Will There Still be a 2025 AltSeason?

Altseason, short for “altcoin season,” is the phase when altcoins significantly outperform Bitcoin, often delivering 10x–100x gains in weeks. Investors watch for this shift because it historically marks the most profitable part of every bull cycle. 

In late 2025, with Bitcoin trading near all-time highs and altcoins still far below their 2021 peaks, many are asking: Is the 2025 altseason still coming, or did we miss it?

Signs That Altseason 2025 Is Still Loading

Popular crypto analyst Merlijn The Trader recently shared an updated version of his widely followed Altcoin Cheat Sheet. 

The chart, which tracks the total market capitalization of all altcoins excluding Bitcoin and stablecoins, reveals that today’s price action is mirroring the exact setup that preceded every major altseason of the previous cycle in 2019, 2020, and early 2021. The repeating pattern is unmistakable and has investors paying close attention.

The Three Distinct Phases

first, a rejection at a multi-year horizontal resistance level (shown in red), followed by a controlled pullback, and then an extended period of sideways compression inside the green “ignition zone.”

Once compression ends, the market has always broken upward into a powerful vertical rally. In November 2025, altcoins are sitting squarely inside that ignition zone, behaving almost identically to past cycles.

Key Indicators Supporting a 2025 Altcoin Rally

Several on-chain and market metrics are flashing bullish for altcoins:

• Bitcoin dominance dropped from 65% in May 2025 to around 58–60% in November

• Altcoin Season Index rising from the low 30s toward 50 (75+ confirms full season)

• Record whale accumulation in ETH, SOL, XRP, and LINK

• Exploding trading volume in AI, RWA, and DePIN sectors (up 500–700% year-over-year)

• Retail sentiment at extreme fear ,  classic contrarian buy signal

These signals mirror conditions right before the massive 2021 altseason.

Top Altcoins to Watch for the Upcoming Season

Not all altcoins will pump equally. Analysts recommend focusing on projects with strong fundamentals and active narratives:

• Ethereum (ETH) – ETF inflows and Layer-2 scaling

• Solana (SOL) – fastest growing ecosystem in 2025

• XRP – regulatory clarity and cross-border payment adoption

• SUI & ONDO – leaders in DeFi and real-world assets

• AI tokens (FET, RNDR, TAO) – hottest narrative of the cycle

Positioning early in these leaders has historically delivered the highest returns.

Risks That Could Delay or Weaken Altseason 2025

While the technical picture looks promising, real challenges exist. More than $59 billion in token unlocks are scheduled through 2026, which could create selling pressure. 

Global interest-rate policy remains uncertain, and any pause in liquidity expansion might delay the breakout. 

Additionally, the market has matured, Bitcoin and Ethereum now capture most institutional flows, so a broad 2021-style rally across thousands of coins is less likely. Instead, expect a more selective, narrative-driven season.
