I noticed that the altcoin season index has risen to 31 in recent days.

It's not huge compared to the 75 threshold that really confirms an altcoin season, but it's still an interesting signal.
It means that about 31% of the top 100 cryptocurrencies (excluding stablecoins) have outperformed Bitcoin over the past 90 days.

The thing is, this index predicts nothing; it just confirms an ongoing trend.
But since Bitcoin has consolidated after its rise, and some sectors like Layer 2 solutions and DeFi are moving well, there's reason to watch closely.
Major investors are starting to look at altcoins more seriously.

For us traders, it means we should keep an eye on the composition of the performing altcoins.
Is it concentrated on memecoins or diversified?
And most importantly, we must remember that past performance does not equal future results.
The altcoin season index is just one tool among others, not a crystal ball.
It's worth monitoring closely in the coming weeks.
