Key Takeaways:

Altcoin Seasonal Index rises to 52

Reflects 52 out of top 100 crypto assets outperforming Bitcoin over 90 days

Indicates growing altcoin momentum relative to BTC

Data sourced from CoinMarketCap, reported by BlockBeats

The Altcoin Seasonal Index has climbed to 52, signaling a shift in market momentum toward alternative cryptocurrencies, according to data from CoinMarketCap reported by BlockBeats.

The index tracks how many of the top 100 cryptocurrencies by market cap have outperformed Bitcoin (BTC) over the past 90 days. A value above 50 suggests a trend toward altcoin dominance, meaning more than half of the tracked tokens delivered better returns than BTC during the period.

As of July 21, 52 altcoins have outperformed Bitcoin, pointing to increased investor interest in non-BTC assets. Analysts often interpret a rising Altcoin Seasonal Index as an early indicator of an altseason, where capital rotates from Bitcoin into higher-beta altcoins.

While the metric alone does not confirm a full-scale altcoin cycle, it highlights an important market dynamic—Bitcoin underperformance relative to mid- and large-cap altcoins—that traders and portfolio managers monitor closely.
