Institutional Custody, Multisig & the War on Cash | Mike Belshe SLP773

Mike Belshe, co-founder and CEO of BitGo, walks through how institutional Bitcoin custody actually works in 2026: qualified custody, self-custody co-signing, and why BitGo still centers a 2-of-3 model after pioneering P2SH multisig in 2013.
BitGo now operates as a US-regulated qualified custodian and public company, while still offering the same wallet stack individuals can run in self-custody mode. The conversation covers what “institutional security” means in practice — HSM-backed co-signing, open-source recovery paths, multi-jurisdictional key storage (including how BitGo moved WBTC when US regulation looked hostile), and why on-chain multisig still beats vendor-locked MPC for cold ops.
They also dig into the political and operational risks around large Bitcoin holdings: KYC and PII as honeypots, France tying names to amounts, the war on cash reaching Bitcoin, and whether an EO 6102-style confiscation risk still belongs in the threat model. On the institutional side, Belshe pushes back on multi-custodian setups that add failure modes, explains insurance limits versus the size of the Bitcoin market, and why splitting wallets matters after events like Bybit.
