Is the Antminer S9j profitable?

The Bitmain Antminer S9j (14.5Th) mines Bitcoin on the SHA-256 algorithm at 14.5 TH/s, drawing 1,350 W (93.1 J/TH). At $0.08 per kWh it earns about $0.54 a day but spends $2.59 on power, so it loses $2.05 a day. It only makes money if your power costs less than about $0.017 per kWh.

That puts it #349 of 522 on daily profit across every miner we track, and #232 of 262 SHA-256 miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in August 2018.
