The Evidence Table

|---|---|---|---|
| Altcoin Season Index90-day window, 50 altcoins | 56/100 | 75 or more favours altcoins; 25 or less favours Bitcoin. | Neutral |
| Short-term breadth7-day index 34 against 30-day 64 | -30 points | 7-day index more than 10 points above the 30-day favours altcoins; more than 10 below favours Bitcoin. | Favours Bitcoin |
| Bitcoin dominance levelBitcoin share of total crypto market cap | 59.26% | 42% or less favours altcoins; 55% or more favours Bitcoin. | Favours Bitcoin |
| Bitcoin dominance, 30-day changeFrom 58.42% thirty days earlier | +0.84 pp | A fall of 0.5 points or more favours altcoins; a rise of 0.5 or more favours Bitcoin. | Favours Bitcoin |
| Dominance excluding stablecoins, 30-day change66.42% today; needs 30 days of stored readings | — | Same 0.5-point rule, with stablecoin supply removed from the total. | Not enough history |
| ETH against BTC, 30 daysETH/BTC at 0.02979 | -6.0% | ETH ahead of BTC by more than 2% favours altcoins; behind by more than 2% favours Bitcoin. | Favours Bitcoin |
Thirty-day changes compare today with the nearest stored snapshot on or before the date 30 days earlier. A signal is left unmeasured, and out of the count, when the history does not reach back.
Market cap, volume and stablecoin share are context. They say how much money is in the market, not whether it favours altcoins or Bitcoin, so they are not counted above.
Agreement matters more than any one row
A single signal flips often. Breadth, dominance and ETH/BTC pointing the same way is the rarer condition.
The rules do not move
Each threshold is fixed and printed beside its reading, so a changed result always means the market changed.
A description, not a forecast
The table reports the latest snapshot. Signals can agree and then reverse, and none of this is investment advice.

On October 16, 2026, 0 of 5 measured signals favour altcoins, 4 favour Bitcoin and 1 are neutral. 1 signal is not yet measurable from the stored history.
Favouring Bitcoin: Short-term breadth; Bitcoin dominance level; Bitcoin dominance, 30-day change; ETH against BTC, 30 days.
Altcoin season is not confirmed. This tracker requires the index at 75 or more and Bitcoin dominance at 42% or less; today they read 56/100 and 59.3%.
Each row is a measurement with a fixed, published rule, so the table can be checked line by line. The signals describe the market as it stands in the latest snapshot. They are not a forecast, and several of them share inputs: both dominance rows start from the same Bitcoin market cap.
