This chart represents the Altcoin Season Index. It is used to visualize whether the crypto market is favoring Bitcoin or altcoins (alternative cryptocurrencies to $BTC ).
๐ How to interpret it?
Y-axis (vertical):
Range from 0 to 100:
0โ25: Bitcoin dominance. This is known as Bitcoin Season.
25โ75: Neutral or transition zone.
75โ100: Altcoin dominance. This is called Altcoin Season.
X-axis (horizontal):
Timeline, in this case from September 2024 to July 2025.
๐ What does the black line show?
The line represents the current value of the index over time. This index is calculated by taking the top 50 altcoins (excluding BTC and stablecoins) and measuring how many have outperformed Bitcoin over the past 90 days.
๐ก Chart Reading:
Peak in November 2024 (~index 90+):
Many altcoins were outperforming Bitcoin โ Clear Altcoin Season.
January to June 2025 (~index <25):
Bitcoin dominated performance โ Bitcoin Season.
July 2025 (current, ~49):
Middle zone. Some altcoins are outperforming Bitcoin, but not enough to call it "Altcoin Season" yet.
โ Current Conclusion:
We are coming out of Bitcoin Season and moving toward a possible return of Altcoin Season, but it is not yet definitive.
The value of 49 suggests a transition: investors could start rotating out of Bitcoin and into altcoins if the trend continues.
