Bitcoin mining used to be for everyone. We're bringing it back.

Remember when you could mine Bitcoin on a regular laptop? Today, the network is dominated by gigantic, noisy data centers overseas. That goes against everything Bitcoin truly stands for.

We are Dominik and the Polarblocks Team, from Bavaria. And we were tired of leaving mining to the big pools.

Polarblock Labs manufactures quiet 15-watt desktop miners in Bavaria for independent participation in the Bitcoin network. Our mission is simple: We want a node or a miner running in every German-speaking home office again. Quiet. Efficient. And with the chance to win the full block reward.

What we do (and what we don't)

We don't sell "get-rich-quick" machines, and we promise no passive income. Solo mining is all or nothing – a statistical participation with chances that never expire. Those looking for quick money will end up with cloud mining scams. We are the opposite of that.

We build honest, high-quality hardware for Solo Mining (also known as Lottery Mining).

1. No pools, no fees: Your miner works only for you.
2. Plug & Play: You don't have to be a programmer. We flash, test, and configure each miner before it leaves our workshop.
3. The "Big Win" – honestly calculated: Your miner consumes as much power as a light bulb (approx. 15–21 watts). If it hits a block, the block reward of 3.125 BTC + fees is 100% yours – currently around €167,800 (depending on the exchange rate, as of July 3, 2026). The chance for this is about 1 in 15,200 per year. The expected value is below the electricity costs. We state this openly. Don't believe us. Check everything: mempool.space.

Made in Germany: Hardware you can trust

When connecting devices to the power grid that run 24/7, there's no room for cheap compromises. We don't just import finished plastic boxes and stick our logo on them.

Every Bitaxe and every edition is manually assembled by us here in Germany.

Premium 3D printing: We manufacture the housings, stands, and all parts on our own industrial 3D printers. This ensures a perfect fit and optimal airflow.

Cooling upgrades: We know that a miner on the desk must be quiet. That's why we modify the devices with premium fans and optimized heat sinks.

Stress test: No device leaves us before it has proven in our own test setup that the hashrate runs stably.

This is our understanding of hardware quality. And that's exactly why we offer a 30-day money-back guarantee on all our Starter Bundles and miners.

Inflation protection through real hardware ownership – no interest promises

In a time when fiat money is losing purchasing power, many are looking for real preservation of value. A Polarblocks Solo Miner is a piece of handcrafted hardware that you physically own – independent of banks, cloud providers, and middlemen. We don't promise you returns or secure income: the value lies in real ownership and independent participation in the world's most decentralized network.

With the power consumption of a simple LED light bulb, you operate your own decentralized lottery machine. You don't have to be an IT expert. Your miner runs quietly on your desk, protects the Bitcoin network, and participates in the drawing with every new block – with chances that never expire. No banks, no middlemen, no frozen accounts.

Join the Solo Mining Rebellion

It's not just about the potential block reward (3.125 BTC + fees, currently around €167,800, depending on the exchange rate – chance ~1 in 15,200 per year). Every miner running at our customers' homes decentralizes the Bitcoin network a little further and takes power away from the big pools. It's statistical participation with chances that never expire – and a contribution to Bitcoin's security.
