What do you think?

There's a feature that users have asked for ...  called "Replace by fee".   

This is a patch to Bitcoin-Qt/bitcoind available now to those miners who choose to use it.   A side effect of that is that it would make it significantly easier for those attempting to double spend since a replacement transaction will be recognized simply because it includes a higher fee.

No miners are using that patch today, at least that is publicly known, so this isn't a risk today but merchants who recognize payment on 0/unconfirmed should remain aware that double spending risk could grow in the future.  Today, there's very little risk of a double spend/race attack.

How the hell do I get unbanned some cock sucker banned me about a year ago because I buy and sell for paypal.

IRC ban?

That can be removed by a channel op, and there are several of them.

Try going into #bitcoin-otc-foyer and asking to be unbanned there.

As far as the answer to the question in this thread's title, forum user nanotube is the person who built most of the #Bitcoin-OTC marketplace and the #Bitcoin-OTC Web of Trust (WoT).

I don't think you can create a US account without giving the state.

Ah, appears from looking at the sign up form that you are correct, I just didn't remember selecting a state. 

So, let's say that somehow I selected the wrong state.  Is there a way I can change the state associated with my profile?

When contacting support I would like to encrypt the contents so that only can see the contents of the message.

But I do not see a PGP (GPG) public key listed for

Is there a way to protect my privacy when contacting support?

> In most US states, including California and New York, we offer no services.

I get the notice stating:
"Unfortunately, we cannot offer our services in your area at this time. " without actually sharing which U.S. state I am from.  

Was that decision made based on the IP address?  If so, that's not really accurate at the granularity of states.

Incidentally, ... nice work.   I mean really, ...  nice job!  Asking for my PGP (GPG) key so you can encrypt my e-mails?  Why isn't everyone doing that?   And two-factor.  Not just letting me configure it to require two-factor on withdrawals, but giving me the option to have a separate 2FA OTP for trading than the one I have for withdrawals.   Very impressive stuff!
506  Economy / Web Wallets / Re: - Bitcoin Block explorer & Currency Statistics on: September 08, 2013, 08:55:06 PM
I do like the ability to import a private key and have it sweep (spend) the funds, however the address it gets swept to is another existing address from my wallet.  This re-use of a previous address is not what I want, however I don't see any way I can force this sweep to create a new address for the sweep be spent to.

Is there some other way to import a private key and have it swept to a new address ... either via mobile , or My Wallet (web)?
507  Bitcoin / Development & Technical Discussion / Re: Checking balance of another address from daemon? on: September 08, 2013, 05:28:16 AM
I have tried getreceivedbyaddress and listreceivedbyaddress but they do not seem to work.

It can be done with the Raw Transactions API but not easily.  You'ld use listunspent to get a list of transactions and filter that for the address you are checking on.  [Update: See jgarzik's response below.]

if you weren't needing bitcoind specifically for this then know that other clients including BitcoinJ, Armory, etc., provide access to this info in a different way.

I've just accidentally run into the counter again at Our current debt is ~1,84 trilion CZK (over 90 bilion USD). Budget for this year was 1,18 trilion. That means, probably next year the debt will rise to 2-year budget.

Of course, everything is fine here, nobody worries. I give it decade max, whaddaya think?

They'll hit some limit then just stop updating.

That's what the U.S. Treasury has done.  The national debt has been stuck at its $16.7T limit since the end of May.  Everyone knows the debt has been growing since, they just have taken "extraordinary" measures:

Sure I'll give them my public key....after I generate 10,000 new ones in a second, and never use the registered one again.

Yup -- Bitcoin can be used in ways that are not impacted by AML regulations.  Just as can cash.
510  Economy / Service Announcements / Re: Convert bitcoin to cash for free with Bitcoin-Brokers on: September 07, 2013, 07:05:42 AM
What's different about this one?

With an exchange, all deposits are made to the same account number.

With Bitcoin-Brokers, cash is deposited directly into the seller's account.

