[Analysis: Bitcoin Options Sentiment Turns Bearish, Market Expectations for Breaking Below $80,000 Increase] Odaily Planet Daily News – As funds continue to flow out of spot Bitcoin ETFs, the Bitcoin options market is signaling a clear bearish sentiment, with the probability of BTC breaking below $80,000 increasing. In the derivatives market, the Bitcoin options delta skew indicator once rose to 17%, hitting a more than one-year high and significantly exceeding the typical neutral market level of no more than 6%, reflecting extreme risk-averse sentiment. Additionally, the total open interest in Bitcoin futures has dropped to $46 billion, down significantly from the $58 billion high three months ago, indicating that excessive leverage is gradually being cleared out. Overall, sentiment in the Bitcoin derivatives market remains cautious. Analysts believe that whether Bitcoin can regain a position above $87,000 may depend on whether market risk appetite recovers after macroeconomic uncertainties ease. (Cointelegraph)
