A registrant on MtGox has at least two sub-accounts: one for bitcoins (BTC), and one for US dollars (USD or MTGUSD) or other national currency. Bitcoins are bought using funds from the trader's national currency account, and the proceeds from the sale of bitcoins are deposited into the same account. Trading must always involve bitcoins as trading between different national currencies is not offered.
Trades on Mt. Gox's execute from balances on deposit with the exchange which in turn makes trading on the market instantaneous, compared to some other Bitcoin markets where a subsequent settlement occurs manually between the trading partners. The disadvantage of this is that a third party must be trusted with keeping the money safe.
MtGox was originally started by Jed McCaleb in July 2010, and was sold to Tibanne Co. in Japan in March 2011. It is currently operated by Tibanne Co., managed by Mark Karpeles (MagicalTux).

Buying and selling
Buying and selling Bitcoins is simple. A buy order is executed partially or in full when the price bid can be matched against a sell order that is at or below the bid amount. A sell order is executed partially or in full when the price asked can be matched against a buy order that is at or above the ask amount. Orders that cannot be matched immediately remain in the orderbook.
Unfunded orders do not appear in the order book, but are automatically readded if a deposit is credited. For example, Mt. Gox allows the entry of a "buy" order even if the account has insufficient funds. If possible, Mt. Gox will execute a portion of the order if it can be partially funded. If a deposit is later credited and the deposit resolves the insufficient funds status of an outstanding order, the order will be immediately activated, and if possible, executed.
Mt. Gox charges a trading fee of up to 0.6% from each party of successful trades made through the market. The fee appears in the account history next to each trade. The trading fee is discounted for larger customers based on volume, which is calculated as a sliding window over the last 720 hours (30 days).
The fees are, 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 will 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%).
There are no fees incurred when transferring bitcoins to a Mt. Gox account.
The deposit address is presented along with a QR code that can be scanned with a mobile. This address does not change with each deposit request.
The Add Bitcoins function experiences issues with some browser ad-blocking utilities even though no advertisements are displayed on the website.
Bitcoins from another Mt. Gox user sent by Mt. Gox redeemable code may be deposited and will be available for trading immediately.
Dwolla is among the fastest and least expensive methods for adding funds to a Mt. Gox account. The transaction fee on Dwolla is merely $0.25. The process is automated and the funds become available for trading within an hour.
OKPay may be used for depositing funds to USD, EUR, GBP, CHF, and RUB.
In the U.S., cash may be deposited at any of thousands of banks in which BitInstant will use to transfer funds to your Mt. Gox account.
BitInstant will convert Liberty Reserve digital currency and will transfer those funds to your Mt. Gox account.
Funds in USD may be wired to the exchange's bank in Japan. Each wire is subject to a per-wire fee plus any intermediate fees.
An account can be configured with a wallet for each of the currencies that the exchange supports. When a wire is received in one of these currencies, that account will be credited.

AurumXChange USD, EUR and CAD
Funds may be wired to AurumXChange Company as USD, EUR or CAD (the latter two of which would then be exchanged into USD) for for purchase of a Mt. Gox USD redeemable code (voucher). Other digital currencies such as Liberty Reserve can be converted for transfer to Mt. Gox as well. The redeemable code provided is then used to load USD funds into an account with Mt. Gox.
Funds in EUR may be added using SEPA Direct Debit for free, with funds convert to USD at the current ECB rate at the time the funds are received.
Mt. Gox doesn't directly support an ACH-based (direct deposit) deposit method. Dwolla supports ACH-based fund transfers and those funds can then be deposited with Mt. Gox.
Funds may be sent as a GBP direct deposit free of charge.
Funds may be sent using direct deposit (BPay) for a AU$2.00 per-deposit fee. The funds will be converted to USD at the current rate.
MtGox imposes a $1,000 USD limit for withdrawals per 24 hours and a $10,000 USD limit for withdrawals per month with most non-verified accounts. Bitcoins withdrawn are counted toward this limit as well and the USD value is calculated at the market rate at the time of the attempted withdrawal. Customers that have been Verified have higher limits and customers that have Trusted status have limits even higher. Any account-to-account transfers made also count toward this limit as well.
Requests for higher withdrawal limits may be submitted by email
- For higher limits for withdrawal of USD funds, email: firstname.lastname@example.org
- For higher limits for withdrawal of BTC funds, email: email@example.com
See the AML section regarding verification levels for AML purposes.
Dwolla is among the fastest and least expensive methods for withdrawing USD funds from a Mt. Gox account. The transaction fee to do so is just $0.25. Dwolla withdrawals are processed every hour during business hours (Japan time) and every 12 hours on weekends.
Bitcoins may be withdrawn at no charge.
A green address option is available though this type of transaction could experience a delay if the exchange's wallet funding level for green address transactions is insufficient. The withdrawal form also offers an "open transaction" option which forces the transaction to go through the blockchain. If the recipient of a BTC withdrawal happens to also be from Mt. Gox's EWallet, then that transfer would occur instantly and the transaction would not be broadcast to the Bitcoin network. This "open transaction" option forces a withdrawal to be broadcast to the Bitcoin network.
Bitcoins to another Mt. Gox account may be sent by Mt. Gox redeemable code.
Redeemable Code (Currency)
Funds may be withdrawn by sending a Mt. Gox redeemable code (voucher) to another party.
The denominated of the code will be for the currency of the account's wallet that is active when the withdrawal request is inititiated (e.g., MTGUSD, MTGEUR, MTGAUD, MTGCAD, etc.)
Following are some of the services which accept a Mt. Gox redeemable code.
AurumXChange USD, EUR and CAD
Funds sent to AurumXChange Company can then be wired to a USD, EUR or CAD bank account or they can be converted to another digital currency, such as Liberty Reserve.
USD funds sent to to BitInstant can then be transferred further through their service.
There is currently no option for withdrawing funds through a direct deposit bank transaction. Funds withdrawn to Dwolla may then, in turn, be withdrawn with bank funds deposited as an ACH transaction.
You may withdraw any amount as a direct deposit to your bank. There is a 2% fee on these withdrawals. Contact the exchange by e-mail for this service.
A per-withdrawal fee is subtracted and the remaining amount is converted to AUD and sent through Technocash.
Transfers to Other Customers
Mt. Gox funds, either USD or BTC, may be sent to another Mt. Gox customer using a redeemable Mt. Gox code (voucher).
The preferred method for obtaining service is to place a request through the exchange's help desk. Another method is to send e-mail with the request.
Varying degrees of verification will allow for greater per-day and per-month total amounts to be withdrawn.

Online sellers can accept bitcoins for payment using the Mt. Gox's E-commerce Solution, which is an interface to the exchange's Merchant System API.
The exchange went online on July 18, 2010.
On October 10, 2010 the exchange switched from PayPal to Liberty Reserve as the main funding option as a result of this attack. Former PayPal customers still had the possibility to withdraw their USD using alternative methods.
On June 19, 2011 the service experienced a significant security breach. The incident caused a selloff down to BTC/USD of $0.01 due to fraudulent trading. The site was disabled and all trading following the point that fraudulent trading began was rolled back. Complicating this breach was the release of a list of the exchange's accounts including username, email address and a password hash, which forced the exchange to implement an account recovery method for customers to regain control of their accounts.
In July, 2011 it was observed that the exchange no longer allows new registrations to occur without having a valid e-mail address.
Announced on March 6, 2012 was the Merchant Solution and API
