Is the Antminer S21 XP profitable?
Profit depends on your electricity rate, the miner's efficiency (13.5 J/TH), and the network's current difficulty and coin price, which change daily.
At rated power the 270T bin uses about 87.5 kWh per day. That's about $7.00 a day at $0.08/kWh, or $10.50 a day at $0.12/kWh. The calculator below uses live network data to estimate revenue.
