Is the Whatsminer M30S++ profitable?

The MicroBT Whatsminer M30S++ mines Bitcoin on the SHA-256 algorithm at 112 TH/s, drawing 3,472 W (31.0 J/TH). At $0.08 per kWh it earns about $4.21 a day but spends $6.67 on power, so it loses $2.46 a day. It only makes money if your power costs less than about $0.050 per kWh.

That puts it #391 of 522 on daily profit across every miner we track, and #160 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 October 2020.