The bank has no idea that the cash deposit transaction was Bitcoin-related, so it becomes much harder for them to prevent this activity without scrutinizing all cash deposits (e.g., asking for ID from the person making the deposit).   Of course, a large seller will have many cash deposit transactions and that alone might put them in the spotlight but the bank wouldn't necessarily know that the deposits were the result of a Bitcoin sale without doing much more investigative legwork.

Didn't read the thread, but I think the only reasonable option you can do at this point is ask a pool operator to include the transaction in the next block they mine.

Or give it a little more time to confirm (which is what happened):
512  Bitcoin / Bitcoin Technical Support / Re: I accidentally the transaction fee, what do? on: September 06, 2013, 10:47:41 PM
It turned out that I forgot to include a transaction fee. I'm worried that my deposit address will change before I manage to get the 6 confirmations. How screwed am I?

Well, there's no reason it won't eventually confirm so now it is just a matter of transactions sitting ahead of yours getting included before yours will get in.

But there's no way to speed it up at all, nor any way to cancel it.

I'm worried that my deposit address will change before I manage to get the 6 confirmations.

If this is to Camp BX, the payment has already been sent so their new address expiration policy (which I strongly disagree with, personally) shouldn't be relevant. 

If instead this was a payment to a payment processor, they too show a countdown timer but that is met by the transaction getting broadcast and won't expire if confirmations don't occur in time.

Incidentally, there's going to be a Ripple Dev Con following the large emerging payments conference Money2020 (October 6-10, 2013), in Vegas.  The Dev Con is October 10th.
514  Bitcoin / Bitcoin Discussion / Re: Hardware device and protocol for seeding and verifying Provably Fair gaming on: September 06, 2013, 10:16:17 PM
please explain why Live Dealer is not "Provably Fair"?

Live dealer:

Provably fair with a live game would involve something like the decks of cards being shuffled (however you deem the shuffle to be considered fair), then on each card is printed a unique ID (e.g., serial number like 1 for the top card, 2 for the next, 3, ...etc)   then both sides of each card photographed, digitized and encrypted and the digital content given to you.

So before you place your bet you have evidence that allows you to later know the order of every card in the card shoe before the game.   After the game, you are given the passphrase used to decrypt and, if you know each action each player took, you can prove if the dealer cheated you.

A pretty large Bitcoin contingent will be at Money2020 in 2013.

What a difference a year makes.

I think the only Bitcoin names from the 2012 conference were  ....

BitInstant ... whose principals were there just one day because they had another big gig that same week, and David Birch.  

I don't know that Payward's Jesse Powell was a speaker, but his epic "Bitcoin pitch" at a dinner table one evening during it got written up in this article:

This article is too awesome... Bitcoin FTW at Money2020

Meanwhile in Las Vegas.....

I've previously inquired with, requesting that they take Bitcoin as payment.  Perhaps with enough inquiries they will add it.

That's what happens when you compete in a low margin industry (grocery) but use a high cost payment network (Visa/Mastercard).
520  Bitcoin / Mining support / Re: Can someone (probably a miner) please help? Transaction worth hundreds stuck! on: September 06, 2013, 09:07:22 AM
Having $12 stuck unconfirmed is a lesson learned. But having $500 stuck forever?

It won't be stuck forever.

Firstly, the problem appears to be that the transaction had a parent transaction that had not yet confirmed.   And that parent too had a parent transaction that had not yet confirmed.  Those just confirmed a short while ago (about an hour ago).  So now your transaction is not dependent on any other transactions getting confirmed.

So the problem was you sent a payment before the funds for that payment had confirmed.     Bitcoin-Qt/bitcoind and many other clients don't let you shoot yourself like that.'s wallet doesn't care ... if you want to create a transaction that won't confirm right away, it will let you.  That's a feature experienced users want, but a problem for those like yourself who weren't aware of the underlying issue.

Anyway, there's not much you can do .. it will confirm when it confirmed, generally within a few hours or up to a day from here.

You can see the prior transaction using by going into the Advanced mode (click the link at the bottom of their page), and then click on the (spent) or (unspent) for each address in the INPUT.
