比特幣在關鍵支撐位（成本價格防線）只有在大玩家和機構重新進入市場並將其穩定到某些水平時才能進行防禦。

According to BlockBeats, recent data from CryptoOnchain indicates that Bitcoin is currently testing a critical support level, known as the 'cost price defense line' of new major investors. This line represents the average holding cost of significant new market entrants. Historically, large investors have often defended this cost line to avoid losses, with this position serving as a strong demand bottom multiple times since August, including twice recently. The central question facing the market now is whether these major investors will intervene to support the price again. The upcoming market movements at this key level are crucial.
