What is crypto market breadth?Market breadth measures how broadly a move is shared across the market — not just whether the index (Bitcoin) is up or down, but how many coins are participating. Strong bull markets typically show wide breadth (most altcoins outperforming BTC), while late-cycle or bear markets show narrow breadth (BTC holds up while alts underperform). The advance-decline ratio below 50% often precedes broader market weakness; a recovery above 60% breadth can signal strengthening risk appetite.

Frequently asked questions
What does "market breadth" measure on this page?
This page tracks what fraction of the top 100 cryptocurrencies by market cap are outperforming Bitcoin's price change over three windows — 24 hours, 7 days, and 30 days. Each coin is compared directly against BTC's return over the same window; the breadth score (0–100) is the percentage of coins beating BTC in that window.
How do I read the regime label, from "Bull Breadth" to "Breadth Breakdown"?
The 24-hour breadth score maps to one of five regime labels: Bull Breadth (70%+ of altcoins outperforming BTC — participation is wide), Advancing (over half outperforming — risk appetite broadening), Mixed (roughly split — indecisive), Declining (over half underperforming — capital may be concentrating in BTC), and Breadth Breakdown (under 30% outperforming — a Bitcoin-dominant or broad risk-off phase). These are descriptive labels applied to the live score, not predictions.
Why can market breadth diverge from Bitcoin's own price, and what has that historically signaled?
Breadth measures participation, not just direction — Bitcoin's price can rise while breadth narrows if gains are concentrated in BTC alone and altcoins lag, or Bitcoin can be flat while breadth widens as altcoins catch a bid. Historically, narrowing breadth during a BTC rally has been read as a late-cycle or risk-concentration signal, while widening breadth during BTC weakness has been read as broader risk appetite returning. This is a historical pattern description, not a forecast.
