Is the Ofen 3 Pro profitable?
Not at $0.08 per kWh. The 21energy Ofen 3 Pro mines Bitcoin on the SHA-256 algorithm at 60 TH/s, drawing 1,100 W (18.3 J/TH). At $0.08 per kWh it earns about $1.79 a day but spends $2.11 on power, so it loses $0.32 a day.
It’s #105 of 269 SHA-256 miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in September 2026.
