Posting this for record purpose. 0.59 BTC will be sold to Abdussamad using Escrow service of MaidakI have agreed to the These terms.
First we should come to an agreement. The price for instance. You rejected the earlier price by email so the current price is Rs. 56,388.
If there are any escrow agent or bank fees you have to bear them. I will make a cash deposit in your bank account. This is where I physically go to a nearby branch of your bank and make a deposit into your account.
Payment will be made within 2 working days. Because we are using an escrow agent I request an additional working day as a grace period. A working day is a day on which the bank is open for business in Karachi, Pakistan. Banks are usually open 9AM-5PM Monday to Friday. If there is a strike or other disturbance that causes the bank to not open on a particular day then that day will not count as a working day.
In case of a dispute I will provide a scanned copy of the deposit slip as proof of payment. In case your account is with UBL the deposit slip may be a computer generated one printed using a thermal printer. Otherwise most banks' deposit slips are manually filled out and carry the teller's stamp.
In case of a dispute you must provide a scanned copy of your bank account statement. This cannot be an electronic statement but a scanned copy of a hard copy statement printed on a paper that carries the bank's letter head.
Do you agree with the above?
Agreed. Please note the price above is for a whole bitcoin. 0.59 btc will be Rs. 33,269.00 less escrow and bank fees. |

ok, I typed getseed() in the console and definitely mistyped the seed .....
So what to do now to get the proper seed in?
I tried deseed() but it doesn't seem to have done anything, when I type getseed() i still get the incorrect seed, hence new wallet instead of importing my real one.
I am assuming all of this is on the new machine? If yes then simply delete the wallet file and restore from seed again. You can find the wallet file in the electrum directory: https://en.bitcoin.it/wiki/Electrum#Wallet_File |

But make multiple backups and if you encrypt them as well (with TrueCrypt, PGP, etc), then you can even upload some to the cloud. But put one on a flash drive and mail to a relative or bury it in the yard or whatever. As long as it is encrypted, and you can decrypt it, then it shoudl be safe.
Removable drives are ok but online accounts get hacked all the time and are not safe. If you store it on a removable drive the thief has to a) get the drive b) brute force the password. If you put it online then getting the wallet file becomes that much easier. Your wallet then becomes a brain wallet with a human generated passphrase. If you set a good enough password, it isn't going to be "brute forced". Mine is a fairly long nonsensical sentence with extra characters and numbers, etc. And remember you would have both a password on the Multibit wallet itself and and also on the file encryption, so that is two they have to break into...and PGP hasn't been broken yet and neither has TrueCrypt to the best of my knowledge. If you upload it to the cloud, I would zip all of it into one file and encrypt that...change the name to ___.avi or .jpg or whatever and then people wouldn't even know it is a bitcoin related file. See here on why human generated passphrases or passwords are no match for brute forcing: https://bitcointalk.org/index.php?topic=311000.msg3345309#msg3345309 |

Can you expand on what you are looking for? I am bit confused. You talk about cold storage and disks and at the same time your own wallet? Generally speaking live cds tend to be write only so, while you can have one that comes with electrum, you won't be able to save your wallet file there. Also saving your wallet on the disc means that you will have something you will use across sessions and that kinda defeats the purpose of using a live cd in the first place.
Maybe I'm just over thinking it.
BTW electrum can be used for offline wallets. In that scenario you are saving the wallet on a dedicated offline PC. It can also be used to create brain/paper wallets using a live cd in which case no soft copies are saved and you just recreate the wallet from seed everytime you want to use it. So which way are you leaning?

You can use the label sync plugin to sync labels across machines.

I'v seen a website recently that claims to crack private keys only if you remember at least some part of the key, as you do the website might be just for you I can't remember its name so try browsing around the forum a bit for it  Maybe there's a website that will crack a website url that you can only remember a part of  LOL google |

I double checked and I definitely created the wallet on Chrome. It's strange because I wrote the password down twice with details to remember. I've been trying a bunch of variation but I'm stumped
Bitaddress is under active development so maybe something changed in the current version that is affecting wallets created using an older version. First you should look at your browser history and note down the full URL and date on which you created the wallet. Then see if you can get the private key to decrypt using an older version from their github repo |

