Is the Antminer S19j Pro profitable?

The Bitmain Antminer S19j Pro (104Th) mines Bitcoin on the SHA-256 algorithm at 104 TH/s, drawing 3,068 W (29.5 J/TH). At $0.08 per kWh it earns about $3.91 a day but spends $5.89 on power, so it loses $1.98 a day. It only makes money if your power costs less than about $0.053 per kWh.

That puts it #343 of 522 on daily profit across every miner we track, and #155 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 July 2021.
