[Analysis: Bitcoin's Long-Term MACD Indicator Signals Bullish Trend, $71,147 as Key Level for Trend Confirmation] According to CoinDesk, Bitcoin's long-term MACD indicator has crossed above the zero line, signaling a bullish trend, suggesting that the recent rebound past $64,000 may continue. This indicator uses longer-period parameters to filter out short-term noise. During the decline from the historical high of $126,000, its downward signals accurately corresponded to major drops, while upward signals accurately aligned with rebounds. Analysts have identified three key resistance levels: the 50-day moving average around $65,434, the mid-June high of $67,292, and the 200-day moving average around $71,147. Breaking above the 200-day moving average is the critical signal for confirming a fully bullish trend. Additionally, in the Deribit options market, the $80,000 strike price has an open interest nominal value exceeding $1.21 billion, the highest among all strike prices.
