Are there any wallet that stands out from a security perspective? Here's the list of eWallet providers. - http://en.bitcoin.it/wiki/Category:EWalletsMost exchanges can be used as EWallets, though there are reasons why not to do so. Those with multi-factor authentication (e.g., Mt. Gox's YubiKey, TradeHill's DuoSecurity and Camp BX's SMS Text) would be among the most secure against identity theft. One EWallet WalletBit uses what they describe as "secure card" as the method to help prevent unauthorized spend transactions. - http://en.bitcoin.it/wiki/WalletBit |

What are your favorite articles that either got you into Bitcoin, or that help you advocate The Bits and Bob article in the Economist is by far the best article from the press so far. For a technical description the omega tau podcast is well worth the hour and a half of time. Both can be found on the Press page on the Bitcoin wiki: - http://en.bitcoin.it/wiki/Press |

What mean this? Because every transaction since the dawn of Bitcoin time (Jan 2009) are stored on every node, there is a network and storage cost for each transaction. By imposing a fee, fewer "spam"-like transactions will be sent. The current version of the client will ask for a fee if the transaction has certain characteristics. 0.0005 BTC is about a third of a penny, at current exchange rates. PayPal, for comparison, charges a minimum of $0.30 per transaction for commercial purchases. - http://en.bitcoin.it/wiki/Transaction_fees |

I'm not sure where I happened across this, ... I use it as the wallpaper on my phone. If there were a desktop size version, you might find interest.  |

No. Most countries ARE on 240 volts  Never seen 120 volts outside the US (note: I was not everywhere on this planet). U.S. and Canada. and from Mexico to much of Brazil all are. - http://www.kropla.com/electric2.htm |

They have more non Bitcoin related transfers now though. They seem to be growing fast, Dwolla's model makes sense. $0.25 for a $100 transfer is much less than the $3.20 that PayPal charges. I've already had it happen where someone I've sent money to previously has now asked for the payment to be sent with Dwolla instead (to minimize the transaction costs). Of course,Bitcoin was the only reason that person had already signed up with Dwolla but kudos to Dwolla for being in the right place at the right time. One of the worries that I had was that if Bitcoin were to start to take market share from the payment networks, would they simply lower their fees to lessen the cost advantage that Bitcoin offers? Then I realized that Dwolla can actually take away some of the profitable business away from Visa/MC. The remaining business for Visa/MC will be the more problematic, less profitable transactions (merchants with a higher rate of chargebacks, customers who are paying with credit because they don't have the cash and thus might default at higher rates, etc.) So Dwolla succeeding fantastically at the expense of the legacy payment networks will actually be something to look foward to. Going from one payment method (payment card only) to two methods (payment card or Dwolla) is much harder than going from two methods to three (payment card or Dwolla or Bitcoin). Dwolla can do a little trail blazing for Bitcoin. |

2) After discovering the first theft, I changed all passwords and PINs to do with LR, and I did not leave them anywhere. I never used my keyboard to type them out so a key logger could not have got it. From the hindsight is 20/20 department: If you had discovered that some unauthorized access (particularly theft) had occurred, your mindset should have switched to assuming that you have a compromised system. Then with that assumption you then work towards regaining a secure environment before doing anything else from that point on. After I was initially thinking that Liberty Reserve's on-screen keypad and other security measures were pretty decent, I then learned how they were all easily circumvented by a skilled attacker. See for more info: - http://bitcointalk.org/index.php?topic=2574.0It is unfortunate that Liberty Reserve does not employ a multi-factor authentication such as those in use by Mt. Gox (YubiKey), TradeHill (DuoSecurity), Camp BX (SMS Text Message), and others. If they had, you would likely still have your LR funds. Now, going forward, you still probably want to assume that your system has been compromised and has been in that compromised state for at least a week now. I'm not a security professional though. Perhaps someone else here can recommend how best to proceed from here. |

What they are proporting to have happened has nothing to do with a 'double spend' as it would refer to spending the coins immediatly from the account to elsewhere before the site could see that no deposit showed up in the blockchain. A post by Theymos on July 1st, in another MyBitcoin thread: MyBitcoin is still accepting payments with only 1 confirmation. This is insane for a bank. Any miner capable of mining two blocks in a row can steal money from MyBitcoin pretty easily. I'm surprised no one has attempted it yet. - http://bitcointalk.org/index.php?topic=22221.msg309173#msg309173 |
