Overall this year isn't alt season. Though defi project was doing great at the beginning. But finally bitcoin showed the strongest move in this year. And altcoins also got a slight good move. Compare to btc this is nothing good. Maybe next year would be the perfect alt season.
There no enough time this year for altcoins, bitcoin could reach a new level of success by achieving a new ATH but altcoins will not just easily follow. Altcoins season is pretty much for most legit altcoins, they will rise with significant amount like before, and we need a FOMO for that.
