Is the Whatsminer M30S+ profitable?

The MicroBT Whatsminer M30S+ mines Bitcoin on the SHA-256 algorithm at 100 TH/s, drawing 3,400 W (34.0 J/TH). At $0.08 per kWh it earns about $3.76 a day but spends $6.53 on power, so it loses $2.77 a day. It only makes money if your power costs less than about $0.046 per kWh.

That puts it #413 of 522 on daily profit across every miner we track, and #162 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.
