The Case for Bitcoin Multisig Custody
September 26, 2026
On Onramp Media's First Principles, Swan Bitcoin's Brandon Quittem tells host Cam Stromme why he sees collaborative multisig as the honest middle ground for long-term bitcoin custody. He also covers the physical risks facing bitcoin holders and why a bitcoin inheritance plan needs legal title, not just key access.
Brandon Quittem joined Swan as an advisor in 2019, came up through marketing and now runs client experience, so he has watched Bitcoin adoption from the first sales call to the recovery call. He tells Cam how Swan began as a gifting platform until users hacked it into a weekly DCA, why the company hired for content first, and why a steady buy is still the best guardrail against our own psychology. The second half turns to custody. Brandon makes the honest case against collaborative multisig before he makes the case for it, and explains why he sees it as the middle ground most holders will actually use. They cover the physical threat to holders, why withdrawal delays add real friction for criminals, Swan's RBX path out of GBTC, and why an inheritance plan needs legal title as well as access to the keys.

Frequently Asked Questions
What is the middle ground Brandon Quittem describes for bitcoin custody?
On First Principles, Brandon Quittem argues collaborative multisig is the practical middle ground between full self custody and handing bitcoin to a single custodian, since no one party can move funds alone (01:01:58).
Why does Brandon Quittem say withdrawal delays help protect bitcoin holders?
He tells Cam Stromme that withdrawal delays add friction that discourages criminals from targeting bitcoin holders for physical theft, since a fast, single-signature withdrawal is easier to coerce (01:24:17).
What does Brandon Quittem say bitcoin inheritance plans often miss?
He explains that giving heirs access to keys isn't enough for a bitcoin inheritance plan — heirs also need legal title, or they can end up holding bitcoin they have no legal claim to (01:37:25).
