Supply concentration and top-10 share

Concentration measures how much of the supply the largest holders control.

The headline is the top-10 share: the percentage of the supply held by the ten largest wallets.

Infrastructure wallets are left out first. Leaving an exchange wallet in would count thousands of customers as one giant holder and distort every share.

The card shows the latest day as rings of holder rank (the top 10, ranks 11 to 50, 51 to 100 and everyone else) and the top-10, top-50 and top-100 shares as daily lines.

1. 1

   Each stored day carries the top-10, top-50 and top-100 shares (percent of supply), and the bands between them.

   ranks 11–50 = top 50 − top 10 · ranks 51–100 = top 100 − top 50 · everyone else = 100 − top 100
2. 2

   The supply layers (3D) stand a slab per day, its four bands stacked from zero to the whole supply with the top 10 at the bottom, so a layer thickening along the block is that group holding more and the layers' edges are the top-10, top-50 and top-100 shares.

3. 3

   The change is the top-10 share's move from the first to the last stored day, in percentage points. The key figure and the card both show it.

HighShape, not data

A few wallets hold much of the supply: their decisions move the market more, and the grade's concentration pillar reads it as structural risk.

LowShape, not data

The supply is spread across many holders.

RisingShape, not data

The largest wallets are adding. The signal rules count it as bull evidence (size accumulating); the card marks it in the negative colour, because concentration risk grows.

FallingShape, not data

The largest wallets are letting supply go to the rest of the market. The card marks a falling share in the positive colour; the rules count it as bear evidence.

Evidence in the data, never advice

• The two colourings answer different questions: the card's colour is about structural risk (less concentration is better), the signal rule's direction is about who is accumulating.
• A one-day step of many points is usually a reclassification, not trading.
• Shares are of the tracked supply after infrastructure is excluded, so they are not the same as a block explorer's top-holders list.
