Due to current events related to the Greenland discussion, our first development in the Polar Line: Highly optimized Bitaxe Gamma "Greenland" for outstanding performance with one or optionally two Noctua fans. 5€ per miner sold will be donated to Transparency International Greenland.
The models from the Polar Line bridge the gap between the entry-level Eco Line models and the high-performance Ice Line models. The massive aluminum cooler "Bitchin Sink" from The Solo Mining Co. ensures optimal ASIC cooling, supplemented by one or optionally two extremely quiet Noctua NF-A4×20 PWM fans (5V, 40 mm × 20 mm, including Y-splitter with option) plus two high-quality full copper heatsinks on the front and back for active V-Reg cooling. Everything Made in Germany
1. Performance Data
- Hashrate: Factory set to 1.3 TH/s
- ASIC Chip: BM1370 (identical to Antminer S21 Pro)
- Power Consumption: approx. 19 Watts
- Integrated Wi-Fi module (ESP32-S3-WROOM-1) for easy wireless integration
- Configure Wi-Fi: First, connect to the miner's access point (QR code on the display or connect directly to the miner's Wi-Fi).
- Open settings in the browser and connect the miner to your home WLAN.
- Enter Bitcoin address under "Pool": Enter your wallet address and your pool.
- After restarting, solo mining starts automatically.
4. High-Quality Hardware Components
- Display: 0.91″ SSD1306 OLED for live monitoring of hashrate, temperature, and status
- Aluminum cooler "Bitchin Sink" from The Solo Mining Co. + ultra-quiet Noctua NF-A4×20 PWM fan (40 mm × 40 mm × 20 mm)
- VRM Cooling: Two full copper heatsinks on the front and back of the PCB plus optionally one Noctua NF-A4×20 PWM (5 V, incl. Y-splitter)
- Power Supply: 30W 6A power supply included for light overclocking
- (For increased overclocking, you will need a stronger and more stable power supply, e.g., Leicke 50W 10A 5V power supply in German quality.)
- Rare green PCB for the "Greenland" look
- Thermal paste Arctic MX-7
- Heavy Load Stand in Arctic Green designed by @TK_2119913
- Printed using sustainable 3D printing, Made in Germany
The achievable hashrate and efficiency are largely dependent on the chip clock speed. Overclocking without adequate cooling can lead to damage. There is no warranty for damage caused by overclocking or future firmware updates beyond the factory settings.

What Our Customers Say
FAQs
How much electricity does the Bitaxe really use?
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.
Is the Bitaxe quiet enough for an apartment?
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.
How long does the setup take?
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.
How much can I realistically earn?
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.
What if something breaks?
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.
Is Bitcoin mining legal in Germany?
Yes, completely legal. You simply have to pay tax on the Bitcoin you earned as income (just like with stocks or other cryptocurrencies).
Do I need to understand crypto to get started?
No. You only need a Bitcoin wallet address (e.g. from an app like BlueWallet or Relai). Everything else happens automatically.
How long does the miner last?
With our high-quality cooling and premium components, a lifespan of 5–8 years is realistic. The fans can be easily replaced if needed.
What happens at the next Bitcoin halving?
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.
Can I resell the Bitaxe later?
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.
