Recent shifts in altcoin market cap rankings signal evolving investor sentiment and market dynamics. Rising altcoins like Sui surpassing Aptos in market cap reflect growing interest in scalability and niche use cases, such as gaming or DeFi. Posts on X note capital flowing from Bitcoin (dominance up to 60.25%) to altcoins, hinting at a potential altseason where mid- and low-cap coins could surge. Web data shows the altcoin market cap dropping 43.75% from its 2024 peak (400B to 225B), yet certain altcoins outperform amid bearish signals (e.g., RSI 40-45). This suggests a selective rally driven by fundamentals or hype, not a broad recovery. Volatility and FOMO may amplify these changes, but sustainability remains uncertain without wider adoption.
