3 Signals Suggest Altcoin Season Could Begin In 2026

The fourth quarter of 2025 proved to be a challenging period for crypto markets, with most major assets ending the year in negative territory.

Bullish Divergences Signal Potential Altcoin Reversal

The first key signal is the formation of bullish divergences on weekly charts across several altcoins. This occurs when price hits lower lows but indicators, like the Relative Strength Index (RSI), form higher lows, suggesting weakening bearish momentum and increasing the probability of a trend reversal.

Cryptocurrency analyst Michaël van de Poppe pointed out this development, citing Optimism, Arbitrum, Near, and Avalanche as examples. According to him,

In a separate post, Bitcoinsensus drew attention to Bitcoin Dominance’s recent performance as a possible early indicator of an approaching altcoin season.

With bullish technical signals emerging alongside persistent doubt, the coming months will determine whether these patterns translate into sustained price momentum or remain signals without any follow-through.
