In Short,
"CoinSetter.com",
No 5-Day Holidays in the Western Hemisphere,
They are out of New York and sent me an invite !
https://www.coinsetter.com
In the Western Hemisphere !

Appears to me that Exchanges in the Eastern Hemisphere
such as BitFinex, BtcChina, Huobi, ANX, MtGox and worst of all Global,
have little or no concern for their Western Hemisphere Customers.
Just because the world comes to a complete stop in the Eastern Hemisphere / China,
does not make it so for all the world, any company doing business on a International Level
should be aware of this, only serves to a loss in Customers to ignore it.

Don't think that either one of my LandLords want to hear,
"Sorry, I'm waiting for my funds to arrive from China / Hong Kong, but they are on a 5-Day Holiday",
Does not quite cut it or fit the bill.

They changed the bank to Hong Kong to avoid the new China Regs because Hong Kong is a Special
Economic Zone at least until whatever year in the future before China also ruins that zone, it was not
in an effort to serve their Western Hemisphere Customers any better, it was self-motivated with their
own interests in mind.

Another Freaking Holiday, Perfect !
even more so now . . . .
If they knew they had a "National Holiday" coming up,
then they should have put that "Stupid Withdrawal Policy"
aside and took care of their International Customers,
No one wants to wait a Freaking Week for a Withdrawal
to take place, it's their Holiday(s), not ours !

Think I will give these guys a try, "CoinSetter.com",
They are out of New York and sent me an invite !

Fiat / USD

Previously before this insane new withdrawal policy
one could make a withdrawal / wire and it would hit your
account inside of 24 to 48 hours !

Not the same BitFinex anymore, guess they are trying to preserve their liquidity,
at our expense, pay the fee or wait, basically holding the cash as "Hostage"
maybe a better word would be leverage, but still all the same !, has put me in a tight spot
have a move planned in the next two days on Feb. 5th and these guys have not even processed my
withdrawal yet, will end up having to pay this current landlord even more cash !, gee Thanks BitFinex !

Only a "Hacker", a "Terrorist" or a "Troll" like yourself would actually try something like that out,
My purpose is simply a warning, another Genius, just what the world needs, Go Figure !

Also for the record,
Tomorrow, Tuesday,
will make 1-week from
Wednesday last week the 29th
since I made my withdrawal request,
and it still reads, "PROCESSING"

You guys need to really take a look at
that new withdrawal policy you have implemented,
Don't see how anyone could think that is good business practice,
You are only going to lose customers behind having a policy like this in place.

Seriously !

Frightening. This is truly scary.

REDDIT TITLE:
How I stole roughly 100 BTC from an exchange and how I could have stolen more!

http://www.reddit.com/r/Bitcoin/comments/1wtbiu/how_i_stole_roughly_100_btc_from_an_exchange_and/

Question,

Is BitFinex's Platform A.C.I.D. Proof ?

Basically financial software often deals with online transaction processing, which is basically what traditional, SQL-based database management systems are made for, they guarantee ACID:

    Atomicity (processed as a whole, e.g. if transaction moves money from account A to B you cannot get to a situation when only one balance is updated)
    Isolation (concurrent transaction do not interfere with each other)
    Consistency (data always satisfies constraints)
    Durability (data is stored permanently after transaction is committed)

In computer science, ACID (Atomicity, Consistency, Isolation, Durability) is a set of properties that guarantee that database transactions are processed reliably. In the context of databases, a single logical operation on the data is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction.

    Jim Gray defined these properties of a reliable transaction system in the late 1970s and developed technologies to achieve them automatically.

    In 1983, Andreas Reuter and Theo Härder coined the acronym ACID to describe them.


SOLUTION:

OP managed to trick the exchange's database into forgetting he withdrew 100 BTC by simultaneously selling off several 0.0001 BTC units and getting one of the small transactions to clash and overwrite the large withdrawal.

