The Worst Way To Do Multisig (And What You Can Do Instead)

— Multisig custody requires multiple signatures to authorize transactions; a 2-of-3 setup means any two of three keys can approve a transaction, while single-sig requires only one key.

— Collaborative custody (where a custodian holds at least one key) introduces counterparty risk and contradicts Bitcoin's core principle of eliminating trusted third parties.

— Survey data shows only one in three people using collaborative custody have complete recovery data, meaning two-thirds would be unable to recover Bitcoin if their provider disappears.

— Collaborative custody carries hidden costs including KYC requirements, zero financial privacy, ongoing subscription or percentage-based fees, and potential exit fees.

— Private multisig (no custodial third party) requires users to manage multiple key backups, additional hardware, wallet configuration files, and significantly more operational complexity.

— Single-sig with a strong passphrase can provide robust security for most people without the complexity of multisig, requiring only maximum entropy in seed phrase creation and a highly secure passphrase.

— Before adopting collaborative multisig, verify you have complete recovery data and understand exactly how to recover your Bitcoin without the custodian's software or assistance; if you cannot, you do not truly own it.

— If multisig complexity is unnecessary for your situation, prioritize a single-sig setup with maximum entropy seed phrase generation combined with a strong passphrase rather than adding custodial or operational overhead.

— For shared or multi-party Bitcoin custody scenarios (business treasuries, family stacks, nonprofits, inheritance), multisig remains justified, but only as private multisig without a custodial intermediary holding keys.
