Frequently Asked Questions

We accept major credit and debit cards, bank transfer and popular cryptocurrencies including Bitcoin (BTC), Ethereum (ETH) and USDT. Card payments are processed through our secure checkout, and crypto orders receive a wallet address and exact amount at checkout. Your order is confirmed as soon as payment clears, and you will receive an order confirmation email. If you need a proforma invoice for a bank transfer, contact our team.

Yes — every order is placed through our encrypted checkout and you always receive a written order confirmation and invoice. Only ever send funds to the bank details or wallet address shown on crypto-miner-shop.com or in an official invoice from our team, and never to details sent through unofficial channels. If anything looks unusual, contact us before paying and we will verify your order.

As soon as your order is dispatched, we email you a tracking number and a link to the courier’s tracking page. You can follow your miner door-to-door, and tracking typically activates within 24 hours of pickup. Full details are in our shipping policy, and our support team can check the status for you at any time.

Contact us as quickly as possible — we can usually change or cancel an order free of charge before it has been dispatched. Once a miner has shipped, changes are no longer possible and the terms of our refund policy apply instead. Reach us via the contact page with your order number.

Yes, we ship ASIC miners, GPU rigs and accessories to most countries worldwide, with free worldwide DDP delivery on qualifying orders. A small number of destinations are restricted for regulatory or logistics reasons — the current list is in our shipping policy. If your country is not shown at checkout, ask us for a quote.

Orders are processed and dispatched within 48 hours of payment confirmation. After dispatch, express courier delivery typically takes 3 to 7 business days depending on your region, with remote areas taking a little longer. You will receive a tracking number the moment your parcel leaves our warehouse.

For most destinations we offer DDP (Delivered Duty Paid) shipping, which means import duties and taxes are covered in your order total and you pay nothing extra on delivery. Where DDP is not available, any local duties are the buyer’s responsibility and are clearly flagged before checkout. See our shipping policy for the details per region.

Yes — miners are shipped in plain, unbranded outer cartons with no reference to cryptocurrency on the label. Inside, units are foam-protected and sealed, and shipments are insured against loss or damage in transit. More detail is in the packaging section of our shipping policy.

We source hardware directly from manufacturers and authorized distributors, and every unit is genuine and verifiable by serial number. Listings are clearly labelled as new, used or manufacturer-refurbished, so you always know exactly what you are buying. Browse the full range in our shop.

Yes — every unit goes through a 24-hour burn-in and hashing test before it is packed, so a dead or underperforming machine does not leave our warehouse. Test results can be shared with your order on request. If a unit still arrives faulty, our DOA process in the refund policy covers you.

It depends on the model: many ASIC miners ship with an integrated or bundled PSU, while some are sold as miner-only. Each product page lists exactly what is in the box, including plug type and voltage. If you need a compatible PSU or C19/C13 cable, check the accessories on the product page or ask us.

In most cases yes — popular models restock regularly and we can reserve a unit from the next batch for you. Lead times for pre-orders are quoted individually and depend on the manufacturer’s production schedule. Contact us with the model you want, or browse in-stock Antminer models available now.

Our miners include a 180-day warranty from the date of delivery. The warranty covers manufacturing defects and hardware failures under normal operating conditions, but not damage from overclocking, incorrect voltage, physical misuse or opened hashboards. Keep your invoice and the unit’s serial number — they are required for any claim.

Report the fault to us within 7 days of delivery with your order number, a short video of the issue and photos of the unit and packaging. Our technicians will first help you troubleshoot remotely, and if the unit is confirmed DOA we arrange a repair, replacement or refund according to our refund policy. Do not open the chassis or remove warranty seals before contacting us.

Unopened, unused items can be returned within 30 days of delivery — full terms are in our refund policy. Opened or used miners are generally not returnable except under warranty or DOA terms. Contact support first so we can issue return instructions and an RMA reference.

For confirmed DOA units and valid warranty claims, we cover the return shipping costs. For change-of-mind returns of unused items, return shipping and any restocking fee are the buyer’s responsibility. Full conditions are listed in our refund policy.

You can, but plan for noise, heat and power: a typical full-size ASIC runs at around 70–75 dB — about as loud as a vacuum cleaner — and needs a dedicated circuit and good ventilation. Many home miners use a garage, basement or sound-insulated enclosure, or choose smaller low-power units instead. Our beginner’s guide to cryptocurrency mining walks through home setups step by step.

It varies widely by model: a modern air-cooled ASIC such as a current-generation Antminer draws roughly 3,000–3,600 W continuously, while smaller or GPU rigs can use far less [illustrative figures — check each product’s specs]. Your monthly cost is simply power draw (kW) × 24 hours × 30 days × your electricity rate. Our guide on choosing the right ASIC miner shows how to compare efficiency (J/TH).

It can be, but there are no guaranteed returns — profitability depends on the Bitcoin price, network difficulty, your miner’s efficiency and, above all, your electricity rate. Run the numbers for a specific model with an up-to-date mining calculator before you buy, and treat any site promising fixed returns like “1 BTC in 30–45 days” with caution. We’d rather you mine with realistic expectations: start with our beginner’s guide.

It depends on your budget, electricity price, available space and noise tolerance — there is no single “best” miner for everyone. Many first-time buyers start with a proven, efficient model from the Antminer range because parts and firmware support are easy to find. Read how to choose the right ASIC miner, then compare live prices in the shop.

Yes — mining rewards are paid to a wallet address you control, so set one up before your first payout. For anything beyond small test amounts we strongly recommend a hardware (cold) wallet so your keys stay offline; see our hardware wallet range and our explainer on what a cold wallet is. Never mine to an address whose seed phrase you do not personally hold.
