What is the altcoin season index?

The altcoin season index is the share of the top altcoins that have done better than Bitcoin over the last 90 days.

How is the altcoin season index calculated?

Take the leading altcoins by market value, up to 50 of them, and count how many returned more than Bitcoin over the past 90 days. If 75% or more did, the market is in altcoin season. Below 25%, it is in Bitcoin season. In between, it is neither. The count is shown on the capital rotation dashboard.

What does altcoin season mean?

It describes where money has been flowing. In altcoin season, risk appetite has run toward smaller coins; in Bitcoin season, it has retreated to the largest one. Either way it describes the last 90 days, not the next.

What are the limits of the altcoin season index?

Every coin counts once, so a small coin's breakout weighs the same as a large coin's. The result depends on which coins are in the list, and the 75% and 25% lines are conventions rather than findings. A 90-day window also means the label changes well after the move that caused it.
