Short-term Bitcoin will fluctuate weakly around $65,000-$69,000, with heavy selling pressure above and limited room for a rebound. $66,000 is a key support level; if broken, it may drop to the $62,000 range. Institutions remain long-term bullish, believing that the current level is near the bottom, and ETF funds continue to lay the groundwork for a positive outlook. April is unlikely to see a big rally, mainly forming a bottoming process; close attention should be paid to USD liquidity and geopolitical news, with strict risk control on high leverage and cautious chasing of gains.
