Bitfinex Security Breech: https://t.co/9Y56DYoSDn— Bitfinex.com (@bitfinex) 2 August 2016
Trading on Bitcoin markets reached panic selling, realizing a decline of more than 8% starting within 15 minutes of the announcement from Bitfinex. Since Bitfinex is the top Bitcoin exchange including an active margin trading facility the effect throughout Bitcoin markets is significant. However, prices are scattered across the board where Bitstamp trading aggressively down to $555 whereas Chinese Bitcoin exchange Huobi is firm at $575.
We have yet to hear about the scope of the theft that Bitfinex is experiencing so we do not yet know the damage incurred to the exchange.
“Bitfinex is the biggest Bitcoin trading exchange. It’s margin accommodation brings a lot of liquidity to the market. That is missing until they bring operations back online. Until then prices can be volatile. Definitely can attribute the decline in price to the exchange being hacked, however this could signal the entry point to many traders,” comment from Daniel Dabek, Founder and Architect of Safe Exchange and curator of Alt Coin Trading Community.

"No accusations but markets never change. Before every unexpected news announcement in almost all markets there is unusual activity. There was a big sell off before the Bitfinex security breach and that normally means somebody somewhere had good knowledge to short ahead of the fact. We can now speculate on the reason for the sell off and after seeing it time and time again I am more inclined to believe some big short sellers knew what was coming. This is not unique to crypto markets. "