So both operations read his balance of X BTC at the same time subtracted 100 BTC and 0.0001 BTC respectively. The first operation wrote back the balance of x - 100 into the database and the second operation then overwrote that balance with x - 0.0001, effectively giving OP back those 100 BTC.

One of the most basic things you need to take into account when implementing a database is record locking, to make sure only one operation can access a specific bit of data at one time and that any operation must relinquish control before another operation is allowed access, to make sure such clashes don't occur and corrupt the data.

Sounds like I hit a nerve,
Right on target, just as I thought,
Freaking Children !

You are speaking with a grown man with kids,
Don't have time to carry-on with un-developed minds,
Guess that would make sense being that you're from "Third World Un-Developed Countries"

Careful a little gift from the USA, the next "TomaHawk Cruise Missile" or un-manned  "Drone" just may be coming your way,
Freaking Muslim Terrorists trading BitCoin !

When you guys stop living with your parents, we might start to respect your opinions, as previously mention, in the USA we leave home at the age of 18 years old, that was many moons ago, whereas you guys live with your parents all your life never learning responsibility simply waiting for your parents to die to inherit the house that your Great-Great-GrandFather built, who was probably the only person in your family that ever knew what it meant to be an adult and make your own way in the world because every since then you have all been living in the same house, you could never survive in the USA because your mind has never developed into a adult's mind, basically a child's mind inside of a adult's body, it's that way in the majority third world countries, children that never really grow up and learn responsibility, never having left home in your entire life besides a school or college field trip, pathetic children !  

How do I know this you might ask ?

Because the majority of people trading BTC are from Third World Countries,
you trade BTC just to try to be able to make a decent income because your
own Third World Country's Currency is sucking wind and is not worth anything, lol !

Now go back to your room in your parents house and close the door, they may just
let you be excused to go to the bathroom if you ask nice enough, until then play with
your PlayStations an X-Boxes like the kids you are, lol

Thanks Chief,

I'm a member of:
https://www.TradingView.com
Primarily for the lack of a finding a good
BitFinex Chart to work off of that I can use indicators,
of which even they don't offer, I use their BitStamp chart
which is close but still not quite a BFX Chart, I'm aware of
BitCoinWisdom's BFX Chart, but BitCoinWisdom is no TradingView.com.

I've sent at least 3 to 5 people / referrals who've opened accounts at BitFinex,
They keep asking me for a "Referral Link" which I take as a affiliate link, my response
has been "Those are given out upon Request".

It's not that my Wife or I for one moment had any doubts in the Character of BitFinex,
but we are aware that bad things sometimes happen to "Good People", like Regulation Traps.

Which would not be a reflection upon BitFinex but more of the Chinese Government again,
having come into this market two days before the "China Exodus" on Dec. 5, 2013 we are all
too aware of the effects of China's Regulations, we took a serious dent just from that.

We watched this market make a five-times fold in Nov. 2013 when we found btc at $200 per btc,
by the time we got all of our KYC/AML regulatory requirements out of the way btc was at $1100 per btc,

Trust us when we say that we are not big fans of regulations, especially Chinese Regulations at this point.
Witness "Five-Fold", we come into the market and two days later the bottom drops out due to China, thus
leaving us with the market we have today, and now even more Chinese Regulations.

First no banks, secondly no third party money transactons like PayPal or AliPay, now no ClearingHouses,
The Chinese Govt. have all but murdered the Chinese Exchanges which all but lead the Nov. 2013 rally,
and still no one makes a move at https://www.TradingView.com without first seeing what Huobi
is doing first, it was BtcChina who the Chinese Gov. dropped the hammer on, now it's Huobi.

Thanks Chief,

Guess this whole "New Years Chinese Regs"
Has me on edge, I imagine that answers my previous question
as to if the EMail Confirmation is also delayed for 3-Days, this
entire 3-Day deal is something new that's been implemented.

If so would it not be better to send out an immediate confirmation
something stating to the effect of :

"Your WithDrawal Request Has Been Received and will be processed within 3-Days" ?

