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 3564W of continuous draw this unit uses about 86 kWh per day and roughly 2566 kWh per month. That is about 257 € per month at 10 ct/kWh, 513 € at 20 ct/kWh and 770 € 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.
