Is the Antminer Z9 Mini profitable?

The Bitmain Antminer Z9 Mini mines Zcash on the Equihash algorithm at 10 KH/s, drawing 300 W (30.0 J/KH). At $0.08 per kWh it earns about $0.76 a day, spends $0.58 of that on power, and keeps $0.18. That’s around $5 a month. It stops making money above roughly $0.105 per kWh.

That puts it #155 of 522 on daily profit across every miner we track, and #9 of 9 Equihash miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in June 2018.
