Bitfinex is not a financial services business run by competent, experienced professionals.
Bitfinex is not built from the ground up on sound principles of engineering.
Bitfinex was copied from the leaked bitcoinica codebase, a Ruby-on-Rails app written by then 16 year old Ryan Zhou.
Saying "they reverse-engineered it" would be overly charitable.
Bitfinex was released within some weeks of the Bitcoinica source code leak.
The codebase was copied from a defunct, thrice robbed company.
That code is not capable of keeping the database consistent at peak loads.
That code is not scalable. That code was not, and is not correct.
Not correct according to specification. (Which doesn't exist.)
Not correct according to expectation. (The business logic of the exchange is broken.)
This becomes evident as the load on their server approaches capacity.
Everything goes to shit. Time and time again.
Their database stuff seems limited to concurrent reads, but single threaded writes.
It is a product of inspired design, not engineering.
It is very far from being remotely acceptable for a financial exchange.
But at least they have been making money since day one.
(Because they had essentially no development costs, starting out.)
There is a good story here, waiting to be written by some investigative journalist.
Perhaps we will have to wait for some catastrophe before that happens.

This alone is a reason not to use it, I still have domains stranded in that gobshites domain registrar (nameterrific) that was first to accept bitcoin
I hear he is now running coinjar in Australia, pitty the fools who use that now

Bitfinex - Pretty sure we are dealing with amateurs here (self.Bitcoin)

The title says it all - consistantly over the past couple weeks we have experienced issues such as:
Ghost orders (placing margin shorts and longs when you never did)
Closing orders on their own
Not closing active positions
Unable to cancel orders
Not filling buy or sell orders (on the way up or down when under load)
Doubling margin when you don't have the required margin to cover it (WTF???)
What is the excuse? Don't hit the button more than once. Well I never did and it appears they put in a fix that notifies you when you hit it multiple times. Who cares. That should of been FIXED. Regardless - this exchange is considered mature and "world's largest". Then why the hell would they send service outage notices ONLY on twitter?
They don't have a problem sending you emails when you login or when you are getting margin called but they cannot send you an email when service has been interrupted or resumed? This is a complete joke. Everybody doesn't have twitter and further more - where is the incident management process in place? THERE IS NONE!
TLDR; we are dealing with amateurs. They clearly lack the Technology talent in regards to programmers and infrastructure staff to make things scalable. Sure they made some behind the scenes security posture stuff. GREAT! That is to be expected.
I will be moving my coins and going to another exchange. I suggest you do as well before things get real bad.

I have been able to withdraw 40+ BTC multiple times without any issues. They were always processed almost immediately with a transaction being broadcast prior to the next block being found. The only delays I have ever experienced with them was during the stress tests however I believe that was due to the unavailability of confirmed unspent inputs.

Their number and severity of problems is small IMO

I bet your "Chinese arbitrage trading team" must be moving large amount of fiat, particularly USD across different banking systems?
You cannot stop the "evil US government" from studying you when you are moving large amount of their currency around the world.
I never have any issues withdrawing USD or BTC from Bitfinex

No, he was withdrawing the Bitcoin.

I have been in the Bitcoin community since 2011 and now I smell something that is not right about Bitfinex recently. I believe it is the right time to start this post, to let the community to have a full records of the ongoing history. I also want to start this post to let the whole community watch out for this risk. People are still using Bitfinex, and the trading volume of Bitfinex is still among the largest. However, I have already find the clue of fraud, and the evidence of amateur.

This unregulated exchange is a huge risk for the Bitcoin economy. We need to let more people to know about the risk associated with this exchange, and we should let other traders know.

I am living in China and getting communicated a lot with the bitcoin community there. On 14th Aug, the COO of btc123.com, Chandler Guo, has removed bitfinex from their list of quotations.

btc123.com  remove bitfinex 4days ago!

Chandler shared a very important piece of information in a Wechat group, indicate that a China arbitrage trading team have find issues when withdrawing bitcoin from the Bitfinex exchange. Soon, I myself get confirmed from the leader of the team, Mr. Zhao, confirmed it. He said that he had to "rummaged around" the whole Bitfinex contact list and trying every way to have a respond, and then got the Bitcoin withdraw done. The bitfinex give him an excuse of something with the evil U.S. government seizing their fund. This has never happened before. Mr Zhao showed us the email:



Evil U.S. government are seizing our fund. The withdraw is slow. Signs of market manipulation. Doesn't it looks pretty familiar? When we find signs of similar problems with mtgox, mtgox is not shutting down immediately. The whole situation of mtgox evolved in about 10 months time.

Now it is the time to be very cautious for us to look into what is happening with Bitfinex. And for those who are not trading there, I believe you will have a good time to look at the show in the next months.

I don't know about that.
Shit like this happens every 2 months
We're still trying to make it work.
even if you try via API?
Uh Uh. No. Look I understand guys. No.1 rule of trading. You press the bottom once it doesn't you don't press it again. OKAY?"
I believe it's a bug we fixed a long time ago. Maybe."
