After Bitcoin breaks through $100,000, the explosion time for altcoins depends on multiple factors such as market sentiment, capital rotation, and technical resonance. Based on the current market dynamics, altcoins may experience significant growth in the second half of 2025 (Q3, Q4), especially after Bitcoin stabilizes at $100,000 and enters a consolidation period, when capital may accelerate its shift towards high-potential altcoins. Market sentiment has entered the 'greed' range (Fear and Greed Index at 73 points), providing fertile ground for the explosion of altcoins. Historical data shows that when Bitcoin's dominance falls from a high (e.g., from 65% to 63.89%), and the altcoin quarterly index jumps from 23 to 36, it often indicates that capital begins to flow from Bitcoin to altcoins.
