For anyone that's completely clueless in this thread, having actively traded on Bitfinex for a decent duration of time in the past, I can say for 100% fact that a single entity controls the bitcoin price using that exchange since bitcoin was $200 and this entity longs and shorts, but spends most of it's time trying to raise the price.  They try to crater the price to accumulate, then raise it.  It's a classic pump and dump.  

From observing this entity, I'm also postive the Bitfinex exchange owners are in on this operation.  It's either the exchange owners themselves doing it, the Chinese mining cartel, or some giant TBTF bank like Goldman Sachs.  The main reason I throw the TBTF banks in there is because this entity seems to be completely above the law while a normal person would already be in jail for the stuff Bitfinex has done.  Then there was also supposedly $400 million in drug money seized in Poland that was affiliated with Bitfinex and not a damn thing happened to them.  Kind of reminds you of HSBC being caught laundering $800+ million in drug money.
