Profitability Comparison
Antminer L9
Elphapex DG2 Mini
Based on BTC price of $78,165 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer L9 edges it: 3 of 6 factors go its way (efficiency, hashrate, price-performance). Where it pulls away hardest is 567% more hashrate (0.0 vs 0.0 TH/s). That said, the Elphapex DG2 Mini isn't beaten everywhere — it still wins power consumption and home mining score and noise level. Cross-check the spec deltas and ROI table above against your own electricity rate before deciding.
Spec Deltas
The Antminer L9 and Elphapex DG2 Mini diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":

- Elphapex DG2 Mini 70% better weight (14.8 vs 4.5 kg)
- Antminer L9 534% more heat output (11,464 vs 1,808 BTU/hr)
- Elphapex DG2 Mini 61% more home mining score (36.0 vs 58.0)
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.
| Antminer L9 | Metric | Elphapex DG2 Mini |
|---|---|---|
| $6,500 | Upfront cost (MSRP) | $999 |
| -$8.06 | Daily net profit | -$1.27 |
| -$9,443 | Net after 1 year | -$1,463 |
| -$12,386 | Net after 2 years | -$1,927 |
| -$15,329 | Net after 3 years | -$2,392 |
| 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.
