Site Relaunch August 07, 2016

We are beginning the process of bringing the platform online in a controlled and secure way. Currently the site is available on a read-only basis as we continue to work towards enabling full functionality. This means that users will be able to log into their accounts but trading, depositing, and withdrawing will remain disabled at this time.

Please be aware of the following changes required by the ongoing platform recovery:

  • Users will be required to reset their password.
  • Users will be required to reset their 2FA, if applicable.
  • Clef has been disabled for all accounts. We have reset our security keys with Clef, requiring users to re-enroll.
  • All API keys have been revoked. The creation of new API keys will be re-enabled within the next 48 hours.

Please take this time to log in and review your account and balances, taking note of the adjustments caused by the closing of open margin positions and the application of the Extraordinary Loss Adjustment. The loss adjustment is represented by your balance in “BFX” tokens which are priced at 1.00 USD until we are able to allow trading of that token, likely within the next week. The trading of BFX tokens may be restricted for US customers.

Full platform functionality will come online in progressive steps in the coming days. Withdrawing, depositing and exchange trading will come online first, with margin trading (for non-US customers) to resume sometime after that. Further announcements will be made when the schedule for turning on those features is finalized. Once again, we thank you for your patience.

Security Breach - Update 3 August 06, 2016

Following the theft on August 2nd, the Bitfinex team has been working tirelessly towards bringing the platform back online in a secure and controlled manner. We have finalized the accounting of losses incurred and are currently coordinating strategic plans for compensating customers.

We intend to come online within 24-48 hours with limited platform functionality. Additional announcements will be made as we progressively enable more platform features and return to full operations. We appreciate that our customers and the public want this handled quickly, but it needs to be done a way in which all assets are secure and immune from vulnerabilities. Every resource is being leveraged to make that happen in a safe and optimal way.

As disclosed in earlier announcements, all withdrawals, open orders, and open funding offers have been canceled and all financed positions have been settled. Exact settlement prices were published on August 3rd.

After much thought, analysis, and consultation, we have arrived at the conclusion that losses must be generalized across all accounts and assets. This is the closest approximation to what would happen in a liquidation context. Upon logging into the platform, customers will see that they have experienced a generalized loss percentage of 36.067%. In a later announcement we will explain in full detail the methodology used to compute these losses.

We are actively discussing various strategic options with numerous potential investors as part of our strategy to fully compensate our customers. Such discussions, however, are in early stages and will likely take time to play out. In the meantime, In place of the loss in each wallet, we are crediting a token labeled BFX to record each customer’s discrete losses. Tokens will be distributed without release or waiver. The BFX tokens will remain outstanding until redeemed in full by Bitfinex or possibly exchanged—upon the creditor’s request and Bitfinex’s acceptance—for shares of iFinex Inc. We are still sorting out many details on this; we will post further updates in the coming days.

Thank you for your continued patience and for the many generous offers of support that we have received over the last several days. Notwithstanding this attack, we continue to believe in the possibilities associated with bitcoin. We will continue to update our customers and the public as and when we can.

Security Breach - Update 2 August 05, 2016

We have received reports that phishing emails are being circulated from an address made to appear to be from Bitfinex. The email is in fact sent from (notice the additional "i" in the domain name).

This is not a message sent out by Bitfinex and we advise anyone that has received this email or any similar email to delete it immediately. It appears the attachment on this email contains a virus. If you have opened this email's attachment, please do a system virus scan and take other necessary precautions to preserve your security and privacy.

If there is ever a doubt about the validity of a Bitfinex email or communication please send an email to [email protected] to inquire and we will be happy to confirm or deny the validity of the communication.

The malicious email begins like this:

We apologize to you for our inconveniences appeared in result of security incident. We intensively work with the law enforcement agencies to find out guilty people to make answer.


Again, this email is not from Bitfinex. It is an impostor sending phishing emails with an attachment containing a virus.

Security Breach - Update 1 August 03, 2016

We are currently in an ongoing process of restoring limited functionality in a secure environment, with full functionality coming afterwards in progressive stages. The first step is bringing the site online and allowing users to login and view the state of their accounts. Note that initially trading, deposits, withdrawals, and other core site functionality will be disabled.

To accommodate the relaunch, all withdrawals, open orders, and open funding offers will be canceled. Furthermore, in order to compute losses for relevant parties, settlement of all financed positions will occur in all accounts. Margin positions for all pairs will be settled and closed using the following prices, representing the midpoint of the bid and ask on August 2, 2016 at 18:00:00 UTC:

BTCUSD: 604.06000000
ETHUSD: 10.19050000
ETHBTC: 0.01689900
ETCUSD: 2.83700000
ETCBTC: 0.00471495
LTCUSD: 3.75180000
LTCBTC: 0.00621295

Further announcements about the next steps of the relaunch will be posted as progress is made. All significant changes to feature availability will be announced in advance. We will strive to keep you as informed as we can.

