After Bitcoin surpassed one hundred thousand dollars, the explosion time of altcoins depends on multiple factors such as market sentiment, capital rotation, and technical resonance. From the current market dynamics, altcoins may experience significant increases in the second half of 2025 (Q3, Q4), especially after Bitcoin stabilizes at 100,000 dollars and enters a consolidation period, capital may accelerate its shift towards high-potential altcoins. Market sentiment has entered the 'greed' range (Fear and Greed Index at 73 points), which provides fertile ground for the explosion of altcoins. Historical data shows that when Bitcoin's dominance declines from a high level (such as from 65% to 63.89%), and the altcoin quarterly index jumps from 23 to 36, it often indicates that capital is beginning to flow from Bitcoin to altcoins.
