Galaxy Research Counts 11.1 Million Bitcoin (BTC) in Unattributed Addresses

Galaxy's October Supply Snapshot

Bitcoin ($BTC) has spent 2026 winning acceptance on Wall Street, yet most of its supply still answers to nobody on-chain. Galaxy Research's October supply snapshot classifies about 11.1 million $BTC, roughly 55% of the approximately 20.1 million coins mined to date, in addresses the firm cannot link to an exchange, fund, government or any other identified entity. At the time the data was compiled, the Bitcoin price stood near $84,459. Unattributed does not mean ownerless: it means an address has not been matched to a name, a distinction that shapes everything that follows. Galaxy's head of research, Alex Thorn, reads the figure as evidence that self-custody, holding your own private keys rather than leaving coins with an exchange or a fund, remains far more common than the institutional era suggests. "More than half of all $BTC supply" sits in addresses with no known attribution, Thorn wrote on X, adding that a large share of it is still "held by individuals in self-custody." Xapo Bank, a bitcoin-focused bank, offered a warmer reading in a reply on X: unnamed wallets are the footprint of a market that grew from the bottom up, and retail participants have "been here for over a decade" while "everyone else" is still catching up. Both posts appeared on Monday, 2026-10-26. The finding cuts against the narrative of the past two years, in which ETF launches, corporate treasuries and government seizures dominated the headlines. Attribution firms like Galaxy build the ownership map by clustering addresses tied to known exchanges, funds and large holders; whatever they cannot name lands in the unattributed bucket, and that bucket is now the largest single slice of the supply. Galaxy itself flags that the total may also include coins whose owners can no longer reach them, a caveat we unpack below.

Lost Keys, OTC Desks and the Patoshi Stack

The unnamed 55% is not a census of individual holders, and the snapshot cannot separate self-custody from several other categories mixed into the same bucket. Some of those coins are probably lost: wallets whose owners forgot their keys or died without passing on access, the situation crypto wallet recovery guidance addresses. Others were mined in bitcoin's earliest years by miners other than the one behind the Patoshi pattern, the set of early blocks researchers tie to a single miner widely assumed to be Satoshi Nakamoto. The bucket may also contain institutions Galaxy has not identified, including funds, companies and OTC desks, brokers that arrange large trades privately away from exchanges. Custody structure adds a further layer: one holder can spread coins across many addresses, the way an HD wallet generates a fresh address for each transaction, which makes clustering harder. For individuals who do hold their own keys, storage runs from a crypto wallet app on a phone to a hardware wallet kept offline as a cold wallet, and the risk profile of each arrangement differs sharply. The remaining 45% does carry names. It spans exchanges, spot ETFs led by BlackRock, the US government and the largest single identified holder, listed as the Satoshi Nakamoto (Patoshi pattern) cluster at 1,123,658 Bitcoin ($BTC), which Galaxy counts separately as the Satoshi-era miner pattern. Attribution rests on clustering addresses known to belong to exchanges and large holders, where ownership is documented through KYC records; coins outside those clusters stay unnamed. The ledger itself reveals balances and transaction history but never the person behind an address, so the unattributed total cannot be read as selling pressure any more than as retail conviction. It is a map of what is traceable, not a list of who owns each coin.

A Ceiling, Not a Census

Our reading is that the 55% figure functions as a ceiling on how far institutional capture has actually reached, not proof of retail dominance. Because the unattributed bucket blends self-custodied coins with likely lost supply, unnamed funds and fragmented custody, neither Thorn's thesis nor an "immovable supply" bull case can be proven from this snapshot alone. What it does establish is that ETF-era headlines describe a minority of the ledger: after BlackRock's funds, government holdings and every named exchange, identified holders still account for roughly 9 million of the 20.1 million coins mined. The number to watch in coming quarterly snapshots is the direction of the unattributed share itself, since each newly labeled cluster shrinks it without moving a single balance on-chain.
