Is the Whatsminer M30S profitable?

The MicroBT Whatsminer M30S mines Bitcoin on the SHA-256 algorithm at 86 TH/s, drawing 3,268 W (38.0 J/TH). At $0.08 per kWh it earns about $3.23 a day but spends $6.27 on power, so it loses $3.04 a day. It only makes money if your power costs less than about $0.041 per kWh.

That puts it #427 of 522 on daily profit across every miner we track, and #171 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 April 2020.
