Why used Antminers often deliver the better return
A used Antminer costs a fraction of a new one but mines the same blocks. As long as your electricity is cheap enough, payback time — not efficiency — drives the return, and payback is structurally shorter on a 319 € unit than on a 1,379 € one. That is why used hardware is the usual entry point for anyone with solar, heat reuse or a commercial tariff.
The risk is not age but origin. Farm ASICs run continuously under controlled conditions and are usually in better shape than sporadically used private units — provided someone tests them before sale.
Our testing process before shipping
- Visual inspection of chassis, PSU, fans and cabling
- Cleaning of heat sinks and air paths
- Full-load test run with a log of the achieved hashrate
- Verification of all hashboards and chip temperatures
- Working firmware, factory configuration restored
Checklist for buying used
Never buy without a logged hashrate, an invoice showing VAT and a reachable contact. Ask about hashboard condition, whether the PSU is original, and whether the unit ever ran under water or immersion cooling. Photos of the actual unit are standard, not a favour.
Also compare price per terahash: divide price by hashrate. At 319 € and 96–100 TH/s that is roughly 3.2 €/TH — a figure that makes offers across models directly comparable.

Shipping, warehouse and delivery time
Stocked units ship within 2–4 business days from our warehouse in Bavaria, Germany. Because the hardware is already imported and cleared inside the EU, there is no import VAT, no customs paperwork and no waiting for air freight from Asia. Models sourced directly from the factory show their own delivery time on the product page.
We ship insured to Germany, Austria, Switzerland and the rest of the EU. Orders above 1,000 € ship free within Germany, and express shipping is available for stocked units.
Payment, invoice and warranty
You can pay by bank transfer, credit card, PayPal, Apple Pay or cryptocurrency. Every order comes with a proper invoice showing VAT. EU business customers with a valid VAT ID are invoiced at 0 % under the reverse-charge scheme, and we can switch your session to B2B mode with net prices.
Most new miners come with a 6-month warranty. Used units are tested, cleaned and shipped with a logged hashrate; the exact commitment is stated on each product page.
Advice before you buy
We help you check electricity tariff, power connection, cooling, noise and realistic payback before you order — including when the honest answer is that a machine will not pay off at your kWh price. Send us your electricity cost and the planned location and we will run the numbers with you.
