Availability
Is the Antminer KS7 profitable?
The Bitmain Antminer KS7 (45T) mines Kaspa on the kHeavyHash algorithm at 45 TH/s, drawing 3,465 W (77.0 J/TH). At $0.08 per kWh it earns about $10.71 a day, spends $6.65 of that on power, and keeps $4.06. That’s around $122 a month. It stops making money above roughly $0.129 per kWh.
That puts it #66 of 517 on daily profit across every miner we track, and #1 of 23 kHeavyHash miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in January 2026.
