Signs of the alt season:

1. Declining Bitcoin Dominance: If BTC's share of the total crypto market cap is falling, it may indicate the beginning of the alt season.

2. Rising Large-Cap Altcoins: Large altcoins like Ethereum start to rise first, and then the trend shifts to smaller-cap altcoins.

3. Increasing Altcoin Trading Volumes: When altcoin trading volumes start to increase significantly, it may signal the beginning of the alt season.

4. Positive Project News and Updates: Active development and positive events in the ecosystems of various altcoins can boost investor interest.

When to Expect the Alt Season?

The exact moment when the alt season will begin is difficult to predict, as it depends on many factors: current market conditions, the macroeconomic situation, and investor sentiment. Alt seasons typically come after a significant rise in Bitcoin, when investors begin to look for opportunities for greater growth in other assets.
