Is the Antminer S21j XP Hyd profitable?
Profit depends on your electricity rate, the miner's efficiency (12 J/TH), and the network's current difficulty and coin price, which change daily.
At rated power the 495T bin uses about 142.6 kWh per day. That's about $11.40 a day at $0.08/kWh, or $17.11 a day at $0.12/kWh. The calculator below uses live network data to estimate revenue.

Cooling infrastructure required. This is a hydro-cooled unit. Plan for three-phase power and a coolant loop with a dry cooler, or an ANTSPACE container.
