SELF CUSTODY, SECURITY, & THE QUANTUM THREAT TO BITCOIN w/ Alex Leishman

— Self-custody solves third-party risk but imposes 100% operational responsibility on individuals, with most people unprepared for the technical and security burden.

— Inheritance planning remains the most overlooked aspect of Bitcoin security, driving many self-custody holders back toward custodial solutions when they marry or have children.

— Physical security threats—kidnapping, torture, and theft—are real risks for self-custodians; custodians offer protection but introduce counterparty risk.

— River's Force Field feature implements a five-day withdrawal lockdown and weekly spend limits to defend against hacks, SIM swaps, and physical coercion.

— Bitcoin protocol development should prioritize scalability solutions and quantum resistance while maintaining sanctity of the core protocol.

— Better UX design (like BitKey) can lower barriers to self-custody but cannot eliminate human error or operational complexity entirely.

— Before committing to self-custody, test with small amounts ($50–$100) to learn your limitations; only pursue self-custody if you are genuinely confident and prepared for the operational rigor.

— For custodians, prioritize regulated, full-reserve exchanges in the US with monthly proof-of-reserves verification (Coinbase, Kraken, River, Cash App) over yield-bearing platforms; consider splitting holdings across multiple custodians to avoid single-point-of-failure risk.

— Use custody as a toggle for family members or non-technical users, and combine custodial Bitcoin with insurance products (e.g., AnchorWatch) or exchange-native features (e.g., River Force Field) to reduce inheritance and theft risk.
