- 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.
- Hashrate 3.4 GH/s · power draw 1800 W
- We verify availability and price with the manufacturer and suppliers, usually within 2 working days.
- Run it at your home, or straight on our hosting – there excl. VAT and without our margin.
