So I was inspired by the legend Andreas M anotopotoolousposuts to flip a coin 256 times and generate my own private key. I will use this as my cold storage.
How do I then hash the 256 bits of data into a private and then public key? Is it possible to do the maths without a computer at all? If not, is there some code I can run on an offline computer?
Thanks
1. using a computer 2. no 3. bitaddress.org brainwallet tab should be the simplest. |

The wallet file is not empty and you still have the blockchain_headers and config files. Delete blockchain_headers and config files and run electrum. If it still doesn't start up then open up the default_wallet file in notepad and see if you can see the seed that dabura667 was talking about before. Notepad is a text editor while wordpad is a word processor. I think you'll have better luck with notepad. I wasn't clear, I deleted those files and tried to run electrum. It didn't work then I moved them back to try something else. I've opened the deafault_wallet with Notepad (not wordpad) as suggested twice now and it comes up empty. According to the screenshot you posted the default_wallet file is over 100KB in size. So how can it be empty? |

If you don't have another wallet file in that folder then the only option is to look at backups. Do you have backups? Another thing you can try is Windows system restore to restore to an earlier time.

Another one? I get the feeling we have an epidemic or something  Don't bother reinstalling. That won't change anything. Find your electrum folder and delete the files named 'config' and 'blockchain_headers'. Location of the folder: https://en.bitcoin.it/wiki/Electrum#Wallet_FileSee if electrum runs now. If it doesn't then you'll have to restore from seed. The way to do that is to rename the electrum folder to something else and run electrum. Select restore from seed and go from there. Also before asking any more questions tell us your electrum version and operating system. |

She is welcome to host only straight weddings. The issue is that she wants to have a business that won't serve gay people. How bout a an ice cream stand that is for whites only, or a hospital with a sign that says "no Muslims".
A hospital that says 'no muslims' or 'no blacks' is better than one that welcomes people in but then drugs them with contraceptives without their knowledge: http://www.theguardian.com/world/2013/feb/28/ethiopian-women-given-contraceptives-israel |

What other files have you got in the electrum folder? Give us a list of files and folders or post a screenshot. For the record electrum folder is \Users\YourUserName\AppData\Roaming\Local\Electrum
Also do you have a copy of that folder or your wallet backed up somewhere?

5GB is a weird memory amount. I assume it is 1GB DIMM and 4GB DIMM. I would either add a 4GB DIMM (8GB total) or remove both and add a pair of 8GB DIMMS (16GB total). Save the rest of your funds towards an SSD.
You're right, it's a combination of a 1 GB DIMM and a 4 GB DIMM. The computer originally had 2 GB of RAM but I had the store I bought it from swap out one of the 1 GB for a 4 GB since 2 GB of RAM just doesn't cut it in Windows. So do you think the 20 GB of RAM I was aiming to upgrade to is overkill? Upgrade to 8GB. It should be more than enough. But first check your hard disk. Run chkdsk/scan disk or whatever you have on windows. Do the long test - the one that takes hours  edit: it's chkdsk /r |

I've tried a couple of methods detailed in some other threads but in case I did them incorrectly I'd like to proceed as if I haven't.
How about telling us what you've tried so we don't waste time repeating ourselves? It's very hard to mess up finding a folder and deleting one file in it. |

I read the title and I thought you enlisted. The bitcoin foundation should start financing a bitcoin army. Perhaps you can bring it up at your next meeting? That's a good idea. Currently we farm it out to Al-Qaeda.  I would have guessed IDF considering you have Ploshay on board |

I installed Armory, created a cold storage wallet and printed 2 paper wallet copies. I also backed up an encrypted digital copy that's on 2 USB's and in a password protected WinRAR file on my Google Drive that has 2step. I exported the watching only copy to my desktop and deleted my cold storage wallet and imported the watch only wallet. Do I just send coins to my watch only addresses and they will be there in my wallet?
That's no longer a cold storage wallet since you stuck it up on google drive. Cold storage means it never goes online. Actually cold storage means paper wallet which is not what you are trying to do. Offline wallet is the correct term. Apart from the above, I would never be happy with an offline wallet until I had first sent a small amount of btc there and then made sure I could spend it. Yeah, I was kinda iffy on putting it there, I ended up deleting it off drive. Is it good now? I have a watch only copy on my online computer. It's no longer a strictly offline wallet. If you want one of those you should create a new wallet in offline armory. |

Should I be concerned at all about transaction costs? I anticipate most deposits will be around 0.01~ BTC but there will be the occasional withdrawal of 3BTC~. Is there a best practice for keeping transaction costs down?
There is but it only works for sites which have a large volume of transactions. Sites like exchanges. What they do is they send withdrawals out in batches i.e. in large transactions. This saves them some fees but it means that people have to wait a few hours for their withdrawal to be processed. |

The deposits all get left in the unique addresses. So now I'm writing code to allow people to withdraw money and unless their wallet has enough funds then I need to somehow pull funds from multiple of the unique deposit addresses. This doesn't make sense. You want to allow people to withdraw more than they deposited? I don't think that's what you mean. I think you are worried about how bitcoind will fund withdrawals. Bitcoind will automatically grab coins from whatever outputs there are to fund any withdrawals. It will not limit itself to certain addresses. You will need to track how much a person has deposited, how much they've spent and how much they can withdraw. Also avoid the bitcoind "accounts" feature. That's just crap. |

You should write down what you remember of the password immediately. Then try as many variations as you can. Maybe do this in a few sittings because sometimes a fresh mind can work magic. If you still can't decrypt the wallet then your best bet is to contact this guy: https://bitcointalk.org/index.php?topic=240779.0 |

It has happened before during periods of big and frequent buy orders, I don't think there's a reason to worry. It may be because of this period of vacations by the way.
What vacations? |

Sorry for not explaining myself that thorough. I've bought a bunch of bitcoins at different prices in a span of i dunno.... about 2 years and I've lost track if i'm in the black or the red.... So in essence what I'm asking is if there is a program where i can take all of my bitcoin buys and sells and it could tell me if i'm ahead or if i'm down in profits.... I feel so stupid because I lost track and everything :;sighs::
Yes. It's called a "spreadsheet" |
