Self-custody: not your keys, not your coins

The single biggest mental shift in crypto: you can actually own your money. Here's what that requires.

> What it means

Self-custody means holding your own private keys — no exchange, no custodian, no company can freeze, seize, or lose your funds. It also means no password reset, no support line, and no do-overs. Full control comes with full responsibility.

> How to do it right

Use a hardware wallet (Ledger, Trezor) for meaningful amounts. Store the 12/24-word seed phrase offline, in at least two physical locations — metal seed plates beat paper. Never type it into any website, ever. Never take a photo of it. Never store it in a password manager or the cloud.

> A safer middle ground

For small amounts you're actively using, a hot wallet (Rabby, Phantom) is fine. For your long-term stack, a hardware wallet with a separate 'vault' address that never signs risky transactions is the standard institutional-grade setup.
