Payment with cryptocurrency:

Payments are processed by Coinbase Commerce, a reputable payment gateway. We accept Bitcoin, Bitcoin Cash, DAI, Litecoin, Ethereum, and USDC as payment. Please keep in mind that Coinbase Commerce only accepts payments via the ERC-20 network for USDC, DAI, and Ethereum. Sending and receiving unsupported assets via Wallet may result in their loss.

The cryptocurrency amount corresponding to the total balance of your placed order will be provided during checkout using the current exchange rate of that cryptocurrency to GBP.

Because all Coinbase Wallet transactions are performed on the blockchain, senders will be charged a miner fee.

Please be aware that some asset issuers may send or “airdrop” cryptocurrencies to your Wallet even if you are unable to withdraw them. This is known as a “Frozen Drop.” Please contact the asset’s issuer directly for instructions on how to relocate these assets. Assets cannot be transferred unless they are returned to the sponsored exchange.

Please keep in mind that an asset can begin as an ERC-20 and then migrate to its own blockchain, which may or may not be supported.

Shipping Procedures

Your order will be processed and shipped within two to three business days. Orders shipping to international destinations are subject to additional shipping charges.

Upgraded shipping services are available for a fee.

We will send you a shipment confirmation email with tracking information for your products once your order has shipped. The shipping carrier typically requires one business day from the time you receive this notification to validate the tracking information.

Your order may arrive in multiple shipments or be sent directly from our shipping facilities in the United Kingdom, China, Hong Kong, Taiwan, and the United States, depending on your shipping address and product availability. Any shipping or delivery dates provided are only estimates; we are not responsible for any delays caused by the manufacturer or machine production.

Please inspect all packages when you receive your shipment for items such as power supplies, manuals, cables, or any applicable accessories for the product(s) ordered. Please keep the box, the outer shipping carton (if applicable), and all packing materials in case you need them for a return shipment. Any damage that occurs during shipment must be handled directly by the customer with the carrier. When a claim is received, the carrier may request that the item be inspected.

Coin Mining Machines includes VAT on all UK orders sold and delivered in the UK. All international orders sold and delivered by Coin Mining Machines are VAT exempt. We are not responsible for any duties, taxes, or fees that the customer may incur. It is the responsibility of the customer to be aware of local duties and tax laws, as well as to deal with any customs issues that may arise. Coin Mining Machines will not be liable for any cost, damage, or expense incurred as a result of an error in calculating taxes and duties on your order.

Undeliverable packages

Packages are occasionally returned to us undeliverable. If this occurs, every effort will be made to contact you and make arrangements for re-shipment. If you refuse delivery, you will be responsible for the cost of resending the parcel as well as storage fees.

Please keep in mind that upon delivery of the products to the carrier, our delivery is considered complete, and the title and risks of damage and loss of the products are transferred to you. This includes potential shipping costs as well as Chinese import taxes. We do not accept refund requests in the event of a customs clearance failure.

Antminer Upkeep Disclaimer

Coin Mining Machines accepts no liability or responsibility for any decision made by any of our product manufacturers to scrap or refuse repairs on a miner or its components. You, the client, acknowledge that you fully understand the risks associated with this repair process and that Coin Mining Machines is fully indemnified and cannot be held liable for any loss or damage incurred during the shipping or repair process.

The turnaround time is determined by the manufacturer of each miner, not by Coin Mining Machines. We will keep you updated on the progress of the process.

The following are the costs associated with this transaction:

  • Courier charges from the manufacturer to you, the buyer.
  • Before sending the miner, a Coin Mining Machines Technician will provide a technical report and analysis.
  • I-Pay and/or Virtual Card Services charge transaction fees.
  • Repair and Return Directive for SARS
  • Repair Follow-ups and the Ticket Process
  • The total cost of administration for the entire process.
  • Testing of the returned machine, accompanied by a Technical Report

NB: Miner is returned to the customer. If a miner has been repaired and returned to Coin Mining Machines or yourself by any manufacturer and it was damaged during transit, we cannot be held liable and will attempt to pursue a remedy with the manufacturer, but the client may be required to pay associated costs of returning the miner for the second time. This is a risk, and you should be aware of it before proceeding with this transaction.

