381  Economy / Marketplace / Re: Where can you spend Bitcoins on Gold or Silver? on: September 11, 2013, 04:41:59 AM
I would like to know for the future.

As always, buyer beware - consider using escrow if you aren't doing the trade locally.

382  Economy / Exchanges / Re: [ANN] KRAKEN.COM - Exchange Now Open with Live Trading EUR, BTC, LTC on: September 10, 2013, 10:56:27 PM
I have a concern with any exchange that also supports alt-coins, and shared that concern here:

There are four specific scenarios I would like to know what Kraken's policy is should they occur:

A.) My Kraken exchange account holds only fiat and bitcoins, and I've never traded for Litecoins.  Would I be exposed to any risk of loss to those funds should there be a successful 51% attack against Litecoin?

B.) I have a balance of Litecoins and fiat, but had no litecoins deposited to Kraken in any block that was ultimately orphaned as the result of the 51% attack.  Would I be exposed to any risk of loss to those funds should there be a successful 51% attack against Litecoin?

C.) I had bitcoins and I traded them for Litecoins.  Following this trade the attacker released blocks that resulted in a double spend such that the Litecoins I received were from the attacker's account (i.e.,  Litecoins deposited with a transaction that no longer confirms or was double spent).  Following the successful 51% attack against Litecoin, do I still have Litecoins that I can withdraw (or trade back into Bitcoins)?

D.) I deposited litecoins from a block that utimately was orphaned as the result of a successful 51% attack against Litecoin.   Before the attack I was able to trade those litecoins for bitcoins which remain in my account.    After the successful 51% attack against Litecoin, do I stil have the ability to withdraw those bitcoins?

I imported a private key and now I have the correct address in my account and the account has the BC in it but it's not showing in my wallet.

I'm trying to make a purchase... Help!

Which client?

When you say the "account has the BC in it", are you meaning that using some other source the blockchain shows that Bitcoin address having funds?  Or do you mean something else?

If Bitcoin-Qt/bitcoind, you could try launching with -reindex  [Edit: -rescan ].
384  Economy / Service Discussion / Re: Mt Gox bitcoin withdrawal not working on: September 10, 2013, 09:39:24 PM
Hello all,

I'm failing at withdrawing bitcoin from Mt. Gox... it tells me that my bitcoin address is invalid (it's not). Anyone else having the same issue?

That's something I've seen when they have issues with their back end (bitcoin daemon).

You porbably want to open a support ticket:
385  Bitcoin / Bitcoin Discussion / Re: In-person Bitcoin purchases - no problem! on: September 10, 2013, 10:09:19 AM
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?
389  Economy / Exchanges / Re: [ANN] KRAKEN.COM - Exchange Now Open with Live Trading EUR, BTC, LTC on: September 09, 2013, 05:47:32 AM
> 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!
390  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)?
391  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.
392  Economy / Economics / Re: How long do you think we have? on: September 08, 2013, 05:13:21 AM
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:
393  Bitcoin / Press / Re: 2013-09-03 No Banking, No Bitcoin on: September 07, 2013, 07:17:08 AM
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.
394  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.
395  Bitcoin / Mining support / Re: Can someone (probably a miner) please help? Transaction worth hundreds stuck! on: September 07, 2013, 06:58:18 AM
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):
396  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.
398  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.....
