Recently, the Crypto Assets market has experienced a striking phenomenon: the alts index has fallen to its lowest point in two years. This change in the indicator has sparked the attention and discussion of market participants.

By reviewing the data from the past few years, we can observe an interesting pattern. Since 2019, the alts index seems to reach a low point around mid-year each year:

June 2019
June 2020
July 2021
June 2022
June 2023

And now, we have entered June 2025, and this pattern seems to continue. This periodic phenomenon raises a thought-provoking question: why does the altcoin index experience a trough in the middle of each year?

This regularity may reflect certain intrinsic mechanisms of the Crypto Assets market. It could be due to investor behavior, market sentiment, or other cyclical factors. Notably, the current index level suggests that we have not experienced a typical 'altcoin season' for a long time.

This periodic phenomenon may hold significant importance for investors and market analysts. It could provide a new perspective for predicting market trends, while also reminding us to follow the long-term trends and cyclical changes in the Crypto Assets market.

However, we should also take a cautious view of this model, as financial markets are always full of uncertainty, and past patterns do not necessarily predict future trends accurately. Market participants should consider multiple factors comprehensively, rather than relying solely on a single indicator or model.

Overall, the cyclical changes of the alts index provide an interesting perspective for us to understand the Crypto Assets market, and it is worth our continued follow and research.
