There are several possibilities for BTC's movement in the next few days:

1. **Continue to oscillate**:

- **Current state**: BTC seems to be forming a converging triangle, which usually indicates an upcoming increase in volatility, but the direction is unclear. The market may continue to oscillate between 57,700 and 60,000, testing support and resistance levels.

2. **Test support downward**:

- **Support level test**: The four-hour chart shows that support in the 56,700 area may be tested downward. If this support level holds, it may trigger a rebound; if it fails, it may further look for the next support level.

3. **Rebound or continue to fall after a false breakout**:

- **False breakout**: After a false breakout, the market may try to test the upper resistance or lower support again. The movement after a false breakout is usually more drastic because it triggers stop-loss orders and the opening of new positions.

4. **Market sentiment and operation strategy**:

- **Wait and see**: Due to the mixed market signals at present, it is not recommended to enter the market in a big way in the short term. It is suitable to wait and see and wait for a clearer trend to emerge. Short-term traders can take advantage of these fluctuations, but they need to set stop losses and targets.

- **Long-term investment**: For long-term investors, now may not be the best time to enter the market unless there is a clear bottom signal or breakout signal.

5. **Technical indicators hint**:

- **Indicators such as EMA20**: Testing key technical indicators such as EMA20 moving averages may give clues to the market's next direction. If these moving averages begin to provide support or resistance, they can be used as a reference to judge future trends.

**Summary**:

- **In the next few days**, BTC may move cautiously and continue to find direction in the current range. Investors should pay close attention to the performance of the two key price levels of 56,700 and 60,000. Breaking through or effectively falling below these price levels may determine the direction of BTC's trend in the short term.

- **Recommendations**: Stay vigilant, set up take-profit and stop-loss, and be prepared to deal with sudden market conditions, because at the end of the triangle convergence, the market may quickly choose a direction.
