Is the Antminer L11 profitable?

The Bitmain Antminer L11 (20G) mines Litecoin and Dogecoin on the Scrypt algorithm at 20 GH/s, drawing 3,680 W (184 J/GH). At $0.08 per kWh it earns about $12.04 a day, spends $7.07 of that on power, and keeps $4.97. That’s around $149 a month. It stops making money above roughly $0.136 per kWh.

That puts it #48 of 522 on daily profit across every miner we track, and #8 of 60 Scrypt miners on efficiency. At the current best price of $6,621 it would pay for itself in about 3.7 years if today’s numbers held. They won’t, so treat that as a rough guide. It’s an air-cooled unit, released in September 2025.
