Anyone who wants to start solo mining in a completely relaxed way has come to the right place.
The NMminer TV is a compact ESP32-based standalone miner for Bitcoin and other SHA256d cryptocurrencies like BCH or DGB, functioning as a smart desktop clock display. With a 1.54-inch color display (240x240 pixels), it shows real-time information such as hashrate (up to 1060 KH/s), time, pool status, and Wi-Fi signal strength – ideal for crypto enthusiasts. This energy-efficient gadget (approx. 0.8–1 W) is powered via USB at 5V, supports firmware updates via NMController, and operates autonomously in standalone mining mode.

What Our Customers Say
FAQs
How much power does the Bitaxe really consume?
The miner consumes only approx. 17–25 watts – depending on how much power you demand from it – all our miners are preset at 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 earn 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 operate it directly in their bedroom or living room without even hearing it.
How long does the setup take?
The complete setup takes less than 5 minutes. You plug it in, connect to the Miner 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 will be found every few days, and the miner who finds it will receive the full €300,000. Until then, your miner will try 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 handle support personally. 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 just have to pay taxes on the Bitcoin earned (as with stocks or other cryptocurrencies).
Do I need crypto knowledge 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 necessary.
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.
