So what will it be?   Save 3% by paying with bitcoin, or would you rather "pay with your face?"

You are in Dwolla country.  Maybe you could find someone who would cash out your Dwolla to fiat?   CampBX allows Dwolla withdrawal, for instance.

I reinstalled it on another computer and replaced the wallet.dat with the backup. It seems to be working fine so far. Is that good or no? I had no idea it would take so long to download

Yes, it will take several hours at least to download the blockchain.  Hope it solves your problem!

By the way this is my favorite bitcoin website.

It really is a fantastic service, isn't it?


I hope it gets more and more popular so the pots get larger.

Though I make mostly small wagers, I have many of them open currently.   Instead of withdrawing winnings though, I find myself using those towards additional wagers.  And because there are many new bets all the time, I am depositing more pretty regularly, so my "Balance in Bets" keeps growing:
 - http://betsofbitco.in/profile

I wonder if that is typical use.

UPDATE:  I have looked a little closer and found that the unrewarded wagers are real.  It's likely that many of them are simply wagers that will be returned/rewarded, but hadn't made it into the blockchain yet, as of the moment my script was run.  However there are definitely some that are more than one day old, which suggests that a small fraction of bets are not being returned, at least not in a timely manner.

Hadn't you found that those have since been resolved?

was going to withdraw with dwolla anyway, but this 'withdrawal center' thing has been pending verification of my dwolla account (I guess??) for the last 12 hours or so

Mt. Gox has been indicating that it is taking several days (up to 6) before they can send the Dwolla funds.  You can request from Mt. Gox that they cancel the transfer, however.

When it is encrypted it is all binary and not easily editable outside of the client.
But once it's encrypted I can't get the text version back again (by say "decrypting" it permanently)

I see.  There is not yet the feature to let you revert a wallet back to being unencrypted.

There is, however, an easy way to access the contents of the wallet using RPC.

Edit your bitcoin.conf  to put in rpcuser and rpcpassword entries.

 - https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File

Run bitcoin as a server, e.g.,

$ ./bitcoin-qt -server

then

Open it for RPC

$ ./bitcoind walletpassphrase [passphrase] 1000

then you can

$ ./bitcoind dumpprivkey [bitcoin address]

or

$ ./bitcoind importprivkey [bitcoin address] [label]

 - http://en.bitcoin.it/wiki/Importprivkey


Does that help?

p.s., Editing wallet.dat with a text editor is a bad, bad idea.
6328  Other / Beginners & Help / Re: Bitcoin transmission in limbo on: May 17, 2012, 03:42:16 AM
the program crashed and can't be reinstalled.

Step 1.) Create a backup of your existing wallet.dat

That wallet.dat can be used on any computer to recover.  

If you want to try getting that specific installation back to being operational, remove all data files except for wallet.dat and then launch Bitcoin again.

Please consider reading this thread:

I got suspended for selling paperclips with free bitcoins 2 days ago, and yes i sent the damn clips with a tracking number. They want all kind of documents to re-enable my account. I had only positive votes with them but the fees are killing me so i think i will pass doing something about it. They will get to know bitcoin in the end.

My understanding is that Paypal is not accepted as payment for a virtual currency, mainly because of reversals but partially as it is against their policy.

How does Virwox get away with using paypal as a payment gateway for Linden dollars then?

Discussed here:
 - http://bitcointalk.org/index.php?topic=77777.msg865818#msg865818


Also, how long after a transaction is complete, does it take for a payment to become non-reversible?

Well, the generally accepted answer to that is six confirmations  Each service can set it themselves.  Most exchanges require six confirmations for bitcoin transfers, for instance.   CoinDL, a digital download service, accepts payment immediately (on 0/unconfirmed).  Others may give credit after two or three blocks, as the benefit to an attacker for that particular business (e.g., goods get shipped out to a physical mailing address) causes the transaction to be low risk.

0/unconfirmed can be sufficient for low value or high margin sales when 1.) the client does not accept inbound connections and 2.) the client explicitly connects to well-connected nodes.  That is still vulnerable to a Finney attack though, so waiting for 1 confirmation lessens the risk of a double spend.

