Is the Antminer KS5 Pro profitable?

The Bitmain Antminer KS5 Pro (21Th) mines Kaspa on the kHeavyHash algorithm at 21 TH/s, drawing 3,150 W (150 J/TH). At $0.08 per kWh it earns about $4.74 a day but spends $6.05 on power, so it loses $1.30 a day. It only makes money if your power costs less than about $0.063 per kWh.

That puts it #309 of 522 on daily profit across every miner we track, and #5 of 23 kHeavyHash miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in March 2024.
