2161  Local / India / Re: BUYING/SELLING Moneypaks upto 5000$ on daily basis on: February 15, 2013, 09:26:23 AM
i am looking for buying/sellinge moneypaks. interested people reply me asap

Moneypak are sold only in the U.S., so I am curious why you would post this in the India forum board.

Also, I just wanted to put out the caution to anyone unaware that moneypak are not like cash, the funds could be reversed if the original buyer who has the receipt claims that the code was lost or that fraud occurred.     When buying bitcoins and paying with a moneypak, consider escrow, especially if the seller does not have a trust history.

Whats the next step from here?

Well, bitcoin transactions are non-repudiable.  You cannot cancel, and you cannot reverse.  So you wait.

If they are not confirming simply because of no-fee, that problem should resolve itself in a matter of hours.   If they are "spam-like" it could take a day, or maybe a tiny bit longer. 

If they are not confirming because they have been double spent (and blockchain.info will detect this and warn you of this having occurred), then you have a different problem with resolution that will vary based on which client you are using.

It has been a while since your initial report.  Does the transaction(s) still show as being unconfirmed?

where does my Bitcoin client download the public keys of others?
Keep in mind that the bitcoin client doesn't know the public key of others until there is a transaction with a payment to from that address.  
FTFY

Huh?

You can't send a payment to an address without the bitcoin network then becoming aware of that address the payment is sent to.  As soon as that transaction is broadcast then each node becomes aware of the address if it hadn't known of it previously.

I'm waiting for somebody to make a bitcoin bot for twitter and facebook like NerFighterSean did for reddit.

Doesn't BTCTip.com do that?   For example, After registering with BTCTip, send a tweet with the following:
 
  Thanks for your help! #btctip @exampleuser 50 millibits!

There was someone doing this on Facebook, Bitcoin-App.com, but that closed recently. 
2165  Bitcoin / Meetups / Re: SoCAL BITCOINERS Poll: Where to meet??? on: February 15, 2013, 02:02:38 AM
Sorry I missed all these meets, was busy having babies (rather the wife was).  Anything planned in the near future?

I'm right next to the LA/OC border.

I'm thinking a bar crawl approach would be great to try.

Find an entertainment district (i.e., multiple restaurants / bars close together).  In the group, one person acts as the exchange.  So the order is taken, people pay the exchanger in bitcoins (e.g, via mobile, or some paper bitcoins even) and the exchanger pays cash to the bar.   Bring some tablet mobiles and [at locations where wi-fi is available] play bitZino, KingCo.in or SatoshiDICE to help show the server / bartender / bar owner one way that some people come into having a bunch of bitcoins they would like to spend on food and drinks.  

Maybe spending a half hour at each stop the crawl could hit about five places in a few hours.  Updates would be made via Twitter or e-mail or something so that late arrivals would know where to meet.
2166  Bitcoin / Press / Re: 2013-02-15 techcrunch.com - Reddit Starts Accepting Bitcoin for Reddit Gold Purc on: February 15, 2013, 12:42:13 AM
While Reddit isn’t exactly a “mainstream” site yet, it is definitely the most widely used site to start accepting bitcoin that I can think of.

The part of the copy that I don't follow reads:

Quote
As people start using bitcoin on Reddit, they’ll want to take their wallets to other merchants. That build of demand will hopefully break bitcoin into the mainstream.

Are they planning to make Reddit Gold work payments outside of Reddit?
2167  Bitcoin / Project Development / Re: ICBIT Derivatives Market (USD/BTC futures trading) - LIVE on: February 14, 2013, 09:00:53 PM
Yes, today indeed. We'll see ;-)

Would you post the final settlement numbers please?

I see the WTI settle price was something like $97.31 on Nymex, I didn't look up COMEX but I'm assuming they would be within pennies.  So if the CLG3 "last" was 3.8709 BTC, that must mean the Mt. Gox daily weighted average price was somewhere near $25.14 today at 20:00 UTC.


2168  Bitcoin / Bitcoin Technical Support / Re: How long does a sweep of funds take? on: February 14, 2013, 04:32:07 AM
Does anyone know how long it generally takes for BTC to appear in your wallet when Mt Gox is sweeping funds?

You should be able to monitor the "sweep" transaction through Blockchain.info.

If the transaction has six confirmations, then the BTCs should be added to your Mt. Gox account.   If the transaction isn't confirming, then it has nothing to do with Mt. Gox and everything to do with it not having fees paid, or it coming from a transaction which also is waiting on confirmations, etc.

If it is a "spam-like" transaction (e.g., low amount, was paid out recently, like within the past day, etc.) it can be a day or longer before a miner includes it in a block.
2169  Other / Beginners & Help / Re: Best Place for Cash exchange from Bitcoins. HONEST Opinions on: February 14, 2013, 04:03:21 AM
Is there any opinion on which sites have best options for US bitcoin users, whether it is prepaid cards, or WU options.

