The Future of Bitcoin Banking | ALEX LEISHMAN

— River's origin story: Alex Leishman discovered Bitcoin through Austrian economics and the works of Hayek, then through a Coursera class taught by Balaji Srinivasan in 2013. He studied cryptography at Stanford and worked at Polychain Capital before founding River to build a Bitcoin bank rather than a trading exchange.

— Bitcoin bank vs. crypto exchange: River deliberately chose to remain Bitcoin-only and custody-focused, rejecting the higher-margin altcoin and trading path that Coinbase pursued. Leishman argues exchanges prioritize trader relationships while banks build longer-term client relationships and can cross-sell services.

— Custody model philosophy: River self-custodies client Bitcoin rather than outsourcing to third-party custodians like Prime Trust. Leishman emphasizes that the core custody skill is computer security and key management, not regulatory compliance or financial credentialing.

— Why self-custody exists: Leishman reframes the Bitcoin ethos as requiring the *option* to self-custody (protecting the invariant of no single point of control), not requiring everyone to self-custody. A small percentage of radical self-custodians create cultural accountability and shame institutions that restrict withdrawal rights.

— Custody failures (Prime Trust, Celsius, FTX): Root causes were operational mistakes (lost keys) and moral hazard (rehypothecation, fraud), not legal or regulatory gaps. Proof of reserves and transparency reduce the incentive for custodians to operate dishonestly.

— Decentralized lending vs. centralized banking: DeFi lending offers lower rates but introduces smart-contract risk. Institutional actors avoid on-chain DeFi for large loans due to protocol risk; centralized lending will likely dominate for Bitcoin borrowing long-term.

— When evaluating a Bitcoin custodian, prioritize demonstrated computer security competence and operational excellence over regulatory labels or qualified-custodian status. Ask what can go wrong—lost keys, hacks, theft, fraud—and who is proving those risks are minimized.

— Consider custody diversification if the risk of total reliance on one institution concerns you, but verify that alternatives actually reduce *different* risks rather than concentrating the same risks elsewhere.

— Proof of reserves and transparency in custody practices meaningfully raise the operational cost and reputational cost of dishonest behavior; look for custodians publishing proof of reserves and liabilities.
