Is the L21 profitable?
Not at $0.08 per kWh. The BW L21 mines Litecoin and Dogecoin on the Scrypt algorithm at 550 MH/s, drawing 950 W (1.7 J/MH). At $0.08 per kWh it earns about $0.23 a day but spends $1.82 on power, so it loses $1.60 a day.
It’s #59 of 62 Scrypt miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in January 2018.
