Bitcoin education & self-custody · for institutions

If you don't hold the keys,
you don't own the Bitcoin.

Private, hands-on mentoring for corporations, investment funds, and high-net-worth individuals — from monetary theory to institutional-grade cold storage. Delivered in Danish or English, in person or online, under strict confidentiality.

Non-custodial — we never touch your funds

Banks lend out what you deposit. Bitcoin lets you hold your treasury outside the system — beyond freeze, confiscation, or inflation.

Most companies never realise that a deposit isn't money set aside for them — under fractional-reserve banking only a fraction is held in reserve; the rest is loaned out or invested. In a crisis, that means frozen withdrawals, limits, or worse.

21LIBERTY exists to change that. We teach individuals and institutions to secure wealth by holding their own private keys — with the same open-source tools and multisig architecture used by the most security-conscious holders in the world.

Three ways we bring you from curiosity to command.

Structured knowledge, hands-on custody, and strategy for the boardroom — each engagement tailored to your team's technical level.

From one key to institutional multisig.

Real ownership begins with mastering your private keys. We guide you through each stage with precision — hardware to multisig, privacy to inheritance.

"Time and again I explain why self-custody matters. If you don't hold your private keys, you don't truly own your Bitcoin. My workshops give clients hands-on mentoring in self-custody — guiding them, step by step, to take full control with confidence."

21LIBERTY is part of LIBERTAS X GROUP LLC. It operates solely as a Bitcoin educator and mentor — never as a financial advisor, and never handling client funds.
