More Than Half of Bitcoin Still Has No Known Owner—and Wall Street Hasn’t Changed That

Bitcoin’s ownership map still looks nothing like a Wall Street registry.

About 11.1 million BTC—roughly 55% of the bitcoin mined so far—sits in addresses that Galaxy Research could not connect to an exchange, fund, government or other known entity in its October snapshot, according to CoinDesk.

That is a striking result after years of spot ETFs, public-company treasury purchases and institutional custody deals. The largest share of the supply is still the share researchers cannot confidently name.

Galaxy’s attributed bucket covers recognizable exchanges, spot ETFs, government holdings and the Satoshi-era miner pattern. The research therefore compares a large known institutional layer with an even larger group whose owners cannot be established from current address labeling.

The report also makes clear that the unknown group is mixed. It may contain self-custodied retail coins, inaccessible early wallets, unidentified professional holders and custody arrangements spread across multiple addresses.

Unattributed does not mean lost

The first caution matters: “unknown owner” is a classification, not a verdict.

Some of those coins probably belong to individuals holding their own keys. Some may be stranded in wallets whose owners lost access.

Others could belong to institutions, funds or over-the-counter trading desks that have not been identified. Sophisticated custody systems can also divide assets among many addresses, making a single owner harder to spot from public-chain data.

In other words, the figure does not prove that 55% of Bitcoin belongs to ordinary retail holders. It does show that institutionalization has not made the network’s ownership transparent in the way a corporate cap table is transparent.

Galaxy Research head Alex Thorn highlighted that tension directly. His reading is that the still-enormous unattributed share points to widespread self-custody even after years of centralized platforms and Wall Street products.

more than half of all BTC supply is sitting in addresses with no known attribution

despite all the institutionalization and centralized ownership over the years, still a ton of bitcoin (maybe even most) is held by individuals in self-custody 🔐 pic.twitter.com/OYGFMuQVvQ

Bitcoin’s retail-first history still matters

Bitcoin did not begin with an ETF prospectus or a bank distribution agreement. Individuals mined it, traded it and learned to secure private keys years before major asset managers arrived.

Xapo Bank framed the unattributed supply as evidence of that bottom-up history: retail holders were in the market for more than a decade before institutions started treating bitcoin as a mainstream portfolio asset.

And why bitcoin is for the people and people 'can be their own bank'

Retail have been here for over a decade. Everyone else still catching up.

Self-custody is the part of Bitcoin that makes this possible. A holder who controls the private keys can hold and move coins without leaving them in an exchange account or through a fund share.

The ledger shows the address and balance, but it does not automatically reveal the person or organization behind it.

The other 45% is increasingly institutional

Galaxy was able to associate the remaining portion with known holders and services. That group includes exchanges, spot ETFs led by BlackRock, the U.S. government and the Satoshi-era miner pattern, which Galaxy treats separately and estimates at more than 1.1 million BTC.

Those names matter because they show how much of Bitcoin’s supply has moved into recognizable structures. But the comparison also puts Wall Street’s footprint in perspective.

Institutional ownership may be growing quickly without being close to the whole market.

The practical takeaway is not that researchers know who owns the unattributed coins. They do not.

It is that Bitcoin can absorb institutional products while preserving a vast, difficult-to-map layer of direct ownership.

That is a feature investors should understand, not a statistic to oversell. The same privacy-by-pseudonymity that protects ordinary holders also leaves room for lost coins, hidden institutions and imperfect analytics.

Still, after every headline about centralization, the biggest bucket remains the one without a name attached.
