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.
You are right this season is strongest shown by bitcoin well altcoin are right following that moment, next year could it be if there a big correction in bitcoin. which might come on big days in Christmas and New Year so alt season can be happened real aswell which we will see together. maybe respond in reverse otherwise alt season will have to wait longer maybe yeah.
