The current market sentiment is very sensitive, somewhat like in July and August of the past year. A drop immediately triggers calls for a bear market, while a rise makes people think a bull market has arrived. When the market strengthens, short sellers are immediately squeezed; when it weakens, long positions are scared out. Even if the price of Bitcoin rises further, retail investors will not FOMO into buying BTC, because everyone feels that the price is too high to enter. Therefore, to trigger emotional resonance, it can only rely on altcoins to set the pace.
