The miner consumes only approx. 17–25 watts – depending on how much power you demand from it - all our miners are preset to approx. 19 watts. At average electricity prices in Germany, it costs 0.15 - 0.20€ per day. Your refrigerator consumes significantly more. And doesn't make any money.

Yes. Especially with our premium Noctua fans from the Ice and Polar Line, it is extremely quiet (25–35 dB). Many customers use it directly in the bedroom or living room without hearing it.

The complete setup takes less than 5 minutes. You plug it in, connect to the miner's Wi-Fi, and enter your Bitcoin address. After that, it runs fully automatically. If you don't have a Bitcoin address yet, that can also be done in 5 minutes. Feel free to contact us if you have any questions.

Realistically, a solo block is found every few days, and the miner who succeeds receives the full €300,000. Until then, your miner tries 24/7. Your advantage: You pay once for the miner and can play along for years. In contrast, if you participate in a pool, you would only earn a few cents per day - that wouldn't even cover the electricity costs.

Every Polarblocks Miner comes with a 12-month warranty and a 30-day money-back guarantee. We are a German company and personally handle support. In case of a defect, we will repair or replace the device quickly and easily, as long as we do not detect any hardware or software changes to the device.

Yes, completely legal. You simply have to pay tax on the Bitcoin you earned as income (just like with stocks or other cryptocurrencies).

No. You only need a Bitcoin wallet address (e.g. from an app like BlueWallet or Relai). Everything else happens automatically.

With our high-quality cooling and premium components, a lifespan of 5–8 years is realistic. The fans can be easily replaced if needed.

The next halving is expected in 2028. Until then, the block reward will remain at 3.125 BTC (approx. €300,000). Many customers see now as the best time to enter the market.

Yes. Bitaxe devices are in high demand and retain their value well. You can resell them without significant depreciation. High-quality devices, such as those from Polarblocks, are particularly sought after.
