Grade pillar: concentration

The concentration pillar scores how much of the supply sits with the largest holders, the same top-10 share the concentration card draws, after infrastructure is excluded.

Its detail line names the top-10 share and its move over the window, a label for the pattern, such as stable, healthy dispersion, accumulation or whale distribution, and whether proven smart-money wallets are among the top 10.

A very concentrated top 10 can also act as a gate, which caps the letter whatever the composite.

1. 1

   The backend scores the pillar from 0 to 100, against the fleet, and records a one-line reading beside the score. A pillar it couldn't measure has no score and a reason instead: it is dropped, never scored zero.

2. 2

   The grade card places the score on a 0–100 track against the fleet: the median score across every cached token (a tick) and the middle half, the 25th to 75th percentile (a band).

HighShape, not data

Supply is spread wider than the typical token's.

LowShape, not data

Supply is more concentrated than typical, which the grade reads as structural risk.

RisingShape, not data

Concentration eased at the last grading.

FallingShape, not data

Concentration grew at the last grading.

Evidence in the data, never advice

• 50 is the fleet's typical token, not a pass mark: a 45 is a little below typical, not a fail.
• The detail line is the backend's evidence for the score; the card shows it in the data table and the hover.
• Scores are as of the last grading (the read holds no history of them).
• A high top-10 share can cap the grade through a gate whatever the other pillars score.
