Bitcoin yesterday morning started a sideways correction from the 87,800 USD high, with the white trading session seeing a dip to around 86,100 USD before stabilizing and rebounding. In the evening, boosted by US stock market momentum, the price quickly surged past the previous consolidation range, reaching a high of around 90,300 USD. However, profit-taking at higher levels triggered a decline, with the low briefly dropping to 85,282 USD, then stabilizing and consolidating around 86,000 USD. From a technical perspective, the current 4-hour chart remains within a downward channel, with a short-term bearish trend. The 85,000 USD round number is a key support level; whether this support holds will directly determine the next trend direction—if support is maintained, a phase rebound may occur; if broken, further downside space could open.
