BTC has fallen from the intraday high of $67,229.9 to $65,508.1, a daily decline of 2.43%. It broke below the key support of the daily EMA5, short-term bullish structure is damaged, the 4-hour chart confirms a MACD death cross, indicating the release of band-wide bearish momentum, and the 1-hour chart has entered a serious oversold zone. Overall, this is a technical correction after a rebound, and the long-term core logic of the halving expectation remains intact. There is strong support around $64,200 below, and a technical rebound could be triggered at any time after overselling.
