Mining Bitcoin (BTC) & Bitcoin Cash (BCH)
The Antminer S21 is built for the SHA-256 algorithm, which underpins both Bitcoin and Bitcoin Cash. Because both coins use the same hashing function, miners can choose to mine BTC, BCH, or switch between them based on profitability, network difficulty, and pool dynamics.
To mine:
-
Position your miner in a well-ventilated area with strong airflow.
-
Connect to stable AC power (220 V or compatible configuration).
-
Attach an Ethernet cable to your mining pool.
-
Configure wallet and pool settings through the miner’s interface.
-
Monitor hashrate, uptime, and temperature through the dashboard.
With its powerful output, the Antminer S21 is suitable for mining both BTC and BCH depending on your strategy and earnings strategy.
Profitability Considerations
Mining profitability depends on a mix of factors:
-
Bitcoin & Bitcoin Cash market price
-
Network difficulty and hash competition
-
Electricity cost per kWh
-
Mining pool fees
-
Uptime and cooling performance
Because the S21 delivers high hash rate and relatively optimized efficiency, miners can make more informed ROI projections — especially when power cost is competitive. Always calculate projected returns using current price and network realities before committing.
