Is the Antminer S21+ Hyd profitable?
Profit depends on your electricity rate, the miner's efficiency (15 J/TH), and the network's current difficulty and coin price, which change daily.
At rated power the 395T bin uses about 142.2 kWh per day. That's about $11.38 a day at $0.08/kWh, or $17.06 a day at $0.12/kWh. The calculator below uses live network data to estimate revenue.
No guarantees. Mining revenue changes with the market. This is an estimate, not financial advice. Send us your power rate and we'll go through the numbers with you before you buy.
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.
