Altseason Fair Value Band

Open this page

Is the altcoin market stretched against Bitcoin or cheap? This chart shows where the ratio sits compared with its own long-run average.

What it shows

  • The Altcoins/BTC ratio against a fixed long-run average, with an upper and a lower band around it.
  • A risk level from 0 to 100 that shows where the ratio sits between the bands.
  • Our own definition: the ratio excludes real-world-asset tokens.

It is context on where the ratio stands, not a signal. The chart is part of Plus. The guide in Learn explains how the bands are built and how to read them.

Altcoin Strength Index fix

The Altcoin Strength Index could read 0 because its daily update used a different market total than the history. Both now use one source, and the weekly close follows the Monday-to-Sunday week. Chart labels now say Altcoins/BTC.
