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.

— Start learning Bitcoin Core and self-custody immediately using testnet or signet mode with small amounts; once you understand encrypted wallet files and PSBT signing, graduated to real Bitcoin becomes straightforward and far more secure than hardware wallet reliance.

— If you lack time or technical confidence to master Bitcoin Core's setup and backup procedures, qualified custodians are a better choice than hardware wallets, since both involve trust but custodians are transparent and regulated whereas hardware wallet security is opaque and attack vectors are numerous.

— Never use leverage, trade derivatives, or participate in yield-bearing schemes on custodian platforms; one liquidation at an unfavorable price wipes the stack; instead, earn a steady income, minimize expenses, and accumulate sats without casino-like risk.
