Bitfinex Bitcoin Cash BCH Distribution Update August 02, 2017
August 02, 2017
BCH Distribution Update
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 user’s 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 Bitfinex’s 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.

TLDR VERSION:
You only get 85% of your BCH rather than a 1:1 ratio. They ripped me off :(
Yes indeed, I too was expecting a 1 to 1 ratio of disbursement and was also disappointed. I received about 85% as well. However, according to Bitfinex's statement, they received a certain amount from the BCH source and divided it up equally amongst their BTC holders. So either they were shorted by the source or they charged their users a disbursement fee and that is how I see it.
