Altseason

The stage of the market where money flows into altcoins rather than bitcoin, or from bitcoin to altcoins.

This often occurs after a major increase of a large crypto holding, and the holders of that asset are looking to spread out their earnings over multiple projects. This in turn can cause rapid increases to the lower-cap coins, causing an avalanche of new investment looking to join in on the gains. Or when TikTokers hype low-cap coins.
