Wall Street facilitates bitcoin whales’ shift from self-custody

Wall Street firms and custodians are increasingly moving large bitcoin holders away from self-custody by offering institutional-grade custody, OTC liquidity, and prime brokerage services. Whales are drawn by lower custody complexity and costs, access to leverage and yield products, and regulatory-compliant structures. The net effect is a growing concentration of on-chain BTC under regulated custodians, boosting liquidity and institutional inflows but reducing privately controlled supply. That centralization raises systemic and counterparty risks—greater potential for forced liquidations, censorship, or regulatory intervention—even as it supports price discovery and mainstream adoption.
