The altcoin season index has clocked 80, which shows the altseason has officially begun. Experts trust this metric to determine whether the crypto market is in a Bitcoin season or an altcoin season.
The current score of 80 shows that at least 75% of the top altcoins have outperformed Bitcoin (BTC) for the past 90 days. Several other factors also confirm it, and crypto investors look excited about it.

Bitcoin dominance has been falling since June 2025. However, some experts still believe we are in the pre-altseason phase. The difference of opinions doesn’t mean altcoins are not doing well. Those cryptos are soaring, and their investors are rejoicing in the performance.
Factors Showing the Altcoin Season Has Begun
Millions of people have invested their money in altcoins. Most of them wait for the altcoin season’s commencement because it is when they can scoop up exceptional gains. The altseason delivers even better profits than a Bitcoin-led bull run.
Has it begun? The following factors indicate it has commenced:
The Altcoin Season Index Has Surpassed the 75 Mark
As mentioned earlier, the current value of the altcoin season index is at 80. That’s five points above the 75 mark. It is the clearest statistical signal that most of the experts accept.
Bitcoin Dominance is Falling
Bitcoin is the most dominant and valuable cryptocurrency in the world. This crypto giant often holds a much larger share of the crypto market cap than the combined market cap of altcoins. As altcoins’ share in the cryptocurrency market cap increases, BTC dominance starts falling.

Bitcoin’s dominance has kept declining since June 2025. It came down from the June peak of 65.84% to the current value of 57.77%. That shows the capital is rotating into altcoins and investors are looking for higher risk-adjusted returns.
Emerging Altcoins are Performing Well
Altcoins like ETH, BNB, SOL, XRP, and ADA are well-established cryptos. They have huge market caps, but emerging altcoins are much newer. When they start gaining traction, it is an indication of an altseason.
Several mid-cap and small-cap cryptocurrencies are showing substantial gains. This trend supports the idea that altcoin season may be underway.
The Altcoin Season Index has surged, signaling a shift in market momentum toward altcoins. Their investors might reap impressive rewards soon!
Ethereum is Leading the Altcoin Rally
Ethereum is the leader of altcoins and is doing better than Bitcoin. The investor confidence is growing due to increased stacking and activity in Layer-2 blockchains.
ETH outperforming BTC has historically been an early sign of the beginning of an altseason. The altcoin season index validates that; thus, it has officially begun.
Who Might Lose Money in This Altseason?
Do people lose money when altcoins are soaring and the market is in an altseason? Yes, they do! Soaring altcoin season index boosts every crypto investor’s confidence levels.
The altseason hype on social media platforms like X (formerly Twitter) further encourages crypto enthusiasts to go for significant gains.
Most people don’t realize that there are also times when retail investors lose a lot of money in an altseason. Crypto investors chasing pumps may invest in a token already 150-200% up. This FOMO can lead to significant losses.
Investors with no exit strategy, over-diversified portfolios, and leverage addiction might lose more than they earn in this altseason.