There's one cash-out method that rocks, but you need Dwolla.  But then you get debit gift cards to things like Chevron, BP, Shell, Home Depot, Walmart, etc. etc., with no premium paid -- not even for shipping.  If interested, send me a PM and I'll forward your info to the appropriate party.

As far as cashing out, I always scratch my head in wonderment when I hear someone whine about there being no way to cash out without paying a fee.   But then I look at LocalBitcoins, and I almost never see anyone selling their bitcoins at market rate.      See, ... if you list your bitcoins at spot market rate, the chances of someone contacting you to buy them ... at market rate, increases.

Don't just assume some buyer is going to list that they want to buy at spot rate.   Everyone is looking for a deal, but if you want to sell your coins, list them on LocalBitcoins, at spot rate (or lower if you need to).   The buyers will come running.   Then let those buyers know you regularly have more coins.   Eventually, you'll no longer have any problem cashing out.
2170  Economy / Speculation / Re: Could a btc exchange stabilize the price if it wanted? on: February 14, 2013, 01:59:56 AM
If a btc exchange was richhhh..... couldn't it stabilize the price of bitcoins by buying some when there is a sudden excess of them on the market and releasing them slowly when there wasn't?

An exchange doesn't exist to speculate, it exists to make money off of those speculating.     I don't want my exchange to be taking the other side of any trades.  An exchange should not be exposed to exchange rate risk, for its customer's sake.

A party with a lot of money could leave funds at an exchange to try to stabilize the exchange rate.   But that's capital intensive, and there are costs to carrying the capital.  [Edit: And why would this "rich party" care to do this?]

The exchange rate had just more than doubled from a few months ago.  This wasn't even a 20% pullback.   Bitcoin used to see that level of volatility every other weekend, so it is just a matter of letting the market discover the price.  Merchants who use a payment processor to convert to cash weren't affected by this.  But obviously a volatile exchange rate isn't good.

When more methods for shorting bitcoins are made available then the exchange rate should level out a bit.  There are a couple that I know of being built or are in limited (invite-only) trial currently.
2171  Other / Beginners & Help / Re: Any way of retrieving BTC from Tradehill? on: February 13, 2013, 11:35:08 PM
I saw an old article today saying they were returning all the funds back to their clients? 

The thread with the e-mail address for you to send your inquiry:

 - http://bitcointalk.org/index.php?topic=101467.0 

Did they perhaps make their clients wallets available on backup servers, and are those perhaps still accessible (30 years later, or whenever Tradehill went down)?

A hosted (shared) EWallet like what Tradehill used does not have the concept of "client's wallets".  Your bitcoins were in Tradehill's wallet.    The problem likely ins't that there is a problem accessing the wallet the problem is that the company claims to have suffered what ended up being fatal losses when Dwolla reversed deposits.  As a result, the company doesn't have all the bitcoins necessary to repay those who had bitcoins deposited.

If I could find my Tradehill wallet backup (which I don't think I can), could I recover the coins? 

So there's no such thing as a "Tradehill wallet backup" that its customers had.

I need a MP to load my pre-paid debit card ASAP so my mother can use it to pay for her doctor's visit expenses today.

We should start thinking like Roger Ver. 

Something along the lines of.

"I see you don't yet accept bitcoin payments.  I prefer to use bitcoins to pay for stuff.   Here's my payment in bitcoins.  [Sends a coinapult e-mail with bitcoins in the amount of the purchase].  We cool?"
2173  Bitcoin / Bitcoin Discussion / Re: Tweet #hashtag to buy -- American Express Launches Purchase by Tweeting on: February 13, 2013, 11:22:24 PM
Twitter and American Express have expanded their Amex Sync partnership to include a purchase-by-hashtag feature. The new service will allow users to buy products promoted on Twitter by tweeting the appropriate hashtag.

Chirpify was the innovator of that.

Ihad suggested how bitcoins could be used in the same manner:

After seeing what Chirpify is doing (providing a way for people with twitter accounts to sell stuff through tweets and then have chirpify take care of collecting the payment), I wonder if there is anything that BTCTip could do along the same lines.

[...]

If the Chirpify concept were driectly adopted, here's what a solicitation might look like::
  "Selling used ATI 5870, for ~$145 worth of bitcoins.  Reply "bitcoinrocks" to buy for 29 BTC via @BTCTip http://pic.twitter.com/xxxxxx"

But I think Twitter's new terms of service make this approach to be pretty much a dead-end unless the service has officially partnered with Twitter.

where does my Bitcoin client download the public keys of others?

