According to Wintermute’s 2025 report on digital asset OTC markets, last year’s altcoin rallies were much briefer than traders anticipated, lasting only about 19–20 days on average. This marks a sharp decline from the roughly 60-day rallies seen in 2024. As market liquidity tightened, gains for many smaller tokens evaporated more quickly. Consequently, capital flowed back into major assets like Bitcoin and Ethereum, which offer deeper liquidity.
A key trigger was a significant deleveraging event on October 10, 2025, which prompted retail traders to reduce risk and exit smaller tokens. Open interest in altcoin futures contracts fell sharply, with some reports noting a decline of about 55% since October. Trading desks observed that lower liquidity made it difficult for rallies to sustain beyond a few weeks, turning what were once multi-month trends into short bursts.
Institutional flows and products like ETFs helped channel funds toward Bitcoin and Ethereum, narrowing the market’s focus. While narratives previously drove rallies across dozens of tokens, capital became increasingly concentrated in top-tier assets. Traders showed a preference for assets where large orders could be executed without drastically affecting prices.
Wintermute’s analysis highlights a shift in how momentum builds. Rallies became more tactical and less driven by broad, enduring narratives. In practice, this meant trends like memecoin surges and exchange-themed rallies burned out quickly. Traders described these moves as “hair-trigger” events—rapid upswings followed by equally swift retracements, with liquidity tightening and stop-losses being triggered earlier than in past cycles.
Market participants believe a sustained altcoin season would require several factors to align: renewed retail interest, clearer institutional support for smaller tokens, and calmer macroeconomic conditions. Without these, rallies are likely to remain short-lived. Execution desks noted that while tokens could surge quickly when large buyers emerged, maintaining momentum was difficult without broader market participation.
Looking ahead to 2026, a broader crypto rebound hinges on several factors: continued institutional interest, shifts in macroeconomic interest rates, and the return of retail investors to risk-on strategies. If these elements materialize, rallies could last longer than the 19–20 day average of 2025. Otherwise, traders expect the pattern of quick, sharp moves into major assets to persist.
