Common questions

Before you move your Bitcoin.

What is the safest Bitcoin hardware wallet for most people?

There is no single safest wallet for everyone. The right choice depends on your experience, backup plan, preferred security model, and whether you need features such as multisig or air-gapped signing.

When should I move Bitcoin to a hardware wallet?

Consider a hardware wallet when the amount you hold would be painful to lose. It keeps private keys away from a general-purpose phone or computer, but you still need a tested seed backup and a safe recovery process.

How does the Bitcoin safety audit help?

The audit checks your backup, device access, firmware habits, recovery testing, and inheritance plan. It highlights practical weaknesses without asking for your seed phrase or private keys.
