Altcoin Season 2025: Is the big wave approaching?

In the crypto world, each market cycle is like a wave. Bitcoin is always the pioneering wave, strong and authoritative. But after it crashes to the shore, new altcoin waves make the market vibrant and chaotic. That moment is what people call Altcoin Season.

So, will 2025 be the year of altcoins?

The reality shows that Bitcoin dominance has decreased from 65% to 57-59%, paving the way for altcoins to shine. The market capitalization of altcoins also increased by over 50% in Q2, reaching 1.4 trillion USD. The ETH/BTC ratio has risen by over 60%, reflecting the increasing strength of Ethereum and foundational projects. However, the Altcoin Season Index (ASI) is still only around 40-50/100, lower than the 75 threshold to confirm a true altseason. This means that the prelude has begun but the climax has yet to start.

Nevertheless, many important trends have emerged. Layer-2 solutions like Arbitrum, Optimism, and zkSync have become the 'highways' for Ethereum. AI tokens and DePINs like RNDR and FET are standing out due to the global technology storm. RWA opens a bridge between blockchain and traditional finance, while meme coins continue to stir up crowd emotions.

However, risks remain: ASI has not reached the threshold, the market is fragmented, and many altcoins are just short-term fireworks. History also shows that altseason often appears when Bitcoin enters a stable phase.

In my opinion, the climax of altseason is likely to come in Q4 2025 or early 2026, following the familiar roadmap: Bitcoin → Ethereum → Major Altcoins → Mid-cap → Meme coins. Investors need to be patient and ready because when the real altcoin wave rises, it will wait for no one.
