要點：
* 比特幣的價格仍然波動，交易範圍在86,000到90,000美元之間，而其與黃金的比率降至2024年1月以來的最低點。
* 幾個主要代幣的資金利率已轉為負值，顯示出期貨市場中空頭頭寸的積累。
* Yearn Finance的YFI代幣在遭遇30萬美元的舊智能合約漏洞後下跌近6%，這是本月內的第二次攻擊。
比特幣的表現相對於黃金持續不佳，與黃金的比率已降至20.18，這是自2024年1月1日以來的最低水平。根據TradingView的數據，這一持續的下降顯示出投資者仍然偏好黃金作為避險資產，特別是在一些人認為先進國家存在財政不當的情況下，以及市場對美聯儲降息的討論。
故事繼續
如果週四美國的通脹數據低於預期，則這一比率可能會改善，這可能會增加市場對降息的預期，並促進風險資產的投資。
衍生品市場定位
———————–
* 比特幣30天隱含波動率的下行趨勢在約50%附近停滯，但目前沒有重新上升的跡象，這意味著交易者目前不預期波動性會回升。
* MOVE指數，即美國國債的波動性指標，已降至62.73，為自十月以來的最低水平。國債市場波動性的下降通常對風險資產有利。
* 在主要代幣中，SOL、TRX和DOGE在期貨市場的未平倉合約（OI）有所增加。
* BNB、XRP、SOL、TRX和DOGE的資金利率已轉為負值。DOGE和TRX的未平倉合約增加及負利率的組合顯示出空頭頭寸的積累。
* 在Deribit，風險反轉持續顯示出對BTC和ETH看跌期權的偏好，顯示出持續的下行風險。
* 區塊流動性顯示出比特幣的買權日曆價差和跨式交易，以及以太坊的賣權價差和跨式交易。
代幣動態
———-
* Yearn Finance，作為DeFi中最早和最知名的收益聚合器之一，本週遭遇了另一個漏洞，攻擊者從一個舊的智能合約中竊取了約30萬美元。
* 這一漏洞與iEarn相關，iEarn是該協議的早期版本，距今已有近六年。安全公司PeckShield警告了這一漏洞，指出攻擊者將被竊取的資金兌換成了103個以太坊，價值約29萬美元。
* Yearn隨後迅速做出回應，澄清此次攻擊並未影響當前的金庫或合約。“問題僅限於iEarn，並不影響當前的Yearn合約或金庫，”團隊在X上發文表示。
* 這是Yearn在過去一個月內遭遇的第二次攻擊。12月初，攻擊者從另一個漏洞中竊取了約900萬美元。
* Yearn的YFI代幣在此次攻擊後下跌近6%，表現不如整個市場。根據數據顯示，自首次攻擊以來，該收益聚合器的總鎖倉價值下降了超過5000萬美元，降至5.6億美元。
在當前的加密市場中，比特幣的表現仍然受到廣泛關注，尤其是在其與黃金的比率持續下滑的情況下。這不僅反映了投資者對於黃金的偏好，也顯示出對於比特幣未來表現的擔憂。隨著市場對通脹數據的敏感性增加，投資者可能會重新評估他們的風險承擔能力，這將對比特幣及其他加密資產的價值產生影響。
在這樣的市場環境中，Yearn Finance的持續安全問題也引發了對DeFi平台安全性的擔憂。隨著越來越多的資金流入這些平台，如何保護用戶資產將成為未來發展的關鍵議題。
