Yes. We offer a 30-day return policy for change of mind from the date of confirmed delivery. The hardware must be returned in its original, undamaged condition with all original packaging, components, and accessories included. Return shipping costs and transit are the customer's responsibility. Once the returned equipment is received, inspected, and verified at our facility, your refund is processed promptly and issued to the original payment method used for the purchase. Verified defects remain covered under warranty without customer return fees.

Choose a product and review whether it is new or used, its hashrate, power requirements, cooling requirements, included components, stock or batch status, dispatch estimate and warranty. Select the available configuration, add it to the cart, enter accurate billing and shipping details, review the applicable policies and enabled payment method, then submit the order.

Basic setup is usually straightforward for users familiar with networking and electrical safety. Industrial ASIC miners still require correct voltage, ventilation or cooling, noise planning, network access, and safe installation.

Each product page shows its current status. In Stock, Batch Order, Pre-order and Out of Stock do not mean the same thing. Allocation is finalized after cleared payment; use the dispatch estimate shown for the selected product.

Open Serial Support and provide the model, serial number, order number, controller or system version, pool and network details, dashboard screenshots, kernel log, power conditions and a clear description of the issue. Never send wallet recovery phrases, private keys or passwords.

The product page states whether the power supply unit and power cable are included with that miner. Do not assume they are included with every model. Confirm the input voltage, connector, cable and local electrical requirements before checkout.

No. Calculator results are illustrative estimates based on current inputs and current market and network data. Coin price, network difficulty, pool fees, electricity, downtime, taxes, shipping and maintenance can change actual results.

For shipped hardware orders, the commercial invoice or required shipping documentation is provided electronically and, where required, with the shipment. A copy of the invoice will also be sent to your registered email address, and once the order is completed, you will be able to download the invoice as a PDF directly from your account. Where applicable, the device serial number will be added once the specific unit has been allocated or dispatched.

Review the website for current stock, product specifications, new and used condition information, batch availability and supplier updates. You can also subscribe to product updates when available.

Where a power supply or power cable is included, the selected configuration or confirmed destination determines the compatible option when available. Always verify the miner input voltage, connector, cable and local electrical requirements before installation.

Yes. ASIC hardware prices can change with manufacturer pricing, inventory, network economics, currency, and logistics costs. The current product page and confirmed quotation contain the applicable price.

Used ASIC Global accepts the payment methods displayed at checkout, which may include Visa, Mastercard, bank transfer, and supported cryptocurrency payments.

The available payment options may vary depending on your country, card issuer, or local payment availability. In some locations, Visa or Mastercard payments may not be available, in which case you can simply choose another secure payment option such as bank transfer or cryptocurrency.

All available payment methods will be clearly shown at checkout before you complete your order.

Cash payments and cash on delivery are not available.

New hardware follows the applicable manufacturer warranty and claim procedure. Used hardware sold by Used ASIC Global is covered for a verified internal failure not caused by an exclusion. Warranty does not cover mining profitability, normal performance variation or transit damage handled under a separate shipping claim.

Exclusions may include unsupported software, overclocking or voltage changes, unauthorized hardware modification, unsuitable electrical supply, incorrect installation, misuse, inadequate cooling, operation outside published limits, liquid exposure, poor return packaging and damage not caused by an eligible defect.

No. A change in profitability, coin price, network difficulty or normal performance variation is not by itself a product defect. Return and remedy eligibility depends on condition, authorization, the applicable terms and non-excludable consumer law.

Cloud-mining output is recorded daily in My Account after the disclosed operating deductions. Net earnings accumulate and are paid to the registered supported wallet on the monthly payout cycle stated in the contract.

With delivery, the physical miner is shipped to you. With hosted ownership, you purchase and retain ownership of eligible physical hardware while it is operated under a hosting contract. Your contract and account record the applicable device and service.

The activation target is within 1 business day after confirmed payment and completion of required contract details, subject to allocation, installation readiness and the Hosting & Cloud Agreement.

Hosted-mining charges consist of the electricity rate, management fee and pool fee disclosed in the accepted Hosting Agreement. Hardware setup and deployment are included with no separate setup fee. The accepted rates remain fixed for the active term unless the agreement expressly states otherwise.

The fees shown in your accepted Hosting Agreement remain fixed for the active contract term unless the agreement expressly provides otherwise. Any renewal pricing is disclosed before renewal.

My Account provides the full contract record: real-time and historical hashrate data, the mining pool associated with your contract, gross production, applicable fee deductions, including electricity, management, and pool fees, daily net settlement records, registered payout wallet, transaction references, downtime adjustments, and dispute requests.

The service target is 99% as defined by the Hosting & Cloud Agreement. Planned maintenance, customer-caused issues, pool or network events and qualifying external events are handled under that agreement.

You may request shipment, review a buyback offer or renew hosting under a new accepted term. Storage is free for 90 days after expiry; after that, $30 per device applies for each 30-day period following the required notices.

Hosted mining includes customer ownership of eligible physical hardware. Cloud mining provides only the selected algorithm or coin, hashrate and contract duration; it does not give ownership of a miner, serial number or residual hardware value.

The contract runs for the duration selected on the product page and confirmed in the order and Hosting & Cloud Agreement. Available terms may include 30-day and 365-day plans. The selected coin or algorithm, hashrate and duration are confirmed before activation.

The activation target is within 1 business day after confirmed payment and completion of required details. If activation exceeds the policy threshold, the remedies in the Hosting & Cloud Agreement apply.

Gross output is based on the allocated hashrate and applicable mining results. The dashboard then shows electricity and each disclosed fee or adjustment to reach net output. Network difficulty, coin price and pool results can change output.

No. Cloud-mining income is not guaranteed.

Mining returns can change over time depending on factors such as network difficulty, cryptocurrency prices, mining performance, pool results, electricity costs, applicable fees, and overall market conditions.

Any profitability or income figures shown on the website are estimates based on current conditions and should not be considered a guarantee of future earnings.

Hosted Mining: net mining proceeds are calculated and sent daily to the registered external wallet after the disclosed electricity, management and pool fees and applicable network transfer fee. Cloud Mining: output and deductions are recorded daily; net earnings accumulate and are paid on the scheduled monthly cycle stated in the contract.

Before activation, an eligible cancellation receives a full refund under the applicable order rules. After activation, an eligible refund is calculated pro rata as Contract Price divided by Total Contract Days, multiplied by Unused Days, subject to the Hosting & Cloud Agreement and non-excludable law.

Open the settlement-dispute request from the relevant contract or contact support with the contract, period and disputed calculation. Continue using the current wallet and account details while the written review is pending.

Use suitable rated power, Ethernet, ventilation or approved cooling. Locate the device using Find My Miner or a network tool, then configure a supported mining pool and wallet. Follow the manufacturer instructions for the exact model and observe all electrical and environmental limits.

Provide the serial number, model, order number, dashboard screenshot, kernel log, pool status, network details, temperatures, power conditions and a short video if requested. Do not send wallet private keys or passwords.

Checkout availability depends on the order type. An account is recommended for order history, device records, support cases and wholesale quotes. Always use accurate contact information that you can access.

Identity or business verification is not routinely required. Limited verification may be requested where reasonably necessary for a refund to a different bank account, suspected fraud, account protection, payout validation, or compliance with a specific legal obligation.

Order information may be shared only with authorized company personnel and service providers that need it to process payment, prevent fraud, fulfil delivery, provide hosting or technical support, and comply with applicable law. See our Privacy Policy for details.
