Profitability Comparison
Elphapex DG2+
Goldshell Mini-DOGE Pro
Based on BTC price of $78,217 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Elphapex DG2+ comes out ahead — it takes 3 of 6 (efficacité, hashrate, rapport qualité-prix). Where it pulls away hardest is 9900% more hashrate (0.0 vs 0.0 TH/s). That said, the Goldshell Mini-DOGE Pro isn't beaten everywhere — it still wins consommation électrique and score de minage domestique and niveau sonore. Cross-check the spec deltas and ROI table above against your own electricity rate before deciding.
Spec Deltas
Stripped to the numbers, this is how far apart the Elphapex DG2+ and Goldshell Mini-DOGE Pro sit on each measurable spec:
- Elphapex DG2+ 9900% more hashrate (0.0 vs 0.0 TH/s)
- Goldshell Mini-DOGE Pro 94% better power draw (3,900 vs 220 W)
- Elphapex DG2+ 82% better efficacité (190,244 vs 1,073,171 J/TH)
- Goldshell Mini-DOGE Pro 53% better noise (75.0 vs 35.0 dB)
- Goldshell Mini-DOGE Pro 88% better weight (16.5 vs 2.0 kg)
- Elphapex DG2+ 1673% more heat output (13,307 vs 751 BTU/hr)
- Goldshell Mini-DOGE Pro 120% more score de minage domestique (30.0 vs 66.0)
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.
| Elphapex DG2+ | Metric | Goldshell Mini-DOGE Pro |
|---|---|---|
| $8,000 | Upfront cost (MSRP) | $299 |
| -$9.36 | Daily net profit | -$0.53 |
| -$11,416 | Net after 1 year | -$492 |
| -$14,832 | Net after 2 years | -$684 |
| -$18,248 | Net after 3 years | -$877 |
| 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.
