison
Antminer S9i
Nerdminer
Based on BTC price of $76,512 and current network difficulty as of May 26, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer S9i edges it: 4 of 5 factors go its way (efficacité, hashrate, score de minage domestique, niveau sonore). Where it pulls away hardest is 27999999900% more hashrate (14.0 vs 0.0 TH/s). That said, the Nerdminer isn't beaten everywhere — it still wins consommation électrique. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.

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.
| Antminer S9i | Metric | Nerdminer |
|---|---|---|
| — | Upfront cost (MSRP) | $29 |
| -$2.68 | Daily net profit | -$0.00 |
| -$976 | Net after 1 year | -$30 |
| -$1,953 | Net after 2 years | -$31 |
| -$2,929 | Net after 3 years | -$32 |
| — | 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.
