What if a Bitcoin mining machine could pay for itself while keeping a luxury swimming pool warm through a Swiss winter? That is essentially the experiment behind Villa Volt, the extraordinary five-story St. Moritz residence completed by Swiss investor and Crypto Finance founder Tobias Reichmuth. Set on the coveted Via Tinus above the resort, the property overlooks the town, Lake St. Moritz and the surrounding mountains, while the nearby Chantarella funicular provides convenient access to the slopes and village. Beneath its refined Alpine interiors, however, sits a 5 kW Bitcoin mining system that turns the immense heat produced by cryptocurrency mining into useful warmth for the home and its indoor pool.
Reichmuth bought the plot in 2021, construction began in 2023 and the residence was completed by early 2025, creating a 550-square-meter home spread across five levels and connected by a private elevator, according to Swiss business publication Bilanz. Designed by Ruch & Partner with interiors by Zurich-based Greset Reich, Villa Volt combines Nordic design with Alpine influences, using natural materials, restrained colors, expansive windows and a prominent fireplace to create a calm, contemporary retreat.
The property also has three principal bedrooms and a separate guest apartment, while a heated garage provides space for three large vehicles, each with its own EV charger. The most unusual part of the residence, however, is hidden within its energy infrastructure, where a Bitcoin miner effectively takes the place of a conventional boiler.
A Bitcoin miner becomes a high-tech boiler
In a conventional luxury home, an electric or gas boiler consumes energy primarily to produce heat, with little else to show for that consumption. Villa Volt instead uses a high-powered computer to perform the calculations required for Bitcoin mining, turning the heat generated by those calculations into a useful source of energy. The approximately 5 kW system is comparable to the power draw of a high-end commercial ASIC miner and has been installed by Swiss startup RY3T, which specializes in using Bitcoin-mining hardware as a heat source for buildings.
The system is hydro-cooled rather than relying on conventional fans to expel the enormous amount of heat produced by the mining hardware. Electricity generated by the home’s solar panels powers the miner, while a dedicated cooling liquid absorbs the heat produced by the computer. A heat exchanger then transfers that thermal energy into the home’s hot-water system without allowing the cooling liquid to mix with household water. The recovered heat can subsequently be directed towards the underfloor heating and the swimming pool, meaning the machine simultaneously mines Bitcoin and contributes to keeping the property warm.
That arrangement is particularly compelling in winter, when St. Moritz can be buried under snow and temperatures plunge well below freezing. Rather than treating the heat generated by intensive computing as waste, Villa Volt captures it and puts it to work throughout the property. Reichmuth has said the system generated roughly CHF 300 (around $36) worth of Bitcoin during its first month while also helping heat the pool, giving the installation an additional financial dimension beyond its energy-saving function.
Inside Villa Volt’s private Alpine spa
The centerpiece of the home’s wellness facilities is a 10-meter indoor swimming pool equipped with a counter-current system, allowing Reichmuth to swim against a steady flow without needing a larger pool. Manufactured in stainless steel by Swiss specialist Chromtech AG, it forms part of a substantial private spa that includes a sauna, hammam, cold plunge, gym and meditation room.
There is also a cryotherapy chamber capable of reaching minus 110 degrees Celsius, reinforcing the home’s strong focus on wellness and longevity. With the pool enclosed inside the residence, the experience is less about battling the Alpine winter and more about enjoying a private resort-style retreat while snow falls outside.
Villa Volt reflects Reichmuth’s broader interests in renewable energy, cryptocurrency and longevity. BILANZ estimated his fortune at CHF 125 million roughly $150) in 2025, placing him among Switzerland’s 300 richest people. He founded renewable-energy investment company SUSI Partners in 2009 after an earlier entrepreneurial exit and later co-founded Crypto Finance Group, which provided digital-asset trading, custody and investment services before Deutsche Börse acquired a two-thirds majority stake in 2021.
Through Maximon, he has also backed longevity businesses including supplement company Avea and Zurich clinic AYUN, while Swiss audiences may recognize him from “Die Höhle der Löwen Schweiz.”
The result is a mountain home where luxury and technology are unusually intertwined. Villa Volt pairs panoramic Alpine views and understated interiors with solar power, geothermal energy and Bitcoin mining, while the mining equipment earns cryptocurrency and recycles its otherwise unwanted heat. In one of Switzerland’s most exclusive winter resorts, Reichmuth has effectively turned a cryptocurrency machine into part of the home’s heating infrastructure, making the villa as much an experiment in energy efficiency as it is a private retreat.
