I think this should be in "press"

Probably the reason why bitcoin just went down 10% to about 560$.
I did not see this one coming!!!

just copas from their website

Today we discovered a security breach that requires us to halt all trading on Bitfinex, as well as halt all digital token deposits to and withdrawals from Bitfinex.

We are investigating the breach to determine what happened, but we know that some of our users have had their bitcoins stolen. We are undertaking a review to determine which users have been affected by the breach. While we conduct this initial investigation and secure our environment, bitfinex.com will be taken down and the maintenance page will be left up.

The theft is being reported to—and we are co-operating with—law enforcement.

As we account for individualized customer losses, we may need to settle open margin positions, associated financing, and/or collateral affected by the breach. Any settlements will be at the current market prices as of 18:00 UTC. We are taking this necessary accounting step to normalize account balances with the objective of resuming operations. We will look at various options to address customer losses later in the investigation. While we are halting all operations at this time, we can confirm that the breach was limited to bitcoin wallets; the other digital tokens traded on Bitfinex are unaffected.

We will post updates as and when appropriate on our status page (Bitfinex.statuspage.io) and on the maintenance page. We are deeply concerned about this issue and we are committing every resource to try to resolve it. We ask for the community’s patience as we unravel the causes and consequences of this breach.

in bold area, is this same thing like in gox before??

No. Mt.Gox attack was related to Mt. Gox's hotwallet being emptied over many
weeks/months by "transaction malleability" (Or so Karpeles has claimed). It was not
related to an individual user's wallet/address, but site's wallet.

Currently, Bitfinex is saying "some users are reporting" this, so I assume these people
were all hacked (bad pws) or downloaded keyloggers and the attacker decided to grab
everyone's btc within the exchange, at the same time.

The Bitfinex attack is reported to have been conducted today.
So previous BTC market price declines are not related (in theory).

This is my opinion based on current info, which is no real info yet, lol.

Maybe. It could be the reason to the price drop and so its not ETC after all?
I guess the drop will continue still up to a week or so and ETC's price will continue to grow even more. Horray to all adopters.

The rumor I heard is that BitFinex was set up such that although all BTC was held with BitGo, which apparently has reasonable cold storage practices etc., the BitFinex<->BitGo settlement setup was such that anyone with BitFinex's (hot, online) key could withdraw large amounts of money from the BitGo accounts at any time. Exactly how much could've been stolen would depend on how much BitGo allowed BitFinex to "settle" at one time, but I don't know the details of how that worked.

Sort of reminiscent of having a "cold storage wallet" that will blindly follow the instructions of the live server... (Though maybe some limits were enforced.)

I'd suspect that BitFinex is insolvent, though I definitely don't know for sure. Still, I recommend withdrawing everything as soon as possible.

anyone know how much they lost?  cant believe this is still happening so many years after MtGox .... sad 

Could be a minor Mt.Gox event. I also think that Bitfinex could face insolvency. The drop in Bitcoin price prior to the event could mean that larger amounts of funds were withdrawn/converted...
It remains to be seen, if this disaster was an inside job or a real hack. In any case, the hot wallet cold wallet concept at Bitfinex was insufficient to prevent it from happening.

Luckily the exchanges are less monopolized today than 2011-2012. So I think the overall damage to the bitcoin exchange landscape will remain limited. That of course will only be cold comfort for the users affected...

Hopefully, the other exchanges will learn from this and constantly improve their security precautions.

ya.ya.yo!

 At least press of the day.

Right now it seems like a minor thing, but if this problem turns out to be much larger than they wanted us to believe, then prepare for a trip deep into the Southern regions. On the other hand, I'm not that surprised. Everytime the price seems to go up quite a bit, something happens, and the price falls back real hard. For me personally it's not really a problem as trading in a volatile market gives me the best returns, but it's another piece of bad publicity for Bitcoin exchanges in general that will most likely affect the average joe. They directly think in terms of "Bitcoin is hacked". They don't know the difference between a hacked exchange where Bitcoins are stolen, and Bitcoin as technology that got hacked. For them it's just Bitcoin that got hacked.
