Bitcoin in Pusan - November Session: Self-Custody Security

## November Monthly Meetup (November 28, 16:00)

Session - Bitcoin Self-Custody Security

Ever heard the saying "not your keys, not your coins"? Holding your own keys means the responsibility for protecting them is entirely yours.

November's topic is Bitcoin self-custody security: seed phrase generation and backup, key storage methods (hardware wallets, air-gapped setups, multisig), passphrase usage, and the threats that actually matter — phishing, supply-chain attacks, physical threats (wrench attacks), plus the privacy pitfalls that are easy to overlook in self-custody. Whether you're setting up your first wallet or already self-custodying, you're welcome to join.
