Current Status: BTC has lost momentum after reaching a new high and is being pressured by profit-taking. Technical indicators have turned bearish across the board, with **short-term trend pointing downward**. The market is testing the support strength of the upward trend.

Key Points to Monitor:
1. Pay close attention to the price behavior within the **$66,000 - $69,000 support zone**. If the price can halt its decline with reduced volume and rebound in this area, the upward trend may continue.
2. Observe whether the MACD histogram can narrow or turn positive, and whether the RSI can recover from oversold levels back above 50—these are signals indicating weakening downward momentum.
3. If the price breaks below the **$66,000 key support level on high volume**, be alert to the risk of trend reversal. The next target could be $64,000 or even lower.

Key Support Levels:
1. **$68,000 - $69,000 zone**: This area has served as a consolidation platform multiple times in early and mid-March and is where the EMA slow line currently resides. A rebound from here would turn this level into a strong resistance.
2. **$66,000 - $67,000 zone**: Important low points from March 2 and March 9, also the previous breakout neckline, representing a critical support that must hold.
3. **$64,000 (strong support)**: The launchpad for the uptrend starting in late February. If broken, the medium-term upward trend could be invalidated, and the market may enter a larger correction.

Key Resistance Levels:
1. **$71,000 - $72,000 zone**: The current convergence area of the EMA fast and slow lines, also the recent rebound high point. Reclaiming this zone is the first sign of stabilization.
2. **$73,500 - $74,000 zone**: The previous high area and the starting point of this decline. This is a crucial level to determine whether the trend can regain strength.
3. **$76,000 (historical high resistance)**: The highest point of this rally and the ultimate resistance target moving forward.
