The overall market fundamentals remain stable, but this does not mean a full-scale rally. The independent performance of BTC and ETH has already decoupled from the rise and fall of altcoins—you go your way, I go mine, each moving independently. For investors heavily invested in altcoins and deeply trapped, a market rebound does not equal self-rescue. When mainstream coins surge, altcoins often lag behind; when mainstream coins consolidate, altcoins continue to weaken. Don't think that bottoming out altcoins can turn around overnight; such situations are most likely to lead to self-deception in a bear market.
