#美联储回购协议计划 There's an interesting saying — Bitcoin's market share has been staying high after bouncing off support levels, and that's why altcoins have been bleeding recently.

The key issue is this: as long as $BTC's dominance can't hold the downward trend, other coins will find it hard to have a chance. Every time Bitcoin pulls back, where does the market capital go? It flows back into BTC, not into picking up cheap altcoins. This creates a vicious cycle — the stronger BTC is, the more its dominance squeezes the survival space of altcoins.

So the current rhythm is: if you're betting on an altcoin rebound, first check whether BTC's market share is really showing signs of a downward trend. Otherwise, relying solely on positive news about a single project might not generate much of a ripple.
