Chapter 05
Adoption: who actually holds bitcoin
Awareness is nearly universal. Everyday payment use is still rare. Ownership sits in a band of surveys, and the largest new piles in the United States are not in pockets — they are in ETFs and treasuries.
United States
Pew Research (January 2026) found that about 19% of U.S. adults have invested in or used a cryptocurrency — close to the 16% Pew recorded in 2021. Use is higher among men and among adults under 50. That number is crypto, not bitcoin-only.
River’s mid-2026 research put bitcoin ownership at about 18.6% of U.S. adults (~49.6 million), and said more Americans reported holding bitcoin than gold. Other surveys land lower or higher depending on wording (“ever used” vs “currently own,” bitcoin vs any coin). Cornell’s 25-country study put current U.S. bitcoin ownership nearer 12% in its sample. The honest sentence is: tens of millions of Americans have touched it; a smaller set still hold it; almost nobody pays the grocery bill with it.
The ETF wrapper
U.S. spot bitcoin ETFs and related U.S. vehicles are tracked in the ballpark of 1.3 million BTC — on the order of 6% of the 21 million cap — with one fund holding well over half of that sleeve. That is how most advisors and model portfolios touch the asset.
Firms and the state
U.S.-listed companies hold most of the publicly disclosed corporate bitcoin. The U.S. government also holds a large seized stack (hundreds of thousands of BTC in commonly cited tallies). Seizure is not the same as a purchased reserve.
13F filings in 2026 showed professional holders trading the ETFs around: advisors more sticky, hedge funds and brokers more cyclical. Banks have begun appearing in the filings. Access through a brokerage is adoption of a product. It is not the same as running a node.
Who sits on the coins (mid-Sep 2026 snapshot)
Public trackers disagree by tens of thousands of coins. They use different entity lists and filing dates. This is an order-of-magnitude map, not a balance sheet. Do not add the rows — a company can also sit inside an ETF.
| Bucket | About | Share of 21M |
|---|---|---|
| ETFs and similar funds | ~1.3–1.5 million BTC | ~6–7% |
| Public companies | ~1.22 million BTC across ~180 firms | ~5.8% |
| Governments (disclosed) | ~650,000 BTC | ~3.1% |
| Private companies | ~280,000 BTC | ~1.3% |
Public treasury-tracker compilations dated 13 Sep 2026. Figures move with filings.
Corporations
One U.S. listed software-and-treasury firm holds about 845,000 BTC (~4% of the cap), accumulated since 2020. That is in a class by itself. The next public stacks are an order of magnitude smaller — typically tens of thousands of coins, not hundreds of thousands. Among the top 100 public holders, that single firm is often about two-thirds of the corporate pile. Concentration, not a broad Fortune 500 movement.
| Kind of firm | BTC (approx.) | Note |
|---|---|---|
| Largest U.S. public treasury company | 845,000 | ~4% of 21 million |
| Next U.S. treasury vehicle | ~43,500 | An order smaller |
| Largest widely cited stack outside the U.S. | ~40,000–43,000 | Japan-listed |
| Large U.S. miner treasuries | tens of thousands each | Some have also sold |
| A few familiar operating companies | ~9,000–12,000 each | Mostly flat for years |
Funds, endowments, pensions, sovereigns
Most of these hold shares of U.S. spot bitcoin ETFs, not coins on a corporate treasury. One asset manager’s year-end 2025 cut of professional 13F owners of those ETPs:
| Type | Share of reported professional ETP value |
|---|---|
| Investment advisors | ~42% |
| Hedge funds | ~28% |
| Brokerages | ~13% |
| Banks | ~3% |
| Sovereign wealth | ~2% |
| Endowments | ~1% |
- Endowments: Harvard Management Company held about 3.04 million shares of the largest U.S. spot bitcoin ETF (~$101 million) as of 30 Jun 2026, after two quarters of selling. Brown, Dartmouth, and Emory have also been listed as ETF holders.
- Pensions: the State of Wisconsin Investment Board (SWIB) was an early state-pension ETF holder. Roundups also name the Arizona State Retirement System, Michigan State Retirement, New York State Teachers, Ohio STRS, and Texas Teachers. CalPERS has been debated in public; wait for that fund’s own report before treating a size as fact.
- Sovereigns: Mubadala (Abu Dhabi) has been a large holder of the largest U.S. spot ETF (on the order of $490 million at 30 Jun 2026 in one report). Norway’s oil fund (Norges Bank Investment Management) is mostly indirect — equity in treasury companies — about 11,500 BTC-equivalent in H1 2026 by one shop’s math, not coins in Oslo.
