Frequently asked questions

Can I use it at home?
At 75 dB, the Antminer S21 is too loud for a living space. Install it in a garage, a ventilated basement or a technical room. To mine inside the house, choose a quiet machine such as the Avalon Q.

What electrical installation do I need?
A dedicated 220–277 V single-phase line able to supply 20 A continuously. Have your installation checked by an electrician before commissioning.

At what electricity price is it profitable?
It depends on the Bitcoin price and network difficulty. Our profitability calculator gives you the net result at your rate, updated continuously.

How do I set it up?
Connect it via Ethernet, open its interface in your browser and enter your pool. Follow our step-by-step tutorial.

Glossary for this product

The technical terms on this page, explained simply.

Full glossary →
  • SHA-256

    SHA-256 is the hash function behind Bitcoin's proof of work. SHA-256 ASICs compute trillions of these hashes every second.

  • Three-phase and single-phase

    Single-phase (230 V) powers most homes; three-phase spreads power across three phases (400 V) and suits several miners.

  • Mining algorithm

    A mining algorithm is the calculation rule a cryptocurrency imposes on its miners, such as SHA-256 for Bitcoin or Scrypt for Litecoin.

  • Autotune

    Autotune is a firmware feature that sets the frequency and voltage of each chip in a miner on its own to find the best balance.

  • Mining difficulty

    Mining difficulty sets the effort needed to find a block. The network adjusts it to keep block production at a steady pace.

  • Energy efficiency

    A miner's energy efficiency shows the energy used per unit of hashrate, in J/TH or J/GH. The lower the figure, the more efficient the machine.

Default: Bitcoin's all-time high (ATH). Revenue follows the price you enter, at today's network difficulty. Indicative forecast, not a reliable source nor a guarantee: based on current hashrate market and cryptocurrency prices, excluding pool, hosting and maintenance fees. Real income varies with prices and difficulty.

Profitability history of this machine

What it would have earned each day, recalculated with the coin price, difficulty and network rewards of the time.

 

Simulation: this machine (current hashrate and power draw) running every day of the period, at today’s purchase price, with the electricity price of the calculator above. Network hashrate grows over time: past revenue does not predict future revenue.
