Thanks for the small piece of history I wasn't around for. Was Bitcoinica really the first to offer leverage?

Yup, they were the first to offer leverage or any sort of short-selling for BTC.  All the orders went through MtGox, and all the funds were stored there as well as I understand it.  So when MtGox went under, it took Bitcoinica down with it.

Ahh yes, Bitcoinica.  That was a fun place while it lasted Smiley

Very minor oversight in my highly predictive scientific math model. I have updated OP to account for small error. Otherwise, model still perfectly scientifically on track.

It needs another update...

Updated my model.

OMG, I come back to this forum after 10 years and @proudhon is still here?  I didn't expect any of us the old timers to still be around.  Last time I remember hearing your bearish wisdom was when BTC was < $100  Cheesy

It appears that CampBx's withdraw by check feature may be available again.


When did it disappear?  I put in for a check withdrawal a little over a week ago.  Looks like the money was deducted from my account last week sometime (I was on vacation).  Haven't checked the mail to see if I got the check or not yet though.

Not a lawyer or an accountant, but my understanding would be that you could claim it as a capital loss.
6  Economy / Service Discussion / Re: Prediction: CampBX is on it's way out on: March 31, 2014, 12:00:53 PM
I've been using campbx for a while. I hope they get a new bank and stick around.

Their trading engine has much improved over there years, not sure what some people are talking about.

Same here. Have never had issues with them.

I've been using them for a long time now and never had any issues.  I do wonder how they continue to operate with such low volume though.  My best guess is that their Bitcoin exchange is a sideshow part of another business they have that is actually profitable and that's how they've continued to stay in business.

Just noticed as well that it doesn't force you to use HTTPS for the login, so if just go to mtgox.com without explicitly using https://mtgox.com you may be submitting your username/password oven an unencrypted channel.

busoni, you need to shut down Poloniex now and try to make your users whole from your own funds and debt. Do not continue trying to run an exchange. Your post mortem indicates that you do not have sufficient programming ability to handle other peoples money - no mention was even made of database transactions, which are a basic "database programming 101" topic. Your proposed fix of checking for negative balances is wrong and indicates that your code is almost certainly riddled with other exploitable bugs.

Please do the right thing and refund everyones outstanding balances, then wind up your operation.

This was my thought too.  At the risk of simplifying things too much, a fix for this might be something like (pseudo-codey):

BEGIN TRANSACTION
INSERT INTO Ledger ...
UPDATE UserBalance SET balance = balance + @amt WHERE user_id = @id AND (balance + @amt) > 0
// if previous update didn't update any rows, rollback
INSERT INTO WithdrawalQueue ...
COMMIT

Bonus points if you digitally sign the records in the database with a private key known only to your application to help guard against direct database manipulation.

But as someone writing financial software, he should have known this already.  Of course it could just be an oversight on his part (everybody makes dumb mistakes sometimes), but if there are bugs like this, there are likely other data consistency bugs that can be exploited as well.
9  Economy / Speculation / Re: Proofs that Gox have at least 200k BTC - lost keys most likely not theft on: February 27, 2014, 04:59:16 PM
Yeah, that shows they had it in 2011, but doesn't prove they have squat today.

It does prove that the BTC is owned by mtgox and the BTC is STILL there.... assuming the IRC is not faked. which means the question is:
Does mtgox have the private key for these addresses?

Ahh, gotcha, I misunderstood.

