Is the Antminer S21++ profitable?
Profit depends on your electricity rate, the miner's efficiency (16.5 J/TH), and the network's current difficulty and coin price, which change daily.
At rated power the 235T bin uses about 93.1 kWh per day. That's about $7.45 a day at $0.08/kWh, or $11.17 a day at $0.12/kWh. The calculator below uses live network data to estimate revenue.
