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, bitfinex.com 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, bitfinex.statuspage.io. 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.
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.
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 bitfinex.statuspage.io, 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]
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 bitfinex.statuspage.io, 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].
Due to the Dragon Boat Festival Holidays in Taiwan all banks will be closed on Thursday 9 June and Friday 10 June.

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 www.bitfinex.com. 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.
Starting at 3:00pm UTC on Friday April 22nd we will enable margin trading for the the ether pairs ETHBTC and ETHUSD. Margin funding will also open at that time, allowing users to place ether margin funding offers and bids.
Margin requirements for ether trading will be identical to those of bitcoin and litecoin: 30% initial margin (3.3x leverage) and a 15% maintenance margin requirement. Positions on the ether pairs can be backed with bitcoin, USD, and/or ether.
Please note that we cannot extend ether margin trading privileges to our US-based customers at this time - we apologize for the inconvenience.
Because of the Qing Ming Jie Festival (Tomb Sweeping Day) in Taiwan our banks will be closed on Monday 4 and Tuesday 5 April.
During those days there will be no wire deposits and withdrawals processed.
On Wednesday 6 April the banks open again.
Bitfinex is pleased to announce upcoming support for trading Ether. While we are generally wary of adding new digital assets to the platform and believe that Ether’s future as a store of value is quite uncertain, it is, nonetheless, hard to ignore the Ether trading volumes at other exchanges and the many requests we have received from our customers to add Ether trading pairs. As such, we will begin trading Ether against both US dollar and bitcoin on Monday, March 14th at noon UTC. Starting immediately, however, customers will be able to deposit Ether into their exchange wallets.
It is our plan to allow shorting and margin trading on Ether as soon as we are comfortable with the book depth and availability of Ether for lending, but that will depend on the community’s support for Ether trading on our platform as Bitfinex itself is not a market participant in its own markets. Assuming strong adoption of Ether trading on our platform, we could enable shorting and margin trading in less than a week. We do not yet know what sort of leverage ratios we will permit on Ether, but given Ether’s substantial volatility relative to bitcoin, we may, in fact, initially allow less leverage than we do on bitcoin.
In order to encourage market making to help jumpstart our Ether markets, we will be offering introductory pricing on both Ether pairs. Through the end of March, it will be free to add liquidity (market maker) and 20bps to remove liquidity (market taker). Trading volumes in Ether during this time will not affect volume tiers for bitcoin and litecoin, but after March, Ether will be part of the existing aggregated volume pricing tiers.
We are also actively pursuing the addition of Euro trading pairs as well – we will naturally keep the community apprised of any further developments. Once again, we thank you for your continued support as we strive to deliver the best in cryptocurrency trading.
