# Galaxy Research Finds 55% of Bitcoin Supply Remains Unattributed

Around 11.1 million BTC cannot be tied to known entities, underscoring the persistence of self-custody and lost coins despite institutional inflows.

## At a glance

- **What happened:** Galaxy Research reported that approximately 11.1 million BTC, or 55% of total mined supply, cannot be tied to any known institutional or exchange entity.
- **Why it matters:** The data demonstrates that retail investors and self-custodians still control a larger share of Bitcoin's supply than institutional custodians and funds.
- **Who is affected:** Bitcoin investors, onchain analysts, and institutional custodians.
- **What's next:** No next step announced.
- **Primary source:** [Over 11 million BTC can't be linked to any known owner](https://www.coindesk.com/markets/2026/10/26/over-11-million-btc-can-t-be-linked-to-any-known-owner-even-after-wall-street-buying) — coindesk.com

## Key points

- Galaxy Research found that 11.1 million BTC (55% of mined supply) sits in unlabelled addresses.
- The unattributed pool includes retail self-custody, lost early coins, and unmapped private funds or OTC desks.
- Known entities accounting for the remaining 45% include BlackRock ETFs, the US government, and 1,123,658 BTC in Patoshi pattern wallets.

## Editorial remark

- **Context:** Rapid institutional adoption and spot ETF approvals over recent years concentrated significant trading volume onto Wall Street platforms.
- **Impact:** Market liquidity may be thinner than total capitalization implies, as a majority of supply remains locked in private self-custody, lost wallets, or non-custodial storage.
- **Watch:** Galaxy Research and onchain intelligence desks monitoring wallet attribution shifts and movement within dormant or early Satoshi-era blocks.

More than half of all circulating $BTC cannot be linked to known institutions, centralized exchanges, or governments, according to an October analysis released by Galaxy Research [1]. The research arm identified approximately 11.1 million BTC—representing roughly 55% of the estimated 20.1 million mined coins—in unlabelled addresses [1]. At the time of writing, $BTC was trading at $79,982.

Galaxy's head of research, Alex Thorn, highlighted the data as confirmation that individual self-custody continues to dominate the asset's ownership structure despite extensive institutionalization [1]. Self-custody involves users retaining their own private keys rather than trusting third-party custodians or investment vehicles [1]. In response, Xapo Bank noted that the concentration of unattributed coins illustrates retail market dominance that predates institutional interest [1]. Understanding the distribution of unspent transaction outputs is central to tracking these movements, as seen in the mechanics of [Bitcoin UTXOs](https://basisdesk.news/news/bitcoin-utxos-explained).

## Unidentified Balances and Known Entities

The unattributed category encompasses several types of holders [1]. Galaxy pointed out that this segment likely contains permanently inaccessible or lost tokens from owners who misplaced keys or passed away [1]. It also accounts for early tokens mined outside the Patoshi pattern, non-attributed institutional holdings such as over-the-counter desks and private funds, as well as complex multi-address custodial architectures [1]. 

Conversely, Galaxy identified specific entities for the remaining 45% of the network's supply [1]. These labelled holdings include centralized exchanges, exchange-traded funds including BlackRock, and sovereign seizures by the US government [1]. Galaxy tracks early blocks associated with Satoshi Nakamoto separately, estimating the "Patoshi pattern" holdings at 1,123,658 BTC [1]. Despite substantial allocations into spot funds, anonymous and retail-managed balances remain the largest component of Bitcoin supply [1].