Security Breach August 02, 2016

Today we discovered a security breach that requires us to halt all trading on Bitfinex, as well as halt all digital token deposits to and withdrawals from Bitfinex.

We are investigating the breach to determine what happened, but we know that some of our users have had their bitcoins stolen. We are undertaking a review to determine which users have been affected by the breach. While we conduct this initial investigation and secure our environment, will be taken down and the maintenance page will be left up.

The theft is being reported to — and we are co-operating with — law enforcement.

As we account for individualized customer losses, we may need to settle open margin positions, associated financing, and/or collateral affected by the breach. Any settlements will be at the current market prices as of 18:00 UTC. We are taking this necessary accounting step to normalize account balances with the objective of resuming operations. We will look at various options to address customer losses later in the investigation. While we are halting all operations at this time, we can confirm that the breach was limited to bitcoin wallets; the other digital tokens traded on Bitfinex are unaffected.

We will post updates as and when appropriate on our status page, We are deeply concerned about this issue and we are committing every resource to try to resolve it. We ask for the community’s patience as we unravel the causes and consequences of this breach.

ETC Margin Trading July 28, 2016

Starting at 12:30 UTC we will enable margin trading for the the ETC pairs ETCBTC and ETCUSD. Margin funding will also be enabled at this time, allowing users to place ETC margin funding offers and bids.

Margin requirements for ETC trading will be identical to those of BTC, LTC, and ETH: 30% initial margin (3.3x leverage) and a 15% maintenance margin requirement. Positions on ETC pairs can be backed with BTC, USD, ETH and/or ETC.

Please note that we cannot extend ETC margin trading privileges to our US-based customers at this time - we apologize for the inconvenience.

Ethereum Hard Fork Plans July 15, 2016

Today the Ethereum foundation announced plans for an Ethereum hard fork to recover the funds from the DAO exploit.

This hard fork is planned to occur at block 1,920,000, which should be on July 20th or 21st depending on your time zone.

In anticipation of this hard fork we will suspend all deposits and withdrawals starting at block 1,919,744 (approximately one hour before).

We will reenable deposits and withdrawals when we are confident that the longest valid chain has been clearly decided.

During this time exchange trading, margin trading, and margin funding will all continue to operate as usual.

Upon re-enabling deposits and withdrawals we will put up a notice on the website as well as, and Twitter (@bitfinex), so please monitor any one of these mediums to stay up to date.

If you have any questions don’t hesitate to let us know, you can email us at [email protected]

Scheduled maintenance June 16, 2016

June 17th at 14:30 UTC (7:30 PST, 10:30 EST, 22:30 HKT) we will be making infrastructure upgrades that require us to pause all site operations for the duration of the upgrade (~60 minutes).

This marks the completion of the infrastructure upgrades being made over the past couple months.

We will be sure to keep everyone updated on, Twitter @bitfinex, and Reddit /r/BitcoinMarkets. If you have any questions or need assistance during this time feel free to contact us at [email protected].

Bitfinex and CFTC reach settlement June 02, 2016

Today, the United States Commodity Futures Trading Commission (CFTC) issued an order instituting proceedings against BFXNA Inc. (BFXNA), an entity that conducts business with U.S. customers through the website In the order, the CFTC accepted BFXNA’s offer of settlement to resolve certain alleged violations of the U.S. Commodity Exchange Act (the Act). A copy of the order is here. In the order and settlement, the CFTC found that BFXNA violated sections 4(a) and 4d(a) of the Act. BFXNA neither admits nor denies the CFTC findings in the order and settlement.

Bitfinex proactively contacted the CFTC in September 2015—before the CFTC announced enforcement action involving bitcoin trading platforms—to provide information about Bitfinex related to a potential investigation. According to the order, "Bitfinex’s cooperation with the Commission’s investigation was significant … Bitfinex consistently responded to requests for information fully and quickly, both in writing and via oral presentations."

In response to these constructive discussions with the CFTC’s Division of Enforcement, BFXNA has made significant changes to the way in which U.S. customers engage in financed trading on Bitfinex. Bitfinex remains committed to continually improving its customers’ experience while complying with applicable laws and regulatory requirements.

In closing, we are pleased to announce this settlement with the CFTC. The CFTC has engaged in a productive, open, and timely dialogue with us, and, as a result, we believe we have a better understanding of the regulatory framework governing financed trading on our platform. The Division of Enforcement has demonstrated that, while they will work diligently to enforce existing rules even as they apply them to new markets, they also are sensitive to innovation and development in sectors that the CFTC regulates.

We look forward to providing best-in-class service to U.S. customers. We will continually work to make our customers’ experience safer and better.
