[Matrixport Indicates Altcoin Rebound Did Not Sustain and Bitcoin's Short-Term Momentum Weakens] Matrixport analysis points out that although the decline in Bitcoin's market dominance once led to a temporary rebound in altcoins, the rebound failed to sustain as the overall crypto market capitalization weakened. Over the past year, altcoins have generally underperformed, with market preference still concentrated on Bitcoin. Currently, Bitcoin's short-term momentum is weakening, and risk appetite recovery remains limited, suggesting that altcoin trends may primarily feature structural divergence. At this stage, trading should focus on top-tier assets with better liquidity and trading depth, while strengthening risk control and position management. The market has gradually shifted from a 'long-term holding + dollar-cost averaging' approach to an environment emphasizing timing entry and active trading.
