Frequently Asked Questions
Everything buyers usually ask us, organized by topic.
General
Are these miners tested before they ship?
Yes. Every unit is powered on and run under load in our warehouse. We record the actual hashrate, power draw, and check hashboards and fans before it's listed for sale.
What condition are your miners in?
All hardware we sell is used and bench-tested. Most units are graded like new with no visible wear. Any cosmetic wear or reduced performance is disclosed directly on the listing.
Which states are these miners best suited for?
It depends on your power rate. States like Texas, Wyoming, and Iowa tend to have industrial power cheap enough for high-hashrate air and hydro-cooled hardware. Older or less efficient units are a better fit for home setups or heat-reuse in lower-power-cost areas.
Shipping
Do you ship internationally?
Yes, we ship worldwide from our Portland, Oregon warehouse via DHL Express, with typical transit of 7 to 9 business days. Shipping is free, and the buyer is responsible for any customs duties or import taxes.
How long does domestic shipping take?
Domestic US orders ship via FedEx Ground, which typically takes 2 to 3 business days in transit. Added to our 1 to 2 day processing time, most orders arrive within 3 to 5 business days of purchase, free of charge.
How fast do you process orders?
Every order is processed and shipped within 1 to 2 business days, after each unit passes bench-testing and grading.
Returns & Warranty
What is your return policy?
You have 90 days from delivery to return your order, whether the unit is defective or you've simply changed your mind. Defective returns have no restocking fee. Non-defective returns are subject to a 15% restocking fee.
What warranty do you offer?
Every miner carries a separate 6-month hardware warranty covering hashboard, fan, and control board defects under normal operating conditions, in addition to the 90-day return window.
Do you accept exchanges?
Yes. If you'd like a different model instead of a refund, contact us and we'll arrange the exchange, with any price difference charged or refunded accordingly.
Are returned units re-tested?
Yes. Every returned unit is re-bench-tested before a refund or exchange is finalized, to confirm its condition matches what was reported.
Payment
How do you accept payment?
We accept major credit cards, wire transfer, and cryptocurrency (BTC, ETH, USDT, USDC, and LTC) through a secure, encrypted checkout. Orders paid in crypto receive a 22% discount off the listed price.
Is my payment information secure?
Yes. All payments are processed through an encrypted, PCI-compliant checkout. We do not store full credit card numbers on our own servers.
Will I need to verify my identity?
For large orders, cryptocurrency payments, or orders flagged by fraud detection, we may request identification before shipping. This protects both you and us from fraudulent transactions.
