NerdOCTaxe Hydro
- Prefer not to pay everything at once? A 50% deposit is enough; the price is then 2% higher: deposit 5 201 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.

Description
The NerdOCTaxe Hydro is a small open-source miner for the SHA-256 algorithm (Bitcoin). At 11 or 13.8 TH/s it draws around 200–230 W and fits on a desk. With its water block it needs a small water loop with a radiator (if it is not included in the box, check with us before ordering).
What it is good for
- Solo mining (“the lottery”): the miner connects to a solo pool and tries to find a whole block. At this hashrate the chance is very small – treat it as a game, not as income.
- Pool: in a regular pool it mines only token amounts.
- Learning and tuning: web interface, frequency and voltage settings, hashrate and temperature monitoring.
