According to Altcoin Daily, traders are debating whether an 'altcoin season' is setting up after the Dec 11, 2025 post raised the question on X, putting focus back on rotation timing; source: Altcoin Daily on X.

According to @rovercrc, the TOTAL3 market cap, which tracks the combined value of all cryptocurrencies excluding BTC and ETH, has just flashed a Golden Cross signal. In the previous two instances when this technical indicator appeared, altcoins experienced substantial price surges. Traders are closely monitoring this development as it historically precedes significant altcoin rallies, suggesting that another major pump in the altcoin market may be imminent if the pattern holds. This signal is prompting increased trading activity and renewed bullish sentiment among altcoin investors, as cited by the source.
