Our story

Born from frustration. Built for trust.

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.”

— Michel, Managing Director

What drives us

Our principles

Not just words — this is how we work every day.

Radical transparency

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.

Partnership, not transaction

We think long-term. One-off sales don't interest us — we want your mining to be profitable. Your success is our business model.

Your property, your control

You buy the hardware, choose the pool, control the wallet. We're infrastructure providers — not owners of your assets.

Real people, real answers

No chatbot, no ticket queues. You reach us directly by phone, WhatsApp, or email. Personal, fast, binding.

Think global, contract European

We use the world's best locations for cheap power — but the contractual relationship stays European. German GmbH, German law, English-speaking support.

Energy efficiency as a duty

We pick locations with renewable energy: hydropower in Asia, wind and solar in the US. Profitable mining and responsibility aren't mutually exclusive.

Who we work for

Who we work for

Our clients aren't customer numbers. They're the people we work with.

Entrepreneurs and self-employed

Who use mining as tax optimization and a cashflow channel. Depreciate hardware, generate bitcoin revenue — with a professional setup instead of basement improvisation.

Bitcoin investors

Who don't just want to buy bitcoin but produce it. Privacy advantage, DCA on autopilot, and an additional asset (hardware) with resale value.

Companies and family offices

Who want to integrate bitcoin mining as a strategic investment. From single ASICs to multi-megawatt deployments — with European contract structure and personal support.
