There are AI cex coins that are older ( $FET $AK etc) and some that are newer ( $GRASS $TAO $WLD)
Older ones are good in the sense that they have no unlocks left/high float. They're bad bc of less relevant tech, less relevant narratives / just older
Newer ones have more mindshare but unlocks. Pick your poison
(obv these are all way different than the onchain ones like AVA, ai16z, virtual, etc)