Thanks guys
Thing is how do you change it for every transaction? If a site is paying you a few times a week say... You have logged an address just for that site. How would you change it for each tx? Keep going back to the site daily and entering in a new address? Impossible to do it you had many of these sites paying you?
In such a situation you don't change the address. Simples. In future we might see solutions to these scenarios as well. There are three competing implementations that I know of: 1. Deterministic wallets. You submit the master public key of a branch and a the site generates a new address for each transaction using that. 2. Bitcoin payments protocol. 3. Stealth addresses. Only time will tell which one of these gets the widest adoption. |

Did you try echoing the last line: echo $bitcoin->getinfo();

How do I secure my Bitcoin then Abdussmad....
It's a gradual process. You learn bit by bit. Here are two options for you: 1) Continue down the paper wallet route. I don't recommend paper wallets but if you are careful you can do cold storage this way. You should start by trying to spend the 0.001 that you've sent to the paper wallet. Then when you're done that successfully you create a new paper wallet, load a small amount into it and spend from that one. Do this in increasing amounts until you become confident. The sweep key approach in blockchain.info is fine. But you should read about change addresses as well: https://en.bitcoin.it/wiki/ChangeWhen you spend less than the total amount in an address some of it is sent back as change to another address. This is why you sweep the private key and not import it. 2) Use a bitcoin client that is designed for offline use. This will require a dedicated PC. There are two bitcoin clients that currently support offline wallets - Electrum and Armory. I recommend electrum. Install it on your online computer, play around with it and see how it works. Then, once you've got the hang of it, you can try for an offline install. |

Having a nervous breakdown here...
Then stop trying to do what you are doing. The way you are going about it you are likely to loose bitcoins because you made a mistake and not because somebody stole them from you. |

In the worst case scenario what will happen to my bitcoins if my computer is damaged. If I have a backup of my key saved on a usb ; will I be able to buy another computer, download multibit and then upload my previous key? This is my understanding and everything will be normal right?
Yes. Are there any risks or things I am not considering?
Thank you
The biggest risk is that you don't have a complete backup. A complete backup is a recent backup that contains the private keys for all your addresses. If, since your last backup, you created a new address and received coins there then your backup is stale and you need to create a fresh backup. To prevent problems arising from a bad backup you should practice restoring from backup. |

The Magic the Gathering clowns best hope it's the U.S. that takes more interest in prosecuting him. The Japanese legal system is notoriously slow and inefficient, and it is not unheard of for a case to take five years or more from charges to trial. I think anyone associated with Gox would also be considered a flight risk.
They also have a higher conviction rate and far less crime than the US. I hear that even the mobsters (yakuza) there are afraid of carrying guns. |

Good point about Bitpay actually slowly cashing the coins as opposed to the three big retail outfits. If I were them I would actually keep the bitcoins for a few years or offer them as bonus to workers if they volenteered.
I am sure they have a reserve of coins and USD. But, speculating on the value of bitcoin is not a good idea for them. Their specialization is processing bitcoin transactions for merchants. That is their story. It is what they tell their shareholders, employees and customers. If they start doing something else then they become something else entirely. You pick a way of making money and you stick to it. |

if electrum private keys can be restored using 12 dictionary words for the seed, isn't that less secure?
No, but I understand where this is coming from. This was one of the first questions I asked about Electrum too: https://bitcointalk.org/index.php?topic=153990.msg1883397#msg1883397The seed is a 128bit random number generated by a computer. Computers are better at generating random numbers than human beings. The seed in words is merely a human friendly representation of the numerical seed. Changing the way it is presented does not change the fact that it has 128bits of entropy. Edit: Also if you want to know why human generated passphrases are a bad idea see this post from a bitcoin-qt developer: https://bitcointalk.org/index.php?topic=311000.msg3345309#msg3345309 |

even if it is over 60 alphanumeric + symbols long with none of it being from a dictionary?
A real private key is only 51 characters, just use that. easier for me to remember if i get to make it up  That right there is the problem. If you made it up then it doesn't matter how long it is it is not random enough to be a secure passphrase. My suggestion to you is that you install electrum on your offline PC. It can function both as a brain wallet and a full fledged offline wallet. |

if you whant to buy with bitcoins you need to buy them first...
The general idea behind what the op is saying is correct. It's just that he doesn't understand the details. This is my opinion: - No new users are buying bitcoins to spend on these merchants. It is too hard and costs too much to do that. CCs and paypal are much more convenient. - Instead it is long time bitcoin holders that are bringing coins out of cold storage and spending them. Previously they had no outlet to spend their coins. Now they do. - This increases the supply of bitcoins in circulation pushing down the price. Also as far as the details goes it is bitpay and coinbase that are selling these coins not the merchants themselves. The merchants only take USD. |
