Over half of Bitcoin’s supply sits in wallets with no known owner

Galaxy Research identified that about 11.1 million BTC, representing 55 % of the roughly 20.1 million mined coins, are held in addresses that cannot be linked to exchanges, funds, governments or other known entities. The firm’s head of research, Alex Thorn, said the figure suggests that self‑custody by individuals remains widespread despite growing institutional participation. The unidentified holdings may also include lost coins, institutional wallets that Galaxy has not identified, or assets spread across complex custody structures.

Thorn’s analysis implies that retail investors may still control a majority of Bitcoin, which could affect expectations about future demand for custodial services and exchange‑based trading. The large share of unattributed coins also signals that any shift in self‑custody behavior could materially impact market liquidity.