So it really depends on what type of transaction it is, and thus is there a reason to worry that an attacker would attempt to double spend on you.

So, I'm gathering from my surfing that it isn't easy to manipulate a wallet outside of the bitcoin client once it is encrypted.  And once it's encrypted it can't be easily decrypted.  Is this accurate as far as you know?

Well, the wallet itself isn't encrypted but the private keys needed for spending from the wallet are encrypted.  If you used a strong passphrase for that encryption, then your wallet.dat is useless to anyone except those who know your passphrase.  The client asks for this passphrase each time you either create a new address or make a spend transaction.

Of course, a compromised system could have a keylogger or other type of malware on it in which even a strong passphrase doesn't protect you.   So for amounts where greater security is warranted, there are things like "air-gapped" offline wallets (cold storage) and other approaches that can greatly help improve security.

Is the .099 BTC part of the transaction the "transaction fee" that goes to the miner who correctly hashed my transaction onto the chain?

Nope, there was no fee paid on that transaction (which explains why now several hours later it still has no confirmations).  It will eventually get included in a block, maybe another 24 hours though.

As far as what that 0.099 BTC is about, ... that is the change transaction that goes back to your wallet.   When you made the SatoshiDICE wager for 0.001 BTC, the "best" coin for that was your Deeptbit payout (1VayNert3x1KzbpzMGt2qdqrAThiRovi8) coin, which you received 0.1 BTC.  Because bitcoin transactions spend the entire INPUT, what it did was created two outputs.  One to SatoshiDICE for 0.001 BTC and one for 0.099 which is to a new address in your own wallet.

The Bitcoin client takes care of everything out of sight to handle this so users don't need to know what adresses are in the wallet.

I didn't know that the client retransmitted the transaction.

Looks like it just made it to the blockchain:

I have an unaccepted transaction in my wallet.
My wallet is encrypted.
Is there a way that I can resubmit the transaction or decrypt my wallet so that I can edit out the transaction?

Are you saying it is a spend transaction that should be valid but that it hasn't been included in a block yet (such as the fee not being high enough)?   Or are you saying it could be a double spend (e.g., what could happen when using multiple copies of the same wallet.dat) and thus the transaction will never confirm and is a cosmetic nuisance/

If the former, does the transaction appear in the blockchain, even as unconfirmed?
 - http://www.blockchain.com

If not, have you given the client time to rebroadcast the transaction?  (i..e, leave it running for an hour or so)?
6336  Economy / Speculation / Re: Any evidence of a correlation of BTC to any other asset? on: May 16, 2012, 09:04:16 PM
Just curious what everybody's thoughts were.

It seems to me that BTC is just so tiny it's hard to draw any parallels with anything else.  I mean, there's more traded in AAPL in 3 minutes than what the entire BTC economy is worth.

There are parallels to things like Google Trends, but of course, that's not another commodity or asset class.

You might find this thread interesting.

I see using the "Services" link in the top right gives the ability to switch between feeds.

The when in 'ticker" view, it shows "Order Book" only (which is the Mt. Gox book).

I can not get a refund from Getbitcoin.com  They took my order and my money but did not fill the order.  When I asked about it it took several days and then Tom said that they no longer take ACH orders from banks and that the money was refunded to Chase Quick pay.  I can not get it back from Chase or Get Bitcoin.  Anyone else having this issue?

They haven't dealt with ACH for a long time, as far as I know.  When did this occur?

Get-Bitcoin should be able to give you a reference (Bank ABA, Account number and Date submitted) for the ACH transaction where the funds were returned.  Chase should then be able to tell you where those funds are then.

Crapachino.  I just $995 from MtGox to my Dwolla account on 5/15 and it's not showing up on Dwolla.  Oh someone's going to get an earful.

Mt. Gox has acknowledged that their delay in sending it to you through Dwolla is currently around six days.   Once it reaches Dwolla it is instantaneous.  You can place a request with Mt. Gox to cancel the withdrawal instead.
