Profitability Analysis
As a dedicated ASIC, the Bitmain Antminer S21 XP Hyd is permanently optimised for SHA-256 — the algorithm used by Bitcoin and Bitcoin Cash. It cannot be repurposed for other algorithms, so its long-term viability is directly tied to the economics of those specific coins.
At 5,676 watts and an average electricity consumption of 4,087 kWh per month, electricity cost is the single largest variable in profitability. The difference between $0.04/kWh and $0.12/kWh amounts to $326.94 per month in operating margins — which is why electricity rate selection is as important as hardware selection for any serious mining operation.
Profitability at Key Electricity Rates
All figures assume constant Bitcoin price ($64,000.00) and current network difficulty. Actual results will vary as both change over time.

How to Mine Bitcoin with the Bitmain Antminer S21 XP Hyd
-
Acquire and receive the Bitmain Antminer S21 XP Hyd
Purchase the Bitmain Antminer S21 XP Hyd from an authorised reseller or reputable secondary market. Budget approximately $12,000. Verify the unit is complete and inspect for physical damage before powering on. The unit ships ready to mine — no assembly required beyond power and network connections.
-
Connect power and network
Connect the Bitmain Antminer S21 XP Hyd to a dedicated 5676W power supply on a 16 A+ circuit at 220–240 V. Connect an Ethernet cable to your router. Power on the unit and wait 2–3 minutes for it to boot.
-
Configure your Bitcoin mining pool
Access the miner's web interface by entering its IP address in your browser (find it via your router's DHCP lease list). Navigate to Miner Configuration and enter your chosen pool stratum URL, your Bitcoin wallet address as the worker username, and 'x' as the password. Recommended pools: Foundry USA, F2Pool, AntPool.
-
Monitor performance and optimise
After starting, confirm your hashrate matches the expected 473 TH/s in the pool dashboard (allow 10–15 minutes for the pool to register your worker). Use our live Bitcoin calculator to track daily earnings against your electricity cost. Consider enabling auto-tune mode or third-party firmware (BOS+ for Antminer units) to improve efficiency 5–10%.
