3 月 6 日，在比特幣短暫突破 72,000 美元阻力位後，價格開始回落至 70,000 美元區域附近。地緣政治局勢急速升溫成為當日最主要的宏觀壓力來源：川普公開要求主導伊朗下一任最高領袖的選任，伊朗外長明確表示準備迎戰美軍地面入侵，美國國防部長 Pete Hegseth 宣告對德黑蘭的火力打擊「即將大幅增加」。
地緣政治升溫：美伊衝突三重壓力同步爆發
川普週四接受採訪時表示，他需要親自介入伊朗最高領袖的繼任者選擇，稱已故最高領袖哈梅內伊的兒子穆傑塔巴·哈梅內伊是「無足輕重的人」，並援引其在委內瑞拉的干預模式：「我必須像對待委內瑞拉那樣，直接參與任命過程。」他補充，任何繼續推行哈梅內伊政策的新領導人都不可接受，否則將迫使美國「在五年內重新開戰」。
伊朗外長阿拉格齊隨即在採訪中強硬回應，明確表示既不要求停火，也不打算與美國展開任何談判。「不，我們正等著他們來。那對他們來說將是一場大災難，」他以挑釁的語氣補充道。
在軍事層面，國防部長 Pete Hegseth 宣告，美軍對伊朗的行動將進一步升級，包括部署更多戰鬥機中隊、提高轟炸機出動頻率，以及對德黑蘭的「顯著增加」打擊力度，並稱美軍正獲得更多海外基地支援。
技術面：72,000 是當前多空分水嶺
（來源：Trading View）
比特幣今日下跌的技術觸發點清晰可辨：比特幣在過去數週突破了長期阻礙多次上漲行情的 72,000 美元阻力位，但突破後未能維持，價格在地緣政治壓力下開始回落至 70,000 美元附近。
當前關鍵技術位一覽
核心支撐：72,000 美元——若能成功守住並轉化為支撐位，看漲格局得以維持
上行目標：80,000 美元 → 84,000 美元 → 若動能持續可延伸至 90,000 美元
下行風險：跌破 72,000 美元將壓力迅速移轉至 64,000 美元支撐區；若 64,000 美元失守，下一個關鍵防線在 60,000 美元
市場情緒：樂觀情緒升溫但分歧仍在
（來源：Polymarket）
值得注意的是，儘管比特幣今日下跌，整體市場情緒在過去數週已悄然轉向。預測市場平台 Polymarket 的數據顯示，交易者目前傾向於比特幣在 3 月達到 80,000 美元，隨後可能回落至 55,000 美元，部分分析師仍視後者為熊市的最終底部區間。
部分分析師認為最糟糕的低迷時期已經過去，市場動能正在改善；另一派則堅持認為當前反彈僅是動盪市場中的緩解性行情，無法確認趨勢反轉。當前比特幣今日下跌至 70,000 美元附近，正是這場多空分歧的直接體現，市場需要在此區域形成明確方向。
常見問題
比特幣今日下跌的主要原因是什麼？
今日比特幣下跌主要由兩大因素驅動：一是地緣政治風險急速升溫，美伊衝突在川普強硬聲明、伊朗拒絕停火及美軍宣告升級打擊三重疊加下引發避險情緒；二是技術面壓力，比特幣突破 72,000 美元後未能穩固支撐，回落至 70,000 美元附近觸發短線止損賣壓。
72,000 美元對比特幣走勢的意義是什麼？
72,000 美元是過去數週多次阻擋比特幣上行的關鍵阻力位，此次突破具有短期技術意義。若能守住該位置並將其轉化為支撐，則上方看向 80,000 至 84,000 美元；若突破失敗，則快速下探 64,000 美元的可能性上升。
伊朗局勢如何影響比特幣價格？
伊朗衝突升溫造成全球避險情緒上升，投資者傾向撤離比特幣等風險資產，轉向黃金等傳統避險標的。地緣政治事件通常只對比特幣產生短期波動影響，但若衝突進一步升級至更廣泛的地區戰爭，對金融市場的衝擊將更為持久。

SHIB Faces Rising Sell Pressure After 400B Token Inflows
Shiba Inu faces selling pressure as exchange reserves climb to ~81.5T SHIB and net inflows exceed 400B SHIB, with price trapped under resistance amid low volatility and muted market participation.
Abstract: This analysis notes SHIB's current market dynamics, highlighting exchange reserves near 81.5 trillion SHIB and net inflows over 400 billion SHIB, signaling rising distribution as holders prepare to sell. Prices remain below key resistance with low volatility and subdued volume, pointing to weak short-term momentum. The combination of larger inflows and outflows indicates strategic repositioning rather than accumulation, while broader market constraints limit upside. Overall, the outlook remains cautious with downside risk in the near term.
