Several prominent cryptocurrency narratives failed to materialize in 2025, impacting market dynamics. The anticipated Bitcoin super cycle did not occur, with prices failing to reach the projected $150,000 mark by Q4. Additionally, the excitement surrounding AI agents waned as development lagged behind expectations. Meme coins also lost momentum following multiple rug pulls and a market pivot towards projects with tangible utility. Analysts suggest that some altcoins could regain interest in 2026 as the market adjusts.
