Antminer S21: price and volume tiers

All prices incl. 19% VAT, shipped EU-wide.

Availability and delivery

Antminer S21: ordered directly ex works – lead time 10–14 days ex works; we handle import and customs, you pay nothing on delivery.

Electricity cost in continuous operation

At 2650W of continuous draw this unit uses about 64 kWh per day and roughly 1908 kWh per month. That is about 191 € per month at 10 ct/kWh, 382 € at 20 ct/kWh and 572 € at 30 ct/kWh. Compare that figure with the daily revenue at current difficulty before ordering — your tariff, not the hashrate, decides profitability.

Setup and operation

Plan a dedicated, properly fused circuit, dust-free intake air and an unobstructed exhaust path. Air-cooled miners run at 70–75 dB and belong in a basement, garage, workshop or server room rather than a living space. Setup takes a few minutes: connect the network cable and enter pool and wallet in the web interface — on request we configure the unit before shipping.