11  Economy / Service Discussion / Re: Official Money Lost in Mt. GOX Thread on: February 26, 2014, 04:09:24 PM
about 23 BTC
12  Economy / Speculation / Re: Official End of Mt Gox thread on: February 20, 2014, 10:43:24 PM
and the surprise is?

to my knowledge there has yet to be a single long term business (years) whose main focus has been bitcoin that hasn't either

1) been hacked and lost a whole lotta stuff
2) pulled a runner
3) scammed everyone in some way
4) been shut down and lost peoples stuff


I think CampBX would qualify there.  Can't think of anybody else though.  Maybe Cassicus if you count that.
13  Economy / Speculation / Re: Is there even 1 person on this site who thinks mtgox btc holders should sell? on: February 20, 2014, 06:24:02 PM
I have about 22 BTC there.  It's a gamble that they'll come back, but I'm HODLing for now.
14  Economy / Service Discussion / Re: Anyone else got bitstamp btc withdrawal problems? on: February 20, 2014, 04:06:49 PM
a user reported that withdrawals work if you have 2 factor enabled.

can we get a confirmation?

I also have 2 factor, and it looks like I can withdraw just fine. 

I didn't actually try to make a withdrawal, but I don't see the error message on the withdrawal page that others have mentioned (just the usual withdrawal form)
15  Economy / Speculation / Re: Official End of Mt Gox thread on: February 20, 2014, 03:14:10 PM

If Mt.Gox will allow withdrawal of bitocoins -> price will drop hard


Why do you assume this?  From what I've seen the bid sum on Gox has dropped massively over the last few days.  This tells me people are reluctant to buy (obviously).  But where is that money going?  It certainly isn't being withdrawn (we all know about the huge fiat withdrawal delays).  So it's sitting in people's Gox accounts. 

So what happens when/if bitcoin withdrawals are restarted?  People who want to get their money out will buy bitcoin, send their coins elsewhere and sell them - just as they've been trying to do for the last few months.  People with low ask orders will cancel them now that they know they can send their coins elsewhere and get more money for them.  This causes the Gox price to skyrocket and prices elsewhere to (maybe) drop moderately.  And we end up right back where we were before this whole malleability mess - with a Gox price higher than everywhere else.

I've been doing this since 2011, and a year is an awfully long time in bitcoin land.  I wouldn't be making predictions a week in advance much less a year.
17  Economy / Service Discussion / Re: NEWS: MtGox resuming withdrawals on: February 19, 2014, 10:10:16 PM
Roger Ver is a decent target.  Roger Ver associates with gox. Fuck gox.
Roger Ver is a convicted felon.

Yeah, but that was for selling explosives on e-bay.  Doesn't get much cooler than that  Smiley
18  Economy / Service Discussion / Re: Mt Gox frequently not matching orders at market price - anyone know why? on: February 07, 2014, 03:09:45 PM
The ticker thing has seemed to be inaccurate with these kind of things, what do the charts at bitcoinwisdom or bitcoinity say? Often the ticker will show a much lower low than any trade that actually went through...no idea why but it was already doing that many months ago before I stopped using them.

The charts from BitcoinWisdom show the dips below my buy order.. I learnt ages ago that the MtGox chart was useless. I messaged MtGox support about this yesterday and I see this morning my ticket is still awaiting assignment!!

I've since cancelled my buy order and will be transferring all my funds out to a *real* exchange..

What a steaming pile of ______!!!

Really?  Not saying your wrong here, but I've done a lot of trading on Gox and I've never seen that happen.
19  Economy / Service Discussion / Re: Mt Gox frequently not matching orders at market price - anyone know why? on: February 05, 2014, 10:31:24 PM
The ticker at the top of the site has always been inaccurate for as long as I can remember.  I always just ignore it.  Last I heard from Gox they said it was something about multiple currencies and conversions or some other such nonsense.

If you watch the trades go by on bitcoinwisdom.com or any other real-time charting site you'll get a much better picture of what is *actually* happening.
20  Economy / Speculation / Re: OVERSTOCK SHARE DROPPED ALMOST -20% TODAY!! on: January 30, 2014, 05:15:19 PM
Curious why it dropped, anyone know? I tried googling but I got nothing informative.

I know years ago Overstock was famous in the markets as a target of short sellers.  I know the CEO complained about it pretty regularly.  Could be that it still is today (haven't checked the short interest in that stock laterly)
