Is the WhatsMiner M66S+ profitable?

The MicroBT WhatsMiner M66S+ mines Bitcoin on the SHA-256 algorithm at 318 TH/s, drawing 5,406 W (17.0 J/TH). At $0.08 per kWh it earns about $11.94 a day, spends $10.38 of that on power, and keeps $1.56. That’s around $47 a month. It stops making money above roughly $0.092 per kWh.

That puts it #104 of 522 on daily profit across every miner we track, and #84 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 2024.
