After Bitcoin broke 100,000 USD, the explosion time for altcoins depends on multiple factors such as market sentiment, capital rotation, and technical resonance. From the current market dynamics, altcoins may experience significant growth in the second half of 2025 (Q3, Q4), especially after Bitcoin stabilizes at 100,000 USD and enters a consolidation phase, where capital may accelerate its shift toward high-potential altcoins. Market sentiment has entered the 'greed' zone (Fear and Greed Index at 73 points), which provides a fertile ground for the explosion of altcoins. Historical data shows that when Bitcoin's dominance falls from a high (such as 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.
