Profitability Comparison
Antminer L3+
Antminer L7
Based on BTC price of $78,217 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Two generations of Litecoin/Scrypt mining from Bitmain. The L3+ was the workhorse of an era, while the L7 represents a massive leap in Scrypt mining power.
The L7 is a generational leap that makes the L3+ obsolete for pure mining. The L3+ survives as a cheap used-market buy for Scrypt enthusiasts or space heater conversion.
Spec Deltas
Stripped to the numbers, this is how far apart the Antminer L3+ and Antminer L7 sit on each measurable spec:
- Antminer L7 1696% more hashrate (0.0 vs 0.0 TH/s)
- Antminer L3+ 77% better power draw (800 vs 3,425 W)
- Antminer L7 76% better efficacité (1,587,302 vs 378,453 J/TH)
- Antminer L3+ 62% better weight (5.5 vs 14.4 kg)
- Antminer L7 328% more heat output (2,730 vs 11,686 BTU/hr)
- Antminer L3+ 128% more score de minage domestique (82.0 vs 36.0)
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.
| Antminer L3+ | Metric | Antminer L7 |
|---|---|---|
| — | Upfront cost (MSRP) | $4,500 |
| -$1.92 | Daily net profit | -$8.22 |
| -$701 | Net after 1 year | -$7,500 |
| -$1,402 | Net after 2 years | -$10,500 |
| -$2,102 | Net after 3 years | -$13,501 |
| — | 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.

Frequently Asked Questions
Is the L3+ still profitable for Litecoin mining?
At current difficulty, the L3+ is barely profitable even with cheap electricity. It is most commonly repurposed as a space heater or kept as a collector item.
Can D-Central repair both L3+ and L7?
Yes. D-Central services the full Antminer L-series lineup with board-level repair capabilities.
