Is the WhatsMiner M73 profitable?

The MicroBT WhatsMiner M73 mines Bitcoin on the SHA-256 algorithm at 470 TH/s, drawing 7,200 W (15.3 J/TH). At $0.08 per kWh it earns about $17.65 a day, spends $13.82 of that on power, and keeps $3.83. That’s around $115 a month. It stops making money above roughly $0.102 per kWh.

That puts it #61 of 522 on daily profit across every miner we track, and #54 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 December 2025.
