On 19 June 2011, a security breach of the Mt. Gox bitcoin exchange caused the nominal price of a bitcoin to fraudulently drop to one cent on the Mt. Gox exchange, after a hacker allegedly used credentials from a Mt. Gox auditor's compromised computer illegally to fabricate a large number of bitcoins for himself. He used the exchange's software to sell them all nominally, creating a massive "[[Ask price|ask]]" order at any price. The price eventually corrected to its correct user-traded value.<ref>[https://support.mtgox.com/entries/20224998-huge-bitcoin-sell-off-due-to-a-compromised-account-rollback Huge Bitcoin sell off due to a compromised account - rollback]</ref><ref>{{cite press release | last=Karpeles | first=Mark | title=Clarification of Mt Gox Compromised Accounts and Major Bitcoin Sell-Off | date=30 June 2011 | url=https://mtgox.com/press_release_20110630.html | publisher=Tibanne Co.

On 22 February 2013, following an introduction of new anti-money laundering requirements by [[Dwolla]], some Dwolla accounts became temporarily restricted. As a result, transactions from Mt. Gox to those accounts were cancelled by Dwolla. The funds never made it back to Mt. Gox accounts. Mt. Gox help desk issued the following comment: "Please be advised that you are actually not allowed to cancel any withdrawals received from Mt. Gox as we have never had this case before and we are working with Dwolla to locate your returned funds." The funds were finally returned on May 3, more than 3 months later, with a note "Please be advised never to cancel any Dwolla withdrawals from us again".

2013年2月22日に、[Dwolla]による新たなマネーロンダリング防止要件の導入後、一部のDwollaアカウントは一時的に制限されました。その結果、Goxからそれらのアカウントへの取引はDwollaによってキャンセルされました。資金は決してそれをGoxのアカウントには戻さなかった。 Goxのヘルプデスクは次のようなコメントを出しました。「Goxからの引き出しをキャンセルすることは許可されません。私たちもこのような事例を今まで経験したことがないため、資金を見つけるためにDwollaと共同して努めております。資金は最終的に3ヶ月後の5月3日に返還されました。「Dwollaの引き出しをもう一度キャンセルしないように注意してください。

「Mount Gox」または単に「Gox」と呼ばれるGoxは、2010年の開始直後から2013年後半にかけての破産まで、最も広く使われていたビットコイン[為替交換]市場でした。引用エラー: <ref> タグに対応する </ref> タグが不足しています The value of a single bitcoin fell to a low of $55.59 after the resumption of trading before stabilizing above $100. Around mid May 2013, Mt. Gox traded 150,000 bitcoins per day per Bitcoin Charts.[1]

Mt. Gox suspended withdrawals in US dollars on June 20, 2013.[2] The Mizuho Bank branch in Tokyo that handled Mt. Gox transactions pressured Mt. Gox from then on to close its account.[1] On July 4, 2013, Mt. Gox announced that it had "fully resumed" withdrawals, but as of September 5, 2013, few US dollar withdrawals had been successfully completed.[3][4][5]

On August 5, 2013, Mt. Gox announced that they incurred "significant losses" due to crediting deposits which had not fully cleared and that new deposits would no longer be credited until the funds transfer was fully completed.[6]

CoinLab lawsuit and Homeland Security seizure of US funds

On 2 May 2013 CoinLab filed a $75 million lawsuit against Mt. Gox alleging a breach of contract.[7] The companies had formed a partnership in February 2013 under which CoinLab handled all of Mt. Gox's North American services.[7] CoinLab's lawsuit contends that Mt. Gox failed to allow them to move existing U.S. and Canadian customers from Mt. Gox to CoinLab.[7]

On 15 May 2013 the US Department of Homeland Security (DHS) issued a warrant to seize money from Mt. Gox's US subsidiary's account with payment processor Dwolla.[8] The warrant suggests the US Immigration and Customs Enforcement, an investigative branch of the DHS, felt that the subsidiary, which was not licensed by the US Financial Crimes Enforcement Network (FinCEN), was operating as an unregistered money transmitter in the US.[8][9] Between May and July more than $5 million were seized. [1] On 29 June 2013, Mt. Gox received its money services business (MSB) license from FinCEN.[9]

Withdrawals delayed or refused

Wired Magazine reported in November 2013 that customers were experiencing delays of weeks to months in withdrawing funds from their accounts.[10] The article said that the company had “effectively been frozen out of the U.S. banking system because of its regulatory problems”. Customer complaints about long delays were mounting as of February 2014, with more than 3300 posts in a thread about the topic on the BitcoinTalk online forum.[11]
