Profitability Comparison
Bitmain Antminer U2L9H
VOLCMINER D1 Pro
Based on BTC price of $78,165 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Based on our multi-factor analysis, the Bitmain Antminer U2L9H wins on 4 of 6 factors (hashrate, home mining score, noise level, price-performance). Its biggest concrete edge: 50% more hashrate (0.0 vs 0.0 TH/s). The VOLCMINER D1 Pro claws back ground on efficiency and power consumption. 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 | VOLCMINER D1 Pro |
|---|---|---|
| $3,998 | Upfront cost (MSRP) | $7,850 |
| -$13.61 | Daily net profit | -$8.40 |
| -$8,965 | Net after 1 year | -$10,916 |
| -$13,931 | Net after 2 years | -$13,982 |
| -$18,898 | Net after 3 years | -$17,047 |
| 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.
