Is the WhatsMiner M66S++ profitable?

The MicroBT WhatsMiner M66S++ mines Bitcoin on the SHA-256 algorithm at 356 TH/s, drawing 5,518 W (15.5 J/TH). At $0.08 per kWh it earns about $13.37 a day, spends $10.59 of that on power, and keeps $2.78. That’s around $83 a month. It stops making money above roughly $0.101 per kWh.

That puts it #77 of 522 on daily profit across every miner we track, and #56 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 December 2024.
