Co-Ownership instead of Cloud Mining.
You hold shares in a Swiss AG — with the same rights as the founders.
Co-Ownership
You hold shares in a Swiss AG — registered in the commercial register, with voting rights at the Annual General Meeting. Same share class as the founders. No preference rights, no special classes.
Structural Profitability
We currently produce Bitcoin for ~$54,000 — the market price is …. Made possible by 100% hydropower at $0.057/kWh, roughly 40% cheaper than the global average. Profitable in every market cycle.
Sustainability — ecological & economic
100% hydropower. The waste heat from our miners (70–80°C) dries tropical fruits and creates a second revenue stream that can reduce our energy costs by up to 25%. Ecologically clean. Economically more robust.
White Glove Service
We handle everything — site selection, setup, operations, maintenance, reporting. You receive Bitcoin. That's it. For investments from CHF 100,000: dedicated contact, priority allocation in new facilities, and direct access to Sascha.
Radical Transparency
Monthly reports. Real-time dashboard. Quarterly Annual General Meetings with voting rights. Open books. You always know where your capital is and what it's doing.
What you actually own.
No token. No promises.
Land. Energy contracts. Data center. Hardware.
GM3 — Paraguay
Bitcoin Mango — Go-live 2026
The waste heat from our miners (70–80°C) is fed into a drying facility currently under construction. Goal: reduce energy costs by 25% — from $0.057 to ~$0.043/kWh — and build a second revenue stream independent of the Bitcoin price.
What investors earned in 2025.
First full operating year. Without fruit drying. At 50% capacity.
With full expansion
With active fruit drying and 100% capacity: target ROI 10–20% for investors, depending on entry timing.
* Past performance is not an indicator of future results. Investments in digital assets involve risks.
Swiss precision. Bitcoin returns.
Not regulated like an app. Structured like a bank.
Swiss Holding + Subsidiaries
GM Data Centers AG is the Swiss holding company (CHE-200.150.787, Zug). Each facility has its own subsidiary — GM3 Technologies AG, GM4 Technologies AG. Same legal structure as ABB, Nestlé, Glencore.
FINMA + BaFin
FINMA-compliant for Swiss investors. BaFin WIB for the German market. Legally secure in both core markets.
Same share class — no preference rights
GM Data Centers AG (holding) holds the same share class in each subsidiary as external investors. No preference rights, no special rights for the holding company. What you hold, the company holds too — without extra margins or preferential distributions.
Conservative capital management
No overleveraging. We use asset-backed loans exclusively for scaling — never to finance ongoing operations. No margin call risk.
First tokenized company on Bitcoin
Our shares are tokenized and registered on Bitcoin. This makes your position tradable long-term — on a secondary market opening in 2026.
Voting rights at the Annual General Meeting
Every investor votes — on expansion, dividend policy, key decisions. This is not a promise. It's written in the articles of association.
We lost money ourselves. Then we did it better!
Sascha has been investing in Bitcoin since 2012. Over the years he invested in various mining projects and learned what goes wrong: lack of structure, no alignment between provider and investor, zero transparency.
In 2022 he founded Green Mining with a clear thesis: a mining company where investors are true co-owners — with the same rights and the same share class as the founders.
Valentine brings 15 years of experience in communications and consulting. She lost capital herself in the Celsius collapse — and therefore knows the questions investors ask from personal experience.
She has personally spoken with over 250 of our investors. The result: NPS +50. 83% rate the experience as "excellent".
94% of our investors rate us as excellent.

Frequently asked questions.
The exact opposite. With cloud mining you own nothing — no contracts with real rights, no ownership. With Green Mining you buy shares in a Swiss AG, registered in the commercial register. With voting rights. With quarterly reports. With the same rights as the founders.
We currently produce Bitcoin at ~$54,000 (as of March 2026). When the price falls, miners with higher energy costs shut down first. That reduces global hashrate, difficulty drops — and so does our production cost. With a low-cost energy contract and fruit drying as a second revenue stream, we're among the last to shut down. No leverage. No margin-call risk.
Explorer membership is free — you get access to live data, monthly updates, and the community without investing anything. To become a co-owner, the minimum is CHF 1,000 in Germany and CHF 5,000 in Switzerland. For tickets from CHF 100,000, you speak directly with Sascha.
Every quarter we close the books. Based on the company's profit, distributions go directly to your own wallet. The financials are shared transparently. No intermediary. No platform holding your keys.
Co-mining means you become a shareholder in the mining facility instead of running your own solo setup. Resources and expertise are pooled to increase efficiency — earnings are distributed proportionally to all shareholders, without you having to deal with hardware, maintenance, or market fluctuations.
