Despite expectations, 2025 did not see the anticipated altcoin season, as Bitcoin's dominance and market conditions shifted focus away from altcoins. Analysts now suggest that 2026 could witness a significant altcoin rally, with prices nearing a crucial multi-year support level. The altcoin season index remains neutral, but a decline in Bitcoin dominance in November has sparked optimism. Investors are encouraged to monitor key indicators such as altcoin accumulation by major holders, the outperformance of leading altcoins, and shifts in liquidity driven by potential rate cuts and the conclusion of quantitative tightening. These factors could signal the onset of a new altcoin season.
