Frequently Asked Questions

Why is Self-Custody so important?

Self-custody gives you full control of your Bitcoin. You hold your own private keys, avoiding the risks of exchanges and custodians losing, freezing, or restricting your funds. It ensures true ownership, long-term security, and financial independence.

What does a typical engagement look like?

First, you complete our evaluation form so we can understand your situation. We follow up by email to arrange an online meeting where we review your needs in more detail. After that, we prepare and send you a clear, personalized report explaining the best self-custody setup for you and the estimated costs.

How does SelfCustody21 ensure my privacy without requiring KYC?

We operate fully non-KYC. We never ask for identification, financial documents, or exchange history. Only minimal technical information is collected to understand your needs, and nothing is shared with third parties. Your identity and Bitcoin holdings remain completely private throughout the entire process.

How do I pay for the service?

All payments are made in Bitcoin. After you approve your customized report, we provide a Bitcoin address or Lightning invoice to complete the payment securely. Using Bitcoin as the only payment method helps protect your privacy — no banks, credit cards, or personal financial information are involved.

Can you review my existing self-custody setup?

Absolutely. We evaluate your current setup by examining your security practices, backup structure, and overall risk exposure. This helps ensure your self-custody approach is both safe and aligned with your long-term objectives.
