Is Altseason Finally Here? Key Signals Every Crypto Investor Should Watch

Has the legendary altcoin season finally arrived? For years, traders have anticipated the moment when altcoins break free from Bitcoin’s shadow. With new market activity and shifting dominance, many are asking: Is altseason here in 2025?

By analyzing Bitcoin dominance, total market cap excluding Bitcoin (Total 2), and historical patterns, we can better understand where the market stands. Let’s break down the altcoin season indicators to determine whether we are witnessing the early stages of the next crypto bull run for altcoins.

Understanding Altseason

Altseason, short for altcoin season, is a market phase when altcoins significantly outperform Bitcoin. Historically, this period occurs when Bitcoin dominance drops sharply while the altcoin market cap (Total 2) breaks out above key resistance levels.

The middle of altseason typically features parabolic rallies in altcoins, coupled with Bitcoin dominance falling below 48%. The beginning of altseason usually aligns with Total 2 breaking past its previous all-time highs while Bitcoin dominance starts a consistent downtrend.

Current Market Signals

1. Bitcoin Dominance

As of now, Bitcoin dominance has started to decline from above 60%. A sustained drop could signal the flow of capital into altcoins. Historically, major altcoin rallies followed sharp Bitcoin dominance declines.

2. Total Market Cap Excluding Bitcoin (Total 2)

The Total 2 index currently sits below its last cycle’s all-time high of $1.6 trillion, standing around $1.44 trillion. While not yet at breakout level, the gap is relatively small. A surge of just $160 billion could push Total 2 past resistance—potentially igniting altseason.

3. Historical Cycle Alignment

Past altcoin seasons occurred roughly 1.5 years after Bitcoin halvings. With Q4 2025 approaching, this timing aligns closely with previous cycles, adding weight to the possibility that a new altseason is imminent.

4. Altcoin Season Indexes

Indexes from various crypto trackers suggest altseason may have already begun in September 2025. However, these indexes can be inconsistent, so they should be used cautiously alongside market data.

Conclusion

So, is altseason finally here? The answer is: not quite, but we’re very close. Bitcoin dominance is breaking down, which is the first major signal. However, Total 2 still needs to break its all-time high for confirmation.

For crypto investors, this means there’s still time to prepare portfolios before altseason fully kicks off. Once both conditions align, history suggests the crypto bull run for altcoins will move fast—and may peak before the end of Q4.
