After Bitcoin breaks $100,000, the explosion of altcoins depends on multiple factors such as market sentiment, capital rotation, and technical resonance. From the current market dynamics, altcoins may see significant increases in the second half of 2025 (Q3, Q4), especially after Bitcoin stabilizes at $100,000 and enters a consolidation phase, where capital may accelerate its shift towards high-potential altcoins. Market sentiment has entered the "Greed" zone (Fear and Greed Index at 73), 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 signals that capital begins to flow from Bitcoin to altcoins.
