There may be many reasons for the recent turnaround in the cryptocurrency market from rising to falling. Here are some key factors:

1. **Traditional market impact**: Some analysts have pointed out that investors have reduced their exposure to Bitcoin due to concerns about the impact of traditional markets, which may be a reason for the market correction.

2. **Macroeconomic concerns**: Although demand for Bitcoin derivatives as a hedging tool remains stable, people are worried that many economies may lose momentum or that confidence in the ability of governments to refinance debt is waning, which may have an impact on market sentiment.

3. **Bitcoin derivatives market stability**: Despite market volatility, indicators of Bitcoin derivatives remain very stable, indicating that the market does not have strong expectations for further declines.

4. **Bitcoin correlation with the stock market**: The 40-day correlation over the past month shows that the correlation between Bitcoin and the S&P 500 index has remained above 80%, indicating that the movements of the two asset classes are closely related.

5. **Market sentiment and technical indicators**: Despite potential selling pressure, market sentiment remains positive. Technical indicators show that the relative strength index (RSI) is 68, indicating that the upward momentum continues. The on-balance volume (OBV) data also showed strong buying activity, suggesting that further gains may be in the offing.
