[Analysis: Bitcoin Shows 'Bullish' Signal, $90,000 Becomes Key Price Level] According to Cointelegraph's analysis, Bitcoin miner indicators and market sentiment indices have recently issued simultaneous 'buy' signals, bringing positive signs to the market. The hash ribbons indicator (which measures the 30-day and 60-day moving averages of hash rate) has flashed a 'buy' signal, suggesting that the miner capitulation phase may be over. Historically, this signal often coincides with significant price discounts and long-term buying opportunities. The last time this signal appeared was in July 2025, after which Bitcoin rose 25% to reach an all-time high. At the same time, the 30-day moving average of the Crypto Fear and Greed Index has crossed above the 90-day moving average for the first time since May 2025, indicating that market sentiment is shifting from prolonged fear to optimism. Analysts emphasize that $90,000 is a critical psychological and technical support level that Bitcoin must hold. This level coincides with the 200-period moving average on the 4-hour chart and the lower boundary of the bearish flag pattern on the weekly chart. If this level holds, buyers will remain in control, and a rebound is expected. However, if the weekly closing price falls below this level, Bitcoin may further test the $80,000 to $85,000 range, or even challenge the April 2025 low of $74,500 and the 200-week moving average at $68,000.
