Profitability Comparison
Bitaxe GT
Holic H28
Based on BTC price of $64,000 and current network difficulty as of Jun 4, 2026. Actual results vary.
Verdict
Selon notre analyse multifactorielle, le Bitaxe GT l'emporte sur 4 des 5 facteurs (efficacité, consommation électrique, score de minage domestique, niveau sonore). Its biggest concrete edge: 96% better power draw (75.0 vs 2,100.0 W). The Holic H28 holds the edge in hashrate. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Bitaxe GT and Holic H28 diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Holic H28 460% more hashrate (5.0 vs 28.0 TH/s)
- Bitaxe GT 96% better power draw (75.0 vs 2,100.0 W)
- Bitaxe GT 80% better efficacité (15.0 vs 75.0 J/TH)
- Holic H28 2700% more heat output (256 vs 7,165 BTU/hr)
- Bitaxe GT 146% more score de minage domestique (64.0 vs 26.0)
Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Bitaxe GT | Metric | Holic H28 |
|---|---|---|
| $499 | Upfront cost (MSRP) | — |
| -$0.04 | Daily net profit | -$4.23 |
| -$512 | Net after 1 year | -$1,544 |
| -$525 | Net after 2 years | -$3,087 |
| -$538 | Net after 3 years | -$4,631 |
