Do you ship miners worldwide, and how long does delivery take?

Yes, we ship to virtually every country via express courier. Delivery typically takes 3–7 business days after dispatch, and every order includes tracking. Because we ship DDP (Delivered Duty Paid), the price you see already covers customs clearance and import fees in most destinations.

What payment methods do you accept?

You can pay by credit or debit card (Visa, Mastercard), SEPA or international bank transfer, and major cryptocurrencies including BTC, ETH and USDT. All card payments are processed through a PCI-compliant payment gateway.

What is covered by the 180-day warranty?

Every miner we sell is covered by a 180-day warranty against manufacturing defects, covering hash boards, control boards and power supplies under normal operating conditions. If a covered fault appears, we repair or replace the unit. Damage from overclocking, physical abuse, liquid ingress or running outside the rated power/temperature range is not covered.

Are import duties and taxes included in the price?

Yes. We ship DDP (Delivered Duty Paid), which means customs duties, import VAT and clearance fees are handled and paid by us before your miner arrives. You will not receive an unexpected bill from the courier in the vast majority of destinations.

Do you test miners before shipping them?

Yes. Every unit is powered on, flashed with current stable firmware and run at full load before dispatch. We verify the reported hashrate, fan operation and board temperatures, and we only ship units that meet the manufacturer's specifications.

Can I mine at home with these machines?

Large ASICs like the Antminer L7 are loud (around 75 dB) and need a dedicated 220V circuit, so they suit garages or outbuildings. For quiet home mining, compact models such as the Goldshell KD Box 2 or the IceRiver KS0 Pro run at under 40 dB on a normal outlet. Profitability at home depends heavily on your electricity rate — as a rule of thumb, rates around $0.10/kWh or lower give small miners a realistic chance of covering costs.
