25 out
Conviction?How big this position is inside the typical holder's own portfolio (median, in basis points). 1 bps is pocket lint they will not miss; 200+ bps is a bet they did real work on. Many holders at tiny weight is weaker than few holders at real weight.

median holder weight: token bet
Streak?How many quarters in a row the active holder count has risen. Persistence, not a buy signal: long streaks are how names end up crowded.
