比特幣銀行服務Flexcoin在週日的一次攻擊中丟失了896枚比特幣，價值36.5萬英鎊(約合61萬美元)。該公司承認，沒有足夠資金來應對這一損失，因此將被迫關閉。
Flexcoin已關閉網站，並於週二早間釋出宣告，解釋了損失情況。宣告稱：“2014年3月2日，Flexcoin遭遇攻擊，而熱錢包(hot wallet)中的所有比特幣被盜一空。由於Flexcoin沒有資源和資產去應對這一損失，我們將立即關門。”
不過，該公司並非全部資產被盜。遵循比特幣金融服務的最佳行為規範，Flexcoin對一些比特幣進行了“冷儲存”，即儲存在未連線網際網路的裝置中。這些比特幣仍是安全的。不過，只有要求將比特幣進行冷儲存的使用者能從中受益，而此前冷儲存需要0.5%的手續費。
宣告稱：“Flexcoin將與冷儲存比特幣的使用者聯絡，並要求他們驗證身份。一旦身份確認，冷儲存的比特幣將以免手續費的方式轉移。冷儲存的比特幣被離線保管，沒有受到攻擊的影響。Flexcoin將與司法部門合作，追蹤攻擊來源。”
Flexcoin試圖在比特幣體系內引入傳統銀行系統。該服務允許兩名Flexcoin使用者之間免費轉移比特幣，也支援使用者在更廣泛的比特幣社群內使用比特幣。
僅僅6天前，Flexcoin曾發表宣告稱，比特幣交易所Mt.Gox的關閉未對其產生影響，該公司並未丟失任何比特幣。Flexcoin的關閉再次表明，比特幣社群存在明顯的資訊保安問題。(維金)
——【Flexcoin 關閉宣告】——
Flexcoin is shutting down.
On March 2nd 2014 Flexcoin was attacked and robbed of all coins in the hot wallet. The attacker made off with 896 BTC, dividing them into these two addresses:
1NDkevapt4SWYFEmquCDBSf7DLMTNVggdu
1QFcC5JitGwpFKqRDd9QNH3eGN56dCNgy6
As Flexcoin does not have the resources, assets, or otherwise to come back from this loss, we are closing our doors immediately.
Users who put their coins into cold storage will be contacted by Flexcoin and asked to verify their identity. Once identified, cold storage coins will be transferred out free of charge. Cold storage coins were held offline and not within reach of the attacker. All other users will be directed to Flexcoin’s “Terms of service” located at “Flexcoin.com/118.html” a document which was agreed on, upon signing up with Flexcoin.
Flexcoin will attempt to work with law enforcement to trace the source of the hack.
Updates will be posted on twitter as soon as they become available.
