位於日本的比特幣交易平臺MtGox昨天突然暫停交易和關閉網站，引發了大量傳言和譴責。其中一條傳言稱MtGox過去幾年被悄悄偷走了74.4萬比特幣。六大比特幣服務商為此聯合發表宣告，譴責Mt Gox“悲劇性地背棄了人們的信任”，承諾將恢復人們對比特幣的信心。
Blockchain.info的CEO Nicolas Cary說，“幾周以來，Mt Gox的傳聞一直在緩慢地趨於明朗。這一最新動態看來是他們動盪歷史上的最後一個悲慘章節。”
喬治城大學經濟學教授Jim Angel表示，比特幣就好像電子書，其好壞狀況有賴於支援其使用的基礎設施。“鑑於比特幣的基礎設施完全沒有監管、技術也是新興的，出現眼下這種問題應該在意料之中。”
MtGox已經在網站首頁發表簡短宣告，聲稱關閉交易是為了保護網站和使用者，除此之外沒有做出進一步解釋。
《華爾街日報》援引知情人士的訊息報導，MtGox已經收到紐約聯邦檢察機構發出的一張傳票。路透社報導稱，日本官員週三表示他們正著手對MtGox的突然關閉展開調查。內閣官房長官菅義偉說，相關金融監管機構、警方、財務省等正在收集資訊。MtGox CEO Mark Karpeles在一封電子郵件中表示，因為牽涉到其它方他目前不能透露太多資訊。

下面是 MtGox 官網的兩則宣告
February 26th 2014
Dear MtGox Customers,
As there is a lot of speculation regarding MtGox and its future, I would like to use this opportunity to reassure everyone that I am still in Japan, and working very hard with the support of different parties to find a solution to our recent issues.
Furthermore I would like to kindly ask that people refrain from asking questions to our staff: they have been instructed not to give any response or information. Please visit this page for further announcements and updates.
Sincerely,
Mark Karpeles
