- Prefer not to pay everything at once? A 50% deposit is enough; the price is then 2% higher: deposit 34 526 Kč incl. VAT, and you pay the rest once the miner is on its way.
- The date reflects the factory production date plus a few days for shipping and customs.
- We set up the miner free of charge to mine into your wallet.
How the pre-order works
- You order online and receive an invoice – for the full amount or for a 50% deposit (price +2%).
- Once we receive payment, we order from the manufacturer.
- As soon as the miner has a tracking number, we let you know. With a deposit, you pay the rest at that point.
- You collect the miner in Prague, we ship it to you, or we connect it straight away on our hosting.
