Altcoin Season Index

The Altcoin Season Index measures how many of the top 100 coins by market value, leaving out stablecoins and wrapped or staked tokens, did better than bitcoin over a set window, as a percentage. The standard window is 90 days.

How to read it. A score of 75 or more is called Altcoin Season and 25 or less is called Bitcoin Season; anything between is neutral. It counts the past window only and is not a forecast. The window and the source are stated beside each reading.

Frequently asked questions

What is altcoin season?

It is a period when most large altcoins do better than bitcoin. The index puts a number on it: the share of the top 100 coins that beat bitcoin over the window.

Which window and source does this page use?

The standard 90-day reading is not available right now, so this page shows a 30-day reading from CoinGecko, computed by InvestIn.News as a stand-in. It is a different measure from the 90-day index and is labelled as such.

Is this the same number as on other sites?

It can differ. Providers use different coin lists, exclusions and windows. This page states the window and source of the number it shows.