- Foundations: they appear in the 13F “other” bucket. There is no clean public foundation list comparable to a treasury company’s periodic filing. The named university endowments above are the closest well-documented cousins.
Governments
| Holder | BTC (approx.) | How it got there |
|---|---|---|
| United States | 328,000 | Mostly seizures |
| China | 190,000 | Often cited as seized; opacity is high |
| United Kingdom | 61,000 | Criminal-justice holdings |
| El Salvador | 7,700–7,800 | Policy purchases; later donations per IMF language |
| Bhutan | ~5,000 | Hydro mining via the state investment arm |
A seized pile is adoption of enforcement, not of a monetary standard.
Private people
Most bitcoin is still held outside the named corporations and ETFs. The catch: an address is not a person. Exchanges, custodians, and funds look like “whales” on-chain.
Satoshi Nakamoto is the largest individual estimate. Early-miner clustering (“Patoshi”) is usually quoted between about 600,000 and 1.1 million BTC. Those coins have not moved since 2010. They sit with lost or dormant supply until they move.
Henley & Partners’ 2026 wealth note, converting large addresses into people, put Bitcoin millionaires on the order of 90,000 at end-August 2026 prices, and a central guess of about two dozen crypto billionaires — a wide range, because unnamed dormant stacks distort the count.
On-chain distribution as of mid-September 2026 (addresses, not identified humans):
| Address size | Share of supply (approx.) |
|---|---|
| 10,000+ BTC | 15% |
| 1,000–10,000 | 21% |
| 100–1,000 | 26% |
| 10–100 | 21% |
| 1–10 | 10% |
| Under 1 BTC | ~7% |
Addresses of 100 BTC and up hold about three-fifths of the coins. That band includes exchange cold storage, ETF custody, the largest corporate treasury, and Satoshi-era dumps — not thousands of secret tycoons.
Named living people almost never publish a full personal stack. What the public sees is usually an ETF line, shares of a treasury company they control, or an exchange balance they do not own. Retail holders are the survey respondents in Pew, River, and Cornell: tens of millions have touched bitcoin; far fewer still hold a meaningful balance; most of those hold it on an app.
Lost coins belong in this section. Long-dormant early addresses — including Satoshi’s — run into the millions of BTC. Those units exist. They are not circulating.
Worldwide
Cornell’s Bitcoin Adoption Index (25 countries, late 2024–early 2025 fieldwork) is a useful cross-section:
- 90% had heard of bitcoin.
- 13.2% said they currently own it; about 30% had ever owned it.
- Former owners outnumbered current owners in most countries surveyed — people try it and leave.
Current-ownership shares in that study were highest in places under monetary stress or with an official bitcoin story (El Salvador, Venezuela, Nigeria appeared at the top of “ever owned”). High-income countries often show high awareness and lower current ownership. That is the opposite of a simple “rich countries adopt first” slogan.
How owners said they hold it (Cornell, all countries): digital wallets first, then exchanges, then ETFs still a single-digit slice. Most holders are not self-custody purists. Most are also not using bitcoin as a weekly currency.
The legal-tender experiment
El Salvador made bitcoin legal tender in 2021. By 2025–26, under an IMF program, merchant acceptance was no longer mandatory, taxes were dollar-only, and the state Chivo wallet was being wound down or handed to a private operator. Retail payment use in national surveys fell from the early years into the single digits.
The government still discloses a reserve on the order of 7,700 BTC. The IMF’s later staff language treated additions after mid-2025 as donations rather than new public spending. Two facts can be true at once: a sovereign stack exists, and street use did not become the national payments system.
That is the adoption lesson that belongs next to Chapter 01. A law can put bitcoin on the books. Habit is slower. Dollar rails, fees, and volatility still win the checkout line.
What “adoption” should mean on this site
Count four layers separately or the word becomes marketing:
Awareness
Almost everyone has heard the name.
Ownership
A minority hold some, often through an app or an ETF.
Settlement
Who uses it to pay or remit. Still thin in the U.S. and thinner than the 2021 El Salvador headline.
Infrastructure
ETFs, bank custody filings, exchanges, Lightning. This layer can grow while street use stays small.
Bitcoinphile will treat a new ETF rule, a sovereign wallet disclosure, or a serious payments rail as adoption news. A celebrity ticker will not.