Keep in mind that the bitcoin client doesn't know the public key [Edit: Bitcoin address] of others until there is a transaction with a payment to that address.  

For example, create an address using BitAddress:
 - http://www.BitAddress.org

That can be created offline (e.g., load the page, disconnect from the internet, then generate a new one).  That is a valid address but nobody else in the world knows about it.   You can give that address to anyone and they can send bitcoins to that address without the network ever having seen it before.

You could hit print and leave the computer disconnected for 50 years, and the funds would still be there waiting to be spent (by someone with that private key).
2176  Bitcoin / Hardware / Re: A letter from Avalon on: February 13, 2013, 11:42:55 AM
if I send bitcoins, how do I prove that these bitcoins came from me?

If you sent from Bitcoin-Qt (or any other client in which you have the private key, ... such as MultiBit, Electrum, or Blockchain.info/wallet) you can use the Bitcoin-Qt client to digitally sign a message to prove ownership as nobody could do that except someone with the private key for that address.

If you sent from a hosted (shared) E-Wallet, such as from Mt. Gox, Instawallet, Coinbase, Paytunia, etc, then you are pretty much out of luck as far as being able to prove that the payment came from you.

How to prove that the sender for a payment was truly me?

2177  Bitcoin / Bitcoin Technical Support / Re: deposited to my address, cant find the transaction on blockchain, how is that? on: February 13, 2013, 11:33:15 AM
Hey guys, Is there a way how to hide a transactions done on the network? Because i wanted to register on one site that has an activation fee paid in BTC. I obtained BTC address when i created my account there and it clearly says i deposited 1 BTC and that BTC was later taken from me, so my account would be activated. Now this is OK, no problem there, i got activated. My question is, i checked blockchain/blockexplorer for the address i used and it says that this address was probably never used on the network, how is that possible? is there some way how to hide transactions? Im a bit confused.

the address stayed the same the whole time.. why would it change, right? yet no transactions show to or from on the network for that address. the balance in my account for that address showed 1BTC, now its zero. there is no way i can check where that 1BTC went from my address (not that i care) and it wont even show on the blockchain/blockexplorer from what address I initially received that 1BTC (i have sent it to myself obviously). and here i thought the network is open.

If you are paying from a hosted (shared) E-Wallet to an address for another party using the same E-Wallet provider then depending on how that provider operates, that transaction might end up just being an account-to-account transfer that is internal and never touches the blockchain.   Mt. Gox is one such provider that does this.  Mt. Gox also happens to offer an option when withdrawing called "Open Transaction".  When this checkbox is marked, the transaction will always go through the blockchain, regardless of whether or not the recipient is another Mt. Gox user.   This causes the payment to not be instant, however, and it must confirm before the recipient gets the funds.

2179  Other / Beginners & Help / Re: How to buy large volumes of Bitcoins anonymously? on: February 13, 2013, 10:09:20 AM
There's always the in-person cash-exchange, but what about nice, convenient online options?

Somehow the cash needs to transfer, and there are almost no "anonymous" methods for larger amounts.  For instance, BitInstant has limits of $500 USD per transactions and $2,000 USD per day.

There are a handful of bulk sellers (Tangible Cryptography and BitPay being two) but they require a bank transfer or other method in which wouldn't be considered "anonymous". 

Occasionally there are larger amounts of bitcoins being shopped OTC (over-the-counter), and usually indirectly by a party claiming to serve as the intermediary.  I've seen these communicated on the #bitcoin-otc channel, the #bitcoin-assets channel, on private Skype chat rooms, and through personal messages sent on the forum.   

Also, every merchant that accepts bitcoins is a potential source for coins.  For cash-flow purposes some of these merchants occasionally need a local buyer for large deals where a customer pays with bitcoins.   The merchant might not be selling the coins directly to the anonymous buyer but a broker acting as intermediary might.

Anybody know of any projects already working on this?

LocalBitcoins today has a fairly comprehensive directory of those who buy and/or sell bitcoins for cash.  Some of those listings show "max trade" amounts in the thousands of dollars range.  Even traders who don't directly offer larger amounts might know how to facilitate a larger trade (by partnering with other local traders, or by brokering a larger deal).

To-date, I don't really know how much interest there really is in acquiring large amounts of bitcoins anonymously.  I do believe there is a bigger (and growing) interest in finding ways to anonymously convert bitcoins already earned or otherwise acquired into other forms of value.

So I suspect anyone with cash will easily be able to find an anonymous trade, but the reverse -- someone with bitcoins will have a little bigger challenge in converting those coins anonymously to cash.      When there is the volume to support it, a service that maintains an order book for local traders will probably be needed such that less and less needs to travel through the exchanges.  Ripple could become a tool used here as well.
