Tested by us

Tuned by us

We tune each miner for the site where it runs: more output when energy is cheap, less consumption when it is expensive. We took the S19k Pro to 180 TH/s in immersion, and the S17 Pro takes almost +50%.

Simulate the S19k Pro at 178 TH/s
  • Profiles to suit your energy
  • More output per miner
  • Less consumption in expensive hours
  • Tested on the miners in our shop

Before you plug in

What you need to get a miner working. The simulator does the maths for you.

Electricity

One circuit and one breaker per miner, an RCD in the panel and the right contracted power.

Cooling

Air with extraction, or silence with immersion or hydro and a DCX drycooler.

Network

An Ethernet cable to the miner. No Wi-Fi.

Pool and wallet

A pool account and a Bitcoin wallet to get paid. We help you set them up.

Questions about miners

Do prices exclude VAT?

Yes. We show the price excluding VAT, as companies need, with the VAT-inclusive total below. Invoices carry your company or personal tax number.

Do you deliver the miner configured?

Yes, ready to connect to your pool. If you need it, we help you create the pool account and the wallet.

How much does a miner earn?

It depends on the electricity price, the Bitcoin price and the network difficulty. Our simulator does the maths with today's values.

Do you repair hashboards?

For hashboard repairs we work with AsicMinerPlace, our partner in Greece, with an ASIC repair lab. We handle the configuration, firmware, power consumption and preventive maintenance.

Do you deliver outside Portugal?

New miners are delivered in Portugal; used ones can be shipped by arrangement. Wherever you are in Europe, we can monitor your miners remotely with our AI service.
