21 Strategy isn't an anonymous corporation. We're Michel and Heiko — two bitcoin entrepreneurs with a clear mission: make mining transparent, personal, and profitable.
When we started mining bitcoin we ran into the same things many do: opaque providers, hidden costs, no real support. Cloud mining platforms where you never know if the hardware actually exists. English-only contracts, corporate seats in the Seychelles.
We wanted to do it differently. So we founded 21 Strategy — with European contract law, personal support, and the benefits of cheap international data centers.
The result: a bridge between the efficiency of global mining infrastructure and the reliability of a European company. You don't just have a hosting provider, you have a partner who speaks your language — literally.
“Our clients have our personal mobile number. No ticket system, no chatbot — us.”
No anonymous profile pictures. Real contact people with real phone numbers.
Builds the bridge to the Spanish-speaking market from Gran Canaria and runs international relationships. Responsible for expanding international partnerships.
Your point of contact for the Spanish market and international hosting questions.
Runs day-to-day operations of 21 Strategy GmbH from Berlin. Responsible for client support, strategy, and operations. Over a decade of experience in financial markets.
Your first point of contact for everything around hardware selection, hosting options, and mining strategy.
Not just words — this is how we work every day.
No hidden costs, no fine print. You always know exactly what you pay and why. Our contracts are clear and understandable — in English or German.
We think long-term. One-off sales don't interest us — we want your mining to be profitable. Your success is our business model.
You buy the hardware, choose the pool, control the wallet. We're infrastructure providers — not owners of your assets.
No chatbot, no ticket queues. You reach us directly by phone, WhatsApp, or email. Personal, fast, binding.
We use the world's best locations for cheap power — but the contractual relationship stays European. German GmbH, German law, English-speaking support.
We pick locations with renewable energy: hydropower in Asia, wind and solar in the US. Profitable mining and responsibility aren't mutually exclusive.
Our clients aren't customer numbers. They're the people we work with.
Who use mining as tax optimization and a cashflow channel. Depreciate hardware, generate bitcoin revenue — with a professional setup instead of basement improvisation.
Who don't just want to buy bitcoin but produce it. Privacy advantage, DCA on autopilot, and an additional asset (hardware) with resale value.
Who want to integrate bitcoin mining as a strategic investment. From single ASICs to multi-megawatt deployments — with European contract structure and personal support.
Minenity is a brand of 21 Strategy GmbH, registered in the Berlin Commercial Register. Our office is in Berlin-Spandau, and our partner data centers are in the US and Asia.
All contracts are signed under German law. You always have a European contract partner — tangible and locatable, no shell companies, no offshore structures.
No queues, no form that ends up in limbo. Call us directly or write us — we take time for your questions.
