The Bitcoin Standard Podcast
341. Bitcoin Custody with Ben Westgate & BTC Pavao
- Bitcoin Core's superiority for key generation and self-custody, with ~18 years of security review and the largest reviewing base of any Bitcoin software making entropy attacks on it statistically less lucrative than other targets.
- Hardware wallet risks exposed by the Coldcard entropy bug affecting ~1,000 Bitcoin; emphasis on generic hardware and well-reviewed operating systems (Debian, Linux) over Bitcoin-specific devices.
- BIP39 seed phrase flaws including weak key stretching, no error correction, language-dependent word lists, and user temptation to create brain wallets with insufficient entropy; comparison to superior alternatives like Codex 32.
- Self-custody setup using air-gapped laptops: offline signing device plus online node synchronizing the blockchain; Bitcoin Core supports offline signing via partially signed transactions (PSBTs) without command-line knowledge required.
- Backup strategy using encrypted wallet files (not raw seed phrases) stored on multiple media types (CDs, metal, paper) in separate locations, with passphrases kept apart from wallet files to balance redundancy and security.
- Dangers of leverage, derivatives, futures, and lending schemes offered by custodians; these are zero-sum games with liquidation risk and ecosystem harm; gambling with Bitcoin stacks destroys wealth far faster than patient accumulation.
