Is the WhatsMiner M7A profitable?

The MicroBT WhatsMiner M7A mines Bitcoin on the SHA-256 algorithm at 526 TH/s, drawing 10,000 W (19.0 J/TH). At $0.08 per kWh it earns about $19.75 a day, spends $19.20 of that on power, and keeps $0.55. That’s around $17 a month. It stops making money above roughly $0.082 per kWh.

That puts it #136 of 522 on daily profit across every miner we track, and #113 of 262 SHA-256 miners on efficiency. It isn’t in stock with us at the moment. It’s a hydro (water-cooled) unit, released in July 2026.
