All accounts and assets on Bitfinex will collectively lose 36.067% due to socialize losses. This information was provided in Bitfinex latest blog post.

Bitfinex intends to return the site back online with limited functionality within the next 24-48 hours. Users will also see inside their accounts a new token called BFX. BFX is intended to replace customers losses and will remain outstanding until redeemed or exchanged by Bitfinex at a later date. The BFX token might also be exchanged for shares in iFinex Inc. the controlling company of Bitfinex. So to repeat ALL accounts and assets on the Bitfinex exchange will be forced to take a haircut of 36.067%. This socialized loss is across the board.
