Once split, the BTC will be removed from your account for each BCC and BCU added. Through the same Token Manager, you will be able to reverse this process at any time, trading in equal numbers of BCC and BCU to extract BTC.

A minority of Bitcoin miners will be forking on August 1st, 2017 to create a new chain called Bitcoin Cash. The fork does not impact Bitcoin balances, but it creates a new token. At the time of the fork, all Bitcoin addresses holding a balance will automatically have equivalent balances in Bitcoin Cash.
There has been a variety of responses by the community about how to handle this new token. After a significant show of interest from our customers, we have decided to take steps to facilitate the distribution of Bitcoin Cash balances to those holding a settled Bitcoin balance on Bitfinex. We may also list markets for this new token, but that decision will be made after the fork event.
Although we see this token referred to as BCC on other platforms, unfortunately, that ticker symbol is already in use on our platform by the chain-split token representing Bitcoin Core. As such, we plan to use BCH as the ticker symbol and Bcash as the descriptive name to avoid confusion with Bitcoin.
Although several months ago, we developed a methodology for handling contentious hardforks, we will be applying a different methodology for what we regard as a spurious forking of the Bitcoin project with little mining support. Although we have not supported such Bitcoin UTXO-based distributions in the past (Stellar Lumens, Clams, etc.), we will support the distribution of Bitcoin Cash due to significant customer interest.
Distribution Policy
BCH will be distributed to settled bitcoin wallet balances as of the UTC timestamp of the first forking block, which is expected to occur on August 1st, 2017.
The token distribution methodology will be:
All BTC wallet balances will receive BCH
Margin longs in BTC/USD and margin shorts in XXX/BTC will not receive BCH
Margin shorts in BTC/USD and margin longs in XXX/BTC will not pay BCH
BTC Lenders will receive BCH
Due to the net amount of BTC committed in margin positions at the time of the fork, the above methodology may result in Bitfinex seeing a surplus or deficit of BCH. As such, we will be resolving this discrepancy in the form of a socialized distribution coefficient. For example, currently, there are more longs than shorts on the platform, causing a distribution coefficient of ~1.091 (Meaning that for each qualifying BTC a user will receive 1.091 BCH). The actual coefficient will be calculated at the moment of the distribution. Please note that if there are more shorts than longs at the fork event, this coefficient will be less than one. This coefficient can be roughly computed from publicly available information from our API (longs & shorts) and the Blockchain (cold storage).
We recognize that this model is not perfect, but given the short time frames imposed upon us, better choices are not available. It would be an undue burden to create negative BCH balances for BTC/USD shorts and XXX/BTC longs. Furthermore, lenders may be locked in for up to 30 days and would be adversely impacted. In the end, we believe that this solution creates the least amount of disruption and facilitates a timely distribution of BCH.
Margin longs who wish to receive BCH should consider either claiming some or all of their position or exchanging and holding BTC collateral in their margin wallet as opposed to other assets. We hope to make withdrawals available soon after the fork, assuming everything is fine with the BCH blockchain.
Once again we want to reassure our customers that your bitcoin is safe and this event will not affect your bitcoin balances, positions, or loans - you will simply be receiving an additional token balance based upon the aforementioned methodology.

Bitcoin Cash (BCH) distributions have been calculated for qualifying Bitfinex users, and corresponding balances have been credited. Balances were aggregated across wallets with the resulting BCH being credited to each users Exchange Wallet.
What follows is an explanation of the calculations and adjustments used for determining the distribution coefficient.
The Numbers
After the fork, Bitfinex held 101,798.8855 BCH to distribute coming from 131,237.8562 BTC in settled wallet balances and -29,438.9707 BTC in unsettled margin positions, resulting in a distribution coefficient of 0.7757.
However, after adjustments for manipulation attempts (outlined below), the final coefficient used for distributing BCH was 0.8539
The Situation
The intent of the BCH distribution mechanism was to protect lenders who were already locked into loans at the time of the announcement and to avoid distributing negative balances to shorts on an uncertain value of an unproven digital asset.
With this intent in mind, the BCH tokens were distributed with an adjusting factor to account for long/short imbalances in gross margin positions. Accordingly, as shorts would not have to pay BCH, we believe it was fair and symmetrical to not credit margin longs, yielding an adjusting factor that historically seldom varies more than 10% when compared with gross balances.
After the methodology announcement on July 27th, several accounts began large-scale manipulation tactics in an attempt to obtain BCH tokens at the expense of exchange longs and lenders on the platform, causing the distribution coefficient to artificially plummet.
We have determined that this kind of manipulation - including wash trading and self-funding shorts - is in violation of Bitfinexs terms of service. Those who intended to take unfair advantage of the circumstances surrounding the BCH distribution at the expense of other users have been sanctioned accordingly.
The Resolution
Upon careful review and analysis, we have decided to disallow any hedged BTC balances in excess of any such hedged balances that may have existed at the time of the July 27th distribution announcement. While this may be disappointing to some, it is welcome news to the many users with bona fide BTC exposure through settled wallet balances. This adjustment increases the distribution coefficient from 0.7757 to 0.8539.
We do not take this action lightly. The inadequate timelines imposed upon Bitfinex forced swift action when addressing and remediating this situation. Our purpose has been to distribute all BCH to our users in the fairest way possible. Given the aforementioned restrictions, with our corrective actions, we believe that we have made good on that promise.
The Future
The next step is to monitor the forked network and open BCH withdrawals. We expect BCH withdrawals will be opened within the next 24 hours.
Regarding the possibility of adding BCH trading pairs, we continue to monitor the market. BCH deposits will only be enabled if and when BCH markets are created.
We will have another update within the next 48 hours to address these potential next steps.
