Is the CK5 profitable?

The Goldshell CK5 mines Nervos (CKB) on the Eaglesong algorithm at 12 TH/s, drawing 2,400 W (200 J/TH). At $0.08 per kWh it earns about $0.94 a day but spends $4.61 on power, so it loses $3.66 a day. It only makes money if your power costs less than about $0.016 per kWh.

That puts it #458 of 522 on daily profit across every miner we track, and #8 of 13 Eaglesong miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in March 2021.
