Terms and Conditions

Last updated 27 October 2026

1. Scope of Application

These Terms and Conditions govern all contracts between Nanohash OÜ, trading as Nerdminer Store (the Seller), and its customers (the Customer) regarding the sale of mining hardware and accessories. The version you agree to at checkout is the version that applies to your order.

2. Products and Orders

The Seller offers Bitcoin mining hardware, including but not limited to Bitaxe, NerdAxe, NerdQAxe and NerdMiner devices, which are primarily intended for solo and home mining.

  • Your order is an offer. The contract comes into existence when we confirm the order by email.
  • Some products are pre-orders and ship at a later date. The expected shipping date is shown on the product page.

3. Prices and Payment

All prices are in Euro and include VAT. Shipping costs are shown before you order and on our shipping page.

  • Payment methods. Card (Visa, Mastercard, processed by PayPal, no PayPal account needed), PayPal, Bitcoin and Lightning through our BTCPay Server, stablecoins (USDC, USDT) and bank transfer.
  • Fees and discounts. For payment via PayPal, including by card in PayPal's card form, we charge a fee of 3% of the order value that reflects PayPal's fee; it is shown at checkout before you place the order. Bitcoin and Lightning get a 5% discount on the goods. No fee applies to Bitcoin, stablecoins or bank transfer.
  • Stablecoins. The amount in US dollars equals the order value at the euro reference rate of the European Central Bank and is shown before you pay. The payment goes straight to our own wallet address, no payment provider is involved. You bear the network fee of the transfer. Please send exactly the amount shown and only over the networks offered.
  • Taxes and duties. Inside the EU, VAT is included in the price and there are no further charges. Outside the EU, your customs authority may charge import duty and local VAT, which you pay.

4. Shipping and Delivery

  • We ship from Europe with UPS, fully tracked.
  • Delivery times shown on the site are estimates for the carrier, counted from dispatch.
  • Risk passes to you when the parcel is handed to you. If a parcel is lost or damaged in transit, tell us and we sort it out with the carrier.
  • If we cannot deliver within 30 days, you can set a short additional period and then cancel the order and get your money back.

5. Right of Withdrawal and Refunds

You may withdraw from your purchase within 14 days of receiving the goods, without giving a reason. How it works, what we refund and when, is set out in full on our withdrawal page and in our returns policy. Nothing in these terms limits those rights.

6. Liability

  • Every device is tested before it leaves us.
  • Mining is not an investment product. We do not promise any yield, and we are not liable for changes in network difficulty, Bitcoin price or electricity cost.

  • The law of the Republic of Estonia applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
