Profitability Comparison
Bitmain Antminer U2L9H
Elphapex DG2 Mini
Based on BTC price of $78,217 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitmain Antminer U2L9H edges it: 3 of 6 factors go its way (efficacité, hashrate, rapport qualité-prix). The standout gap is 1025% more hashrate (0.0 vs 0.0 TH/s) in the Bitmain Antminer U2L9H's favour. That said, the Elphapex DG2 Mini isn't beaten everywhere — it still wins consommation électrique and score de minage domestique and niveau sonore. 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.
| Bitmain Antminer U2L9H | Metric | Elphapex DG2 Mini |
|---|---|---|
| $3,998 | Upfront cost (MSRP) | $999 |
| -$13.61 | Daily net profit | -$1.27 |
| -$8,965 | Net after 1 year | -$1,463 |
| -$13,931 | Net after 2 years | -$1,927 |
| -$18,898 | 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.
