Is It the Altcoin Season in June?

2025-06-08

Cryptocurrency investors and enthusiasts frequently ask, “Is it altcoin season?”—especially as market cycles shift and new opportunities arise. Altcoin season, often called “altseason,” is a period when alternative cryptocurrencies outperform Bitcoin, attracting attention for their rapid gains and heightened volatility.

As June 2025 unfolds, understanding whether we are in altcoin season is crucial for traders seeking to optimize their portfolios and anticipate market trends. This article offers a comprehensive, data-driven look at the current state of the crypto market, the altcoin season index, and what signals to watch for the next altseason.

What Is Altcoin Season and How Is It Measured?

Altcoin season refers to a period when a significant number of altcoins (cryptocurrencies other than Bitcoin) outperform Bitcoin over a defined timeframe—typically 90 days. During these windows, capital tends to rotate from Bitcoin into altcoins, leading to substantial price increases and increased trading activity for non-Bitcoin assets.

The primary tool for measuring whether it is altcoin season is the Altcoin Season Index. This index, calculated by platforms like Blockchain Center and Bitget, analyzes the performance of the top 50 or 100 altcoins compared to Bitcoin over the last 90 days. The index uses a 0 to 100 scale:

Above 75: Altcoin season
Below 25: Bitcoin season
Between 25 and 75: Neutral or transition phase

Key factors influencing the index include:

The percentage of altcoins outperforming Bitcoin
Shifts in Bitcoin dominance (its share of the total crypto market cap)
Changes in trading volumes and volatility for altcoins
Social media sentiment and community activity

Is It Altcoin Season in June 2025? Latest Data and Analysis

As of early June 2025, the answer is clear: It is not altcoin season. Multiple reliable sources and the latest Altcoin Season Index readings confirm that the market is currently in a Bitcoin season.

The Altcoin Season Index, as reported by Blockchain Center and Bitget, is well below the altseason threshold. Only 26 to 28 of the top 100 cryptocurrencies have outperformed Bitcoin in the last 90 days, resulting in an index value around 22–28—far from the 75 needed to declare an altcoin season.
Bitcoin dominance remains high, recently peaking at over 63%, and Bitcoin’s price hit a new all-time high above $111,700 in late May 2025.
While some altcoins have posted strong gains, these have been isolated and not broad-based enough to shift the overall market dynamic.

What Triggers Altcoin Season? Key Indicators and Market Signals

Altcoin seasons are cyclical and typically follow major Bitcoin rallies. Several factors and signals can help anticipate the next altseason:

Bitcoin Price Stabilization: After a significant surge, Bitcoin’s price often consolidates. This period of stability encourages investors to seek higher returns in altcoins.
Declining Bitcoin Dominance: A sustained drop in Bitcoin’s share of the total crypto market cap is a classic precursor to altcoin season. When dominance falls below key levels (often below 54%), altcoins tend to gain momentum.
Rising Ethereum and Major Altcoins: A strong performance by Ethereum (ETH) and other leading altcoins can signal a shift in market focus.
Increased Altcoin Trading Volumes: Spikes in trading activity and liquidity for altcoins often accompany the start of altseason.
Positive Regulatory or Macro Events: Changes such as interest rate cuts, favorable political developments, or new crypto regulations can act as catalysts, prompting capital rotation into altcoins.

Currently, while Bitcoin has stabilized above $100,000 and Ethereum has seen gains, the broader market has not yet shifted decisively toward altcoins. Experts note that the conditions for altseason—such as a sharp drop in Bitcoin dominance and a surge in altcoin outperformance—are not yet present.

When Might the Next Altcoin Season Start?

Predicting the exact start of the next altcoin season is challenging, as it depends on a combination of technical, macroeconomic, and sentiment-driven factors. Historically, altseason tends to follow periods of Bitcoin price consolidation and declining dominance. Here are some scenarios that could trigger the next altseason:

Federal Reserve Interest Rate Cuts: Lower rates can drive investors toward riskier assets, including altcoins, seeking higher yields.
Major Regulatory or Political Events: Supportive regulatory changes or political wins (such as pro-crypto administrations) can boost confidence in altcoins.
Market Sentiment Shifts: As Bitcoin’s rally matures and enthusiasm for altcoins builds, a tipping point may be reached, leading to rapid capital rotation.

Some analysts suggest that the next altcoin season could emerge later in 2025, especially if Bitcoin’s dominance declines and macroeconomic conditions become more favorable for risk assets. Until then, the market remains in Bitcoin season, with altcoins lagging behind.

How to Use the Altcoin Season Index for Investment Decisions

The Altcoin Season Index is a useful tool for both new and experienced investors. Here’s how you can use it to inform your crypto strategy:

Identify Market Phases: Use the index to determine whether the market is in Bitcoin season, altcoin season, or a neutral phase. This can guide your portfolio allocation.
Time Entries and Exits: Entering altcoins early in an altseason can offer higher potential returns, while exiting or reducing exposure as the index peaks can help manage risk.
Diversify Strategically: During Bitcoin season, a higher allocation to Bitcoin may be prudent. As the index approaches altseason levels, gradually increasing exposure to altcoins can capture upside potential.
Monitor Sentiment and Volume: Combine index data with trading volumes, social media trends, and news to get a fuller picture of market sentiment.

Remember, the Altcoin Season Index is a lagging indicator—it reflects past performance. Use it alongside other technical and fundamental tools for a balanced approach.

Conclusion

In June 2025, it is not altcoin season. The latest data from the Altcoin Season Index and market analysis show that Bitcoin remains the dominant force, with most altcoins underperforming over the past 90 days. While some isolated altcoin rallies have occurred, the broad-based momentum needed for altseason is absent.

Investors should watch for signs such as falling Bitcoin dominance, rising altcoin volumes, and favorable macro conditions as potential triggers for the next altcoin season. Until then, strategic portfolio management and careful monitoring of market indicators remain essential.
