A buy order was executed partially or in full when the price bid could be matched against a sell order that was at or below the bid amount.  A sell order was executed partially or in full when the price asked could be matched against a buy order that was at or above the ask amount.  Orders that could not be matched immediately remain in the orderbook.
+
買い注文は、価格入札が入札額以下の売り注文と照合できる場合に、部分的にまたは完全に実行された。求められた価格が尋その金額以上である購入注文と照合できる場合、売り注文は部分的にまたは完全に実行された。直ちに対応できなかった注文は、注文書に残ります。
  
−
Unfunded orders did not appear in the order book, but were automatically inserted when a deposit was credited. For example, Mt. Gox allowed the entry of a "buy" order even if the account had insufficient funds.  If possible, Mt. Gox would execute a portion of the order if it could be partially funded.  If a deposit was later credited and the deposit resolves the insufficient funds status of an outstanding order, the order would be immediately activated, and if possible, executed.
+
未払いの注文は注文書には表示されませんでしたが、入金が記入された時に自動的に挿入されました。たとえば、Mt. Goxは、口座の資金が不足していても「買い」注文の入力を許可しました。可能であれば、Mt. Goxは、部分的に資金提供が可能な場合、注文の一部を実行します。預金が後にクレジット記入され、預金が未払いの注文の不十分な資金状況を解決する場合、注文は直ちに有効化され、可能であれば実行されます。

Mt. Gox charged a trading fee of up to 0.6% from each party of successful trades made through the market.  The fee appeared in the account history next to each trade.  The trading fee was discounted for larger customers based on volume, which was calculated as a sliding window over the last 720 hours (30 days).
+
富士山Goxは、市場を通じた成功した取引の各当事者から最大0.6％の取引手数料を請求した。料金は、各取引の横のアカウント履歴に表示されます。取引費用は、大量の顧客の場合、過去の720時間（30日間）にわたるスライドウィンドウとして計算された量に基づいて割り引かれました。
  
−
The fees were, by default, subtracted from the proceeds of each trade (e.g., a buy of 1.0 BTC will add to the account balance 0.994 BTC when the exchange fee is 0.6%).  An account setting would allow fees to be added to the purchase amount instead (e.g., buying 1.0 BTC at $5 will cost about $5.03 when the exchange fee is 0.6%).
+
手数料は、デフォルトで、各取引の収益から差し引かれた（例えば、交換手数料が0.6％の場合、1.0BTCの購入により0.994BTCの口座残高が追加される）。アカウント設定では、購入金額に料金を追加することができます（たとえば、$ 5で1.0 BTCを購入する場合は、交換手数料が0.6％の場合、約5.03ドルの費用がかかります）。

「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[1][2][3][4][5][6] Accounts with the equivalent of more than $8,750,000 were affected.[3] In order to prove that Mt.Gox still had control of the coins, the move of 424,242 bitcoins from "cold storage" to a Mt.Gox address was announced beforehand and executed in Block 132749.[7] It was later revealed that the coins may have never been in cold storage, as the proof-of-solvency transaction was broadcast through a remote Linux desktop and a single hot wallet.[8]

In October 2011, about two dozen transactions appeared in the block chain (Block 150951)[9] that sent a total of 2,609 BTC to invalid scripts. As they were impossible to satisfy/redeem, these Bitcoins were effectively destroyed.

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".

In March 2013, the new 0.8.0 version of Bitcoin Core temporarily forked off the main blockchain using differing rules on how transactions could be accepted. The Mt. Gox bitcoin exchange briefly halted bitcoin deposits. Bitcoin prices briefly dipped by 23% to $37 as the event occurred[10][11] before recovering to their previous level in the following hours, a price of approximately $48.[12]

Suspension of trading 2013

Mt. Gox suspended trading on 11 April 2013 until 12 April 2013 2 am UTC for a "market cooldown".[13] 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.[14]

Mt. Gox suspended withdrawals in US dollars on June 20, 2013.[15] The Mizuho Bank branch in Tokyo that handled Mt. Gox transactions pressured Mt. Gox from then on to close its account.[14] 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.[16][17][18]

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.[19]

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.[20] The companies had formed a partnership in February 2013 under which CoinLab handled all of Mt. Gox's North American services.[20] CoinLab's lawsuit contends that Mt. Gox failed to allow them to move existing U.S. and Canadian customers from Mt. Gox to CoinLab.[20]

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.[21] 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.[21][22] Between May and July more than $5 million were seized. [14] On 29 June 2013, Mt. Gox received its money services business (MSB) license from FinCEN.[22]

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.[23] 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.[24]
