**Current Status**: BTC has lost momentum after reaching new highs, facing profit-taking pressure, with all technical indicators turning bearish.**Short-term trend is downward**. The market is testing the support strength of the uptrend.

**Key Points to Watch**:
1. Closely monitor price performance in the **66,000 - 69,000 USD** support zone. If the price stabilizes with decreasing volume and bounces in this zone, the uptrend is expected to continue.
2. Observe whether the MACD histogram can narrow or turn positive, and whether RSI can rebound from the oversold zone above 50. These are signals of weakening downside momentum.
3. If volume increases and breaks below the **66,000 USD** key support, beware of trend reversal risk. The next target may be 64,000 or even lower.

* **Key Support Levels**:
1. **68,000 - 69,000 USD zone**: This is a platform area where multiple oscillations occurred in early and mid-March, and also where the recent EMA slow line is located. If it bounces, this level will convert to strong resistance.
2. **66,000 - 67,000 USD zone**: Important low point area from March 2 and March 9, also the neckline of the previous breakthrough, a critical support that must be held.
3. **64,000 USD (strong support)**: The launch platform for the rise at the end of February. If broken, the medium-term uptrend may be destroyed, and the market will enter a larger-scale correction.

* **Key Resistance Levels**:
1. **71,000 - 72,000 USD zone**: Current convergence area of EMA fast and slow lines, also the recent rebound high zone. Reclaiming this zone is the first signal of stabilization.
2. **73,500 - 74,000 USD zone**: Previous high area and the starting point of this decline, a key level for determining whether the trend can recover strength.
3. **76,000 USD (historical high resistance)**: The highest point of this rise, the ultimate target resistance for the future.
