Algorithm Information: SHA-256

SHA-256 — what this algorithm is and how it works.

SHA-256 is a cryptographic hash function. Fractal Bitcoin relies on it for proof-of-work consensus. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.

The Bitmain Antminer S21 Pro 245TH/s consumes $6.74 daily, $202.18 monthly, and $2,459.81 yearly in electricity costs.

The Bitmain Antminer S21 Pro 245TH/s uses 3510W of electricity.

The Antminer S21 Pro is manufactured by Bitmain .

The Bitmain Antminer S21 Pro has a hashrate of 245TH/s using the SHA-256 algorithm.

The Bitmain Antminer S21 Pro 245TH/s can mine the following cryptocurrencies:

NiceHash (BTC) Bitcoin

Bitcoin (BTC)

Bitcoin Cash (BCH)

Fractal Bitcoin (FB)

As of August 18, 2026 with an electricity cost of $0.08 the Bitmain Antminer S21 Pro 245TH/s generates $1.80 daily, $54.14 monthly, and $658.75 yearly.

This makes the Bitmain Antminer S21 Pro 245TH/s a profitable choice for mining.

Based on our real-time ASIC mining profit calculation, the Bitmain Antminer S21 Pro is currently most profitable mining Fractal Bitcoin at your electricity rate of $0.080/kWh. This can change as coin prices and network difficulty shift, so check the Mineable Coins table above for the latest ranking.

This ASIC mining profit calculation for the Bitmain Antminer S21 Pro uses live cryptocurrency prices, current network difficulty, and block rewards for every supported coin, combined with your custom electricity rate. Figures update automatically as network conditions change, so the profitability shown reflects current conditions rather than a static estimate.

NiceHash is a hashpower marketplace, not a traditional mining pool — instead of mining a coin directly, you sell your Bitmain Antminer S21 Pro hashrate to buyers and get paid in Bitcoin. Compare the NiceHash row against direct-mining rows in the Mineable Coins table above: whichever shows the higher Profit/Day at your electricity rate is currently the better option for this specific miner.

This miner is not currently listed by any of our verified vendors. You can still use the profitability figures on this page to plan ahead for when new listings appear.
