OneMiners Café Prague: Where Bitcoin Mining Warms Your Coffee and Your Day

Opening a café is one thing. Building a space where coffee, cryptocurrency, and cozy warmth coexist is another. At OneMiners Café Prague, located at Rostovská 260/2b, 101 00 Praha 10 – Vršovice, we’ve taken that bold step. This is more than a café — it’s a live exploration of what the future of coffee (and mining) can be.

The Core Tech: Bitmain Antminer S21 XP in Action

At the heart of OneMiners lies a deceptively quiet powerhouse: our Bitmain Antminer S21 XP, churning away at 270 TH/s. In a typical setup, that machine would roar at 85 decibels — loud enough to drown out conversations or crackle above a busy street. But ours sits inside a custom anti-noise box, cutting the noise down to just 35 decibels. In practice, it’s more “gentle purr” than “industrial drone.”

Why do this? Because our goal is to integrate mining, not isolate it. We want customers to see, sense, and feel the technology — but without discomfort.

Heating & Efficiency: Mining + Warmth

Here’s where things get really clever: our miner isn’t just working in isolation — it’s heating the café as it mines. One unit is enough to warm up to 70 m² of space, turning the miner into both a revenue source and a thermal engine.

During Prague’s colder months, that heat becomes part of the ambiance: cozy, whisper-quiet, and decidedly futuristic.

We’ve heard from customers in Germany who use two of these miners in their car salons — they report the ambient warmth is like entering a small sauna. In our setting, it’s the perfect counterpoint to sipping a hot latte or matcha.

Earn While You Relax: Real-World Yield

While you enjoy your drink, the miner runs in the background. Its earning potential? Up to $14 a day, or approaching $6,000 a year (depending on electricity, difficulty, etc.). In short: we’ve turned something abstract — mining Bitcoin — into something you can experience during your daily coffee break.

And yes, in true crypto spirit, you can pay for your coffee (and other items) using Bitcoin directly in the café. It’s not just novelty — it’s a lived experiment in making crypto usable.

The Menu & Service: From Matcha Mornings to After-Work Drinks

Let’s talk taste. We didn’t trade out ambiance for tech — we elevated both.

• Coffee & Specialty Drinks: Espresso, pour-over, flat white, cold brews.

• Matcha & Wellness Beverages: Creamy matcha lattes, herbal infusions.

• Alcoholic & Signature Cocktails: Craft beer, wine, small-batch spirits, curated cocktails.

• Everything is freshly prepared, with ingredients selected daily.

• We aim for 10/10 service — attentive, warm, knowledgeable.

Whether you're a regular looking for your morning pick-me-up or a newcomer drawn in by the mining box, we want the experience to feel polished, friendly, and just a little magical.
