The Bitcoin within-day range is fluctuating with little volatility. Early session dipped to support at 78,200 and stabilized with a rebound, surged to 80,500 but faced resistance and consolidated; in the evening, after a second test of support, it rebounded again to test the resistance, forming a standard oscillation structure!

From the current market structure, Bitcoin has confirmed key support, and the long-term bullish trend remains intact, with the core upward pattern unchanged. After the battle between bulls and bears, the oscillation center has shifted upward overall, and bulls still dominate the market.
The focus for the future is whether 80,500 can be effectively broken and stabilized; this level is the critical watershed for whether the short-term bulls can open a new round of upward space. The trading strategy remains mainly low-positioned long positions.
Bitcoin retraced near 79,300-78,500 to buy, with targets at 71,500-73,000; a breakout could target 74,500.
The altcoin retraced near 2,330-2,300 to buy, with targets at 2,430-2,550.
