There has been a lot of chatter lately about the possibility of an altcoin season on the horizon but the numbers simply don’t back it up yet.
While some altcoins are indeed doing very well and pulling in fresh capital, the overall market hasn’t yet seen the kind of widespread enthusiasm that usually comes with a proper altcoin season.
Bitcoin still accounts for about 60% of the cryptocurrency market, and Ethereum generally seen as the gateway to all the other altcoins, still hasn’t started to see the kind of capital inflows that marked previous bull cycles.
Only a Handful of Altcoins Are Really Rising
At first glance, the case for altcoin season looks convincing.
The OTHERS/BTC ratio which tracks how altcoins are doing relative to Bitcoin, climbed over 6% in the second quarter so far. May alone saw a gain of almost 15% which suggests investors are looking to spread their bets beyond just Bitcoin in search of higher returns.
Yet the rest of the market isn’t following suit. According to data from BlockchainCenter, the Altcoin Season Index fell by over 10% back in May remains firmly below the level required to confirm a genuine altcoin season.
Current readings remain in Bitcoin Season territory, with only a minority of major altcoins outperforming BTC over the past 90 days.
This explains the contradiction many traders are noticing. Money is flowing into some altcoins, but not enough of them.
Instead of a broad rally, capital is concentrated in just a few of the standout performers.

Bitcoin Continues to Dominate the Market
Bitcoin’s strength remains one of the biggest obstacles to a full altcoin season.
Despite ongoing volatility, Bitcoin has gained over 6% in the second quarter while many large-cap cryptocurrencies remain negative for the same period.
Bitcoin dominance has also stayed near 60%, reflecting investors’ continued preference for the largest digital asset.
In past cycles, major altcoin seasons have emerged when Bitcoin dominance declined, allowing money to start flowing out to the smaller assets.
A lot of analysts point out that the institutional money coming in through exchange-traded funds is favoring Bitcoin and so a lot of the new money coming into the market is concentrated on BTC rather than moving deeper into the risk curve.
The outcome is a market where individual altcoins can rally, but the wider sector struggles to gain momentum.
Ethereum Remains the Missing Piece
If there is one asset traders are watching for confirmation of altcoin season, it is Ethereum.
Ethereum is still a long way behind its previous cycle peak, about 60% down, and the difference between that and the growth that helped drive previous altcoin rallies is wide.
More importantly, on-chain activity shows that capital has not returned to Ethereum’s decentralized finance ecosystem at the scale many investors expected.
Data from DeFiLlama shows Ethereum’s total value locked (TVL) has dropped back down to the $40 billion level, a zone last seen in early 2024. Stablecoin supply on the network also remains roughly $6 billion below its previous peak of $166 billion.
These numbers are important because Ethereum is still the biggest DeFi ecosystem and acts as the default destination for investors for speculative capital during risk-on periods.
Without any decent inflows into ETH and its surrounding ecosystem, it becomes harder to sustain the altcoin season.

Hyperliquid’s Rally Shows the Market’s Current Reality
One example frequently cited by analysts is Hyperliquid (HYPE).
The token has continued to post strong gains and attract attention from traders.
However, that strength has not spread across the wider altcoin market. Investors are instead choosing to put their money into specific narratives while avoiding broad exposure to the sector.
This selective investing is a big part of the explanation for why the OTHERS/BTC ratio is looking better while the Altcoin Season Index is still weak.
Investors are rotating their cash but only into a small group of potential winners.
Conclusion: What Would Really Confirm Altcoin Season?
If a real altcoin season is going to happen, a few important conditions need to come together.
Bitcoin would need to lose some of its dominance, Ethereum would need to start attracting more capital, and a larger percentage of altcoins would need to outperform BTC over an extended period.
Until then though, the whole market appears stuck in limbo.
The rising OTHERS/BTC ratio shows that investors are becoming more willing to take risk, but weak Ethereum DeFi activity and persistent Bitcoin dominance suggest that enthusiasm remains concentrated rather than widespread.
For now, altcoin season remains more of a possibility than a reality.

Frequently Asked Questions About Altcoin Season
What is altcoin season?
Altcoin season is a period when most of the cryptos outperform Bitcoin over a decent stretch of time, often along with Bitcoin’s dominance level going down.
Why is Bitcoin dominance important?
Bitcoin dominance is how big a share of the whole crypto market Bitcoin actually is. A declining dominance level often signals capital rotating into altcoins.
Why does Ethereum play an important part in altcoin season?
Ethereum is home to the largest DeFi ecosystem. When capital flows into Ethereum and DeFi, it tends to help more of the altcoins follow suit.
What does the OTHERS/BTC ratio measure?
The OTHERS/BTC ratio tracks the performance of altcoins relative to Bitcoin and helps identify whether capital is rotating beyond BTC.
Has the altcoin season started yet?
Current data suggests no. While some altcoins are outperforming, the Altcoin Season Index and Bitcoin dominance indicate the market remains closer to Bitcoin Season than a broad altcoin rally.