My only concern now is that a 3-Day deal puts me inside of this 5-Day Chinese Holiday,
will that add another 5-Days to the 3-Days for a total of 8-Days waiting time before the
process even starts ?

Give it a shot and see what happens,
I would love to know that it's not just me,

previously everything has gone really "Smooth" with BitFinex,
This time I'm sitting on edge, not to mention that my Wife and
I have a move scheduled coming up in the next couple of days,
This is really screwing things up for us.

Wow,

I don't believe it,
Somenone from the BitFinex Team
logs back into this chat and does not address
my "WithDrawal Concerns" mention about eight posts up,
https://bitcointalk.org/index.php?topic=229438.msg4847372#msg4847372

2-Days later, Funds Deducted, but No EMail Confirmation,
This is strange / odd, normally the "WithDrawal Approved"
EMail Confirmation Arrives within hours after making the request,
still reads "Processing", Are you having "Problems" in China ?

I originally sent funds to the China Account, with all the concerns that everyone is having regarding the new Chinese Regulations
I would think that this "WithDrawal Concern" would be a FIRE that you most definitely want to put out quick and in a hurry.

Would really due for BitFinex to address the "Customer Service" issues that everyone here seems to be mentioning
versus just leaving us hanging with no answers, geez !

Who am I but a Lowly Customer concerned about a "Withdrawal" that's obviously not worthy of a response.

Made a "Withdrawal" yesterday 24-Hours ago,
Normally I get a notice sent to my EMail:



Hello,

Your withdrawal #XXXXX, of XXXXX USD via WIRE, has been approved. It will be processed within the next business day.

Regards,
The Bitfinex Team
https://www.bitfinex.com/



This time I have not received that confirmation,  .
The request was made Jan. 29, 2014
I'm just wondering if this notice of yours affects it in any way ?
The withdrawal request was made before the Chinese New Year Banking Holidays,

Chinese New Year Banking Holidays
Posted: 27 Jan 17:00

Dear customers,

During the Chinese New Year, from the 31st of January to the 6th of February, our deposit bank will be closed for the holidays.
To avoid any disruption of service, we temporarily accept deposits on our other bank account for which details can be found on the Deposit page.

Best regards
The Bitfinex Team


I understand the:

"Wire withdrawals will be processed within 3 business days, unless you request the option "Express".

However the 3-Business days will place the request within the Chinese New Year Banking Holidays,
Will this affect the processing of this withdrawal ?, ,  and lastly if one does not choose the 24-Hours Express
Option does this affect when one receives the EMail Withdrawal Confirmation ?,  

Withdrawal Request still reads:  "Processing"

Wow,

I'm not even a customer yet and I can tell you
that your current customers are not going to be "Happy Customers"
with that, scaling them down to just the functions of their current bot,
you need to remember that it's your previous customers that got you to this point.

Kick In Like a Friend and Share The Wealth With Your Current Customers,
You really appear to be one Selfish S.O.B.,  excuse my French, but it's true !

Don't think that I will be purchasing, you treat your Customer like CRAP !, I'm Out.

Blah, Blah, Blah,

What's the price for NEW Customers ?

He was kidding, he was not being serious, did you not see his last words, "in a dream or something".

We all know that BitFinex is the BEST, now if everyone else will just come to that realization !, some day maybe.

Understood,

Thanks Chief

I guess it's like running a "Un-Managed VPS"
they expect you to have enough knowledge
to stand on your own two feet and not do
Stupid Sh_t, like make WithDrawals right before
a freaking Rally starts, :-( ,

But still a "Cancel WithDrawal" Button would be handy, :-) ,
Especially while the Withdrawal is still in "Processing" stage,
Like up to at least 2 to 3 hours to change your mind.

A Salute To The BitFinex Team,
Happy New Year !
May It Be a Prosperous One For All of Us !

I'll take a "No Response" as a No,

Thanks

Is Cancel WithDrawal anywhere on the horizon ?,
Made a withdrawal right before this rally started
and Man did it ever bite me in the rear-end.

A Cancel WithDrawal would be nice.

Thanks
