Is the Antminer DR3 profitable?

The Bitmain Antminer DR3 mines DCR on the Blake256r14 algorithm at 7.8 TH/s, drawing 1,410 W (181 J/TH). At $0.08 per kWh it earns about $0.00 a day but spends $2.71 on power, so it loses $2.71 a day. It only makes money if your power costs less than about $0.000 per kWh.

That puts it #407 of 522 on daily profit across every miner we track, and #6 of 17 Blake256r14 miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in September 2018.