If all repairs are not paid for, the items will be discarded. If Coin Mining Machines pays for the repairs on your behalf and you do not pay for them, Coin Mining Machines reserves the right to sell the entire unit to recoup costs, and Coin Mining Machines will not be held liable for any damage or loss.

Customers should use a courier service that provides the following services for all returns:

  • Shipment tracking ensures the safe return of your package and declares the full value of the shipment, failing which loss or damage is your responsibility.

If you send us creative ideas, suggestions, proposals, plans, or other materials (collectively, “comments”), whether online, by email, by postal mail, or otherwise (collectively, “comments”), you agree that we may, at any time, without restriction, edit, copy, publish, distribute, translate, and otherwise use any comments that you forward to us in any medium.

Getting in Touch

If you have any questions about the Terms of Service, please contact us at:



Do’s and Don’ts:

  1. Examine the miner for cosmetic damage or loosened heat sinks. Please contact us right away if you notice any damage or defects, or if you find any loose heat sinks.
  2. Place the miner in a dust-free environment with free-flowing air.
  3. Discharge static electricity or wear anti-static PPE while installing or maintaining the miner.
  4. When installing or maintaining the miner, unplug it. The control board will be damaged if this is not done.
  5. Use a power source with a power output that is 20% greater than the miner’s power requirement. The hash rate will be low if the actual output of the power source does not meet the power requirements of miners.
  6. Correctly connect the positive and negative D/C power 6-pin connectors of the PSU to the miner’s control board and hash boards.
  7. Use a single power supply for each miner. The miner can receive power from multiple PSUs, but each hash board can only receive power from one.

Because the 6-pin power connectors are interchangeable, the order in which they are connected to the miner is irrelevant.

  1. Turn on the hash boards first, then the control board. If you’re only powering one miner with a single PSU, you can turn it on right away after connecting the hash boards and control board.
  2. Check that the miner is properly grounded/earthed.
  3. Install lightning protection; otherwise, if struck by lightning, all equipment may be damaged.
  4. Antminers only support Ethernet connections and do not support WiFi connections.
  5. In the event of an internet connection or network failure, the miners do not need to be unplugged and rebooted if it can be resumed within 15 minutes.

If the failure cannot be repaired in a reasonable amount of time, turn off the miner. The miner will crash if the internet connection is unstable.

Different routers have different configurations; check with your router provider to find out how many miners can be connected to your router.
A 1 Mbps internet connection can support up to 150 miners.

  1. A miner consumes approximately 500 MB of internet bandwidth per month; plan accordingly if you are using a data card.
  2. Use the browsers that are supported: Google Chrome and Firefox.
  3. Clean and dust the miner on a regular basis. The miner will be harmed if the air in front of the heat sinks is blocked.

7 Don’ts to Avoid:

IMPORTANT: Do not use multiple power supplies to power a single hash board.

  1. Do not use the miner in a confined or enclosed space. Any items that obstruct the miner’s air flow are prohibited.
  2. Do not use the miner in an environment with a high level of condensation, salt content, or humidity in the air.

The recommended humidity level is less than 65 percent. Coastal areas have high salinity in the air, which can easily damage the hash board.

  1. Do not operate the miner in high temperatures. It is recommended that the working temperature range between 5 and 35 degrees Celsius.

The hash rate will be low when the ambient temperature is low. The miner will fail if exposed to high temperatures for an extended period of time.

  1. Do not use a water curtain (for cooling) in a situation where there is a lot of dust because the water vapor will stick to the dust and corrode the hash boards.
  2. The use of PoE function switches or routers is prohibited because the control board will be damaged.
  3. Do not touch the control board and fan connectors, as they are directly connected to the IC pins. In the absence of electrostatic discharge, touching these connectors will damage the IC, causing the miner to malfunction.
  4. Avoid using a miner that appears to be damaged.
