If BTC pulls back to 78,000 points, consider entering with a light position in the short term for the following reasons:

1. Technical Support: This level may be a historically dense trading area or a Fibonacci retracement level, which presents a probability of a rebound;

2. Oversold Signal: If the RSI is below 30 and MACD shows a bottom divergence, it indicates a release of short-term selling pressure and an increase in rebound momentum;

3. Emotional Recovery: After panic selling, the market is prone to emotional recovery rebounds, providing arbitrage opportunities;

4. Incremental Strategy: Consider starting with a position of 5%-10%, and if it stabilizes with increased volume at the support level, add more to reduce one-time risk;

5. Clear Stop Loss: If it falls below the support by 3%-5% (e.g., 75,000 points), then stop loss to keep risk manageable.

It is necessary to combine with fundamentals (such as policies and capital flow) to confirm the trend and avoid heavy positions against the trend.
