The whole market,
three honest numbers a day.
The board ranks coins; this page measures the sea they swim in. Three daily series over a fixed liquid universe (median 30-day volume of $5M or more, pegged assets excluded): how broad the advance is, whether alts are beating bitcoin, and how far apart the winners and losers sit. Full history, published rules, no forecasts. Decisions are yours.
Breadth: how broad is the advance?
The share of liquid coins above their own 50-day average. The regime dial reads a version of this over the board's top-100 with fixed thresholds; the dial page holds that instrument. This is the same idea over the defined liquid universe, with its whole history. The breadth explainer covers why breadth, not price, is often the first thing to turn.
Alt season: are alts beating bitcoin?
The share of liquid non-BTC coins whose 90-day return beats BTC's. The market's convention calls 75% and above alt season, 25% and below BTC season. Today: 51.6%, mixed, between the season conventions. Alt season, measured is the full treatment, including why the threshold is a convention and not a switch.
Dispersion: does selection matter right now?
The interquartile range of 30-day returns: the gap between the market's 75th and 25th percentile coin. Low dispersion is a market moving as one block; high dispersion is a stock-picker's tape where holding the wrong coin costs real points. Shown with the median 30-day return for context.
Sectors today: where the momentum sits
The liquid universe grouped by primary CoinGecko sector, ranked by the sector's median 30-day return. A measurement of today's cross-section (the sector cache refreshes weekly); no sector history is claimed yet, it accrues from here.
| sector | coins | median 30d | breadth |
|---|---|---|---|
| DeFi | 5 | +11.2% | 60% |
| Layer 1 | 13 | +1.9% | 30.8% |
| Memes | 4 | -8.2% | 25% |
| AI | 5 | -13.6% | 40% |
Dominance: bitcoin's share of the pile
BTC's (and ETH's) share of the considered top-250 market cap after the published exclusions, measured once a day at publish time. No vendor gives this history for free, so Koryu accretes its own: the series starts 2026-07-19 and grows one honest point per day, with no backfill claimed. The dominance explainer covers what rotation in this number has historically meant.
The chart appears once the series has more than one day. Day one of the forward record is above; tomorrow adds the second point.
Universe: Liquid coins: med 30d quote volume >= $5,000,000, pegged/wrapped excluded, MA50 defined. A fixed rule, not the drifting market-cap top-100. Caveat: History is the published formulas recomputed over CURRENT listings (the local store is survivor-only), so early readings are indicative; the definitions are exact throughout. Data: Binance USDT spot daily klines (completed UTC days), local store. Measured through 2026-07-18. Research, not advice.
Questions
What is crypto market breadth?
The share of liquid coins trading above their own 50-day moving average. High breadth means the advance is broad; low breadth means a few names (usually BTC) are carrying a market whose average coin is falling. Koryu computes it daily over a fixed rule: every coin with at least $5M median 30-day volume, pegged assets excluded.
What is the alt-season measurement?
The share of liquid non-BTC coins whose 90-day return beats BTC's. The convention the market uses: above 75% is called alt season, below 25% BTC season, between is mixed. Koryu publishes the share and the thresholds as a convention, not a signal: the reading describes the last 90 days and predicts nothing.
What does dispersion tell you?
The gap between the market's winners and losers: the interquartile range of 30-day returns across the liquid universe. When dispersion is low, most coins move together and selection matters little; when it is high, which coin you hold matters enormously. It is a description of cross-sectional spread, not a tradable signal.
How far back does the history go, and can I trust it?
The definitions are exact for every day shown, but the history is the published formulas recomputed over currently-listed coins, because delisted coins are absent from the local store. Early readings are therefore indicative rather than point-in-time exact. The daily forward readings accrue against the live universe from publication onward.
Is any of this a buy or sell signal?
No. These are measurements of the market's current state under fixed, published rules. They carry no instruction and no forecast. Decisions are yours.
