There’s only
so much to go around.

Every rectangle claims its share of the 21M maximum. The space is finite. The estimates are not final.

02 / The 50% threshold

When does retail
drop below half?

Retail’s estimated share is 69.9% of circulating supply as of 30 Oct 2026. Three buying rates. Three possible paths below half. These are scenarios, not predictions.

05 / Field notes

Hold on.
Who’s holding?

The language matters as much as the numbers.

A company is not a fund.

Balance-sheet bitcoin and assets held for fund investors describe different kinds of ownership.

Compare the structures ↗
Whose bitcoin is in a trust?

A fund manager’s name is not the same thing as ownership of the fund’s assets.

More records. Not always more buying.

Adding a company to the database raises the recorded total even if it bought its bitcoin long ago.

working.

Snapshot: 30 Oct 2026. Retail is the remainder after recorded companies, funds, governments and a 3.7M BTC loss assumption. It is not a direct measurement of individual ownership.

Fund coverage is partial. Government estimates are older and incomplete. Missing institutions can inflate the retail estimate.
