What it means

The three zones

Bitcoin season 0–25
Bitcoin did better than most altcoins. It usually happens when the market falls or is fearful, and money moves to the "safest" coin.
Neutral 26–74
Neither dominates: some altcoins did better and some worse than Bitcoin.
Altcoin season 75–100
Three quarters of the top 50 did better than Bitcoin. It usually comes late in a rising market, when gains move from Bitcoin to smaller coins.

FAQ

What is the Altcoin Season Index?

A number from 0 to 100: the share of the 50 largest coins that did better than Bitcoin over the last 90 days. From 75 up it is "altcoin season", from 25 down "Bitcoin season".

Which coins count?

The 50 largest by market cap, without Bitcoin itself, stablecoins and tokens that just follow another coin, such as WBTC or stETH.

When is it updated?

Once a day, early in the morning (Greek time), with CoinGecko's closing prices.

Why does it differ from other sites?

Each site leaves out its own list of coins and uses its own prices, so the number may differ by a few points. The method is the same: top 50, 90 days, against Bitcoin.

Is the history exact?

For past days we use today's top 50. A coin that was in the 50 then but dropped out does not count, so the history is indicative.

Is it a buy or sell signal?

No. It shows what happened over the last 90 days, not what will happen. It is market information, not investment advice.
