Is the Whatsminer M3X profitable?

The MicroBT Whatsminer M3X mines Bitcoin on the SHA-256 algorithm at 12.5 TH/s, drawing 2,050 W (164 J/TH). At $0.08 per kWh it earns about $0.47 a day but spends $3.94 on power, so it loses $3.47 a day. It only makes money if your power costs less than about $0.010 per kWh.

That puts it #451 of 522 on daily profit across every miner we track, and #255 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 March 2018.
