Is the Antminer G2 profitable?

Not at $0.08 per kWh. The Bitmain Antminer G2 mines Ethereum Classic on the Etchash algorithm at 220 MH/s, drawing 1,200 W (5.5 J/MH). At $0.08 per kWh it earns about $0.09 a day but spends $2.30 on power, so it loses $2.22 a day.

It’s #39 of 39 Etchash miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in December 2017.
