According to market analysis, the altcoin season may start in Q3 (June-July) of 2025. The core triggering conditions include: Bitcoin dominance (BTC.D) falling below 58%, the market cap share of stablecoins continuing to decline, and the ETH/BTC exchange rate breaking the three-year downtrend line. Currently, BTC is nearing an all-time high, and market sentiment remains in a buildup phase before extreme greed, with retail participation being low, and funds flowing from Bitcoin to the altcoin sector. Historical trends show that the altcoin season often erupts 15-30 days after Bitcoin peaks, accompanied by the rise of the ETH ecosystem (such as the Pectra upgrade promoting improved interactive experience) and favorable policies (such as increased support for cryptocurrencies in the U.S.). Caution is advised regarding short-term market fluctuations, and it is recommended to focus on low market cap projects with solid fundamentals and to use a phased investment strategy.
