It isn't finished (yet), i just had 10 minutes over my lunchbreak, so i made a first "draft".. No checking for correct keys ATM. Just enter the characters that can be used to insert into your key in the $db string, and the key (missing 1 character) in the $privatekey_wif string, and the script will generate all possible combinations... It should run on windows  with activestate perl, without any extra modules... It's untested, and i don't take any blame if things go wrong  You can take this script, and invoke any windows command (like bitcoin-cli importprivkey $key) and make this work, or you can wait untill i've included a checking-function (if and when i find the time to do this). #!c:\perl64\bin\perl.exe
$db = "allvalidcharacters";
$privatekey_wif="mykeymissingonecharacter";
@delen = split('',$privatekey_wif);
@letters = split('',$db);
$length = length($privatekey_wif);
for ($position = 0; $position < $length+1; $position++)
{
foreach(@letters)
{
@new = @delen;
splice(@new, $position, 0, $_);
print join('',@new)."\n";
}
}

Thanks mocacinno for quick reply. Well if users would not be able to restore wallet without seed creation time, then how other wallet apps like Electrum or Multibit are restoring wallets of their users because i can see only seed word of my wallet in these wallet apps and if i need to restore my wallet, it just asks me to enter seed words but not seed creation time.
Further I want to ask one more question. While restoring wallet, should i delete wallet and block chain files both and re-create them or just one them should be deleted and if so then which one. Actually I am beginner to bitcoin and just confused how to deal with wallet and block chain files while performing restoring operation. Your help would be much appreciated.
Disclaimer: the next explanation was given by me... I have a lot of experience writing php/mysql scripts, enough experience using bitcoin and loads of experience in database management. I did not, however, use bitcoinj to write my own apps, neither did i ever read the full electrum sourcecode. My explanation might be off at times, if a more senior and experienced member finds any flaws in my logic, he's free to say so  Bitcoinj is a java library intended to create wallet apps. As far as i know (read the disclaimer!!!), bitcoinj is not a fully implemented deterministic wallet* (like electrum and multibit). If you want to create a deterministic wallet using bitcoinj, you can do so (if you wish), but the deterministic part of the wallet will have to be coded by you (or you can possibly use other librarys to do so). When you started your OP, you said you were writing a wallet app using bitcoinj, and that next to the seed words, the seed creation time was needed, so i assumed you were building your own kind of deterministic wallet using seed words plus a timestamp. As far as i know, electrum doesn't need a timestamp in order to create their private keys. * https://en.bitcoin.it/wiki/Deterministic_wallet |

Hi,
I am creating a wallet app. After wallet creation user can see his wallet words. While restoring wallet from seed words, seed creation time is also required. So my question is do i need to show seed creation time along with seed words? so that user can record both seed words and time and when restoring required, user can provide both of them.
If you need the seed creation time AND the seed words in order to restore a wallet, it would be wise to show both indeed... Otherwise your users won't be able to restore their wallets (if i understand correctly). |

I'm still waiting on the OP's plans for other countrys.
I do hope it's cheaper than the spanish plan: 6€/SMS gets you 0.005BTC -> but at preev rate this equals ~1.9€.
I like the concept, but the prices need to be better in order for this to succeed, 300% markup is a bit to much IMHO

What if I have a free SMS plan ? Like right now I get to use 20 SMS daily free of cost.So I should get free satoshi's or you have your own sms service provider wherein my regular sms plan costs are not applied ?
I don't know how the OP's system will work exactly, but i do know a lot of those free SMS plans will still bill you for premium SMS's... I guess it'll depend on your specific contract. |

Hello, I wanna introduce to you SatoshiSMS ( https://satoshisms.com). What is this?, We're going to sell BTC using SMS Premium as the only payment method. We're on a validation proccess with a great SMS gateway provider. If you wanna know how much you get for a SMS just send me your country and your mobile service provider. Real example: Country: Spain, 1 SMS, you pay 6€, you get 500.000 satoshis. I know it's gonna be really useful for those people which have a lot of SMS credit but lost it all because they didn't spend it. Instead of letting your operator take away your money every month you can use our website and get some bits to gamble, invest, save, whatever you want... If you would like to invest with us or ask any doubt, send me a PM. Have a nice day . Sounds like a good idear... I'll keep an eye on your thread, and would like to see some rates for my surrounding country's (because i know several people in the surrounding countrys) The Netherlands Germany Belgium France ... |

@deepceleron: thanks for the info, i never tought about the problem like that.
Since it seems to be an interesting problem, i'll try to write a perl script to take a private key in WIF format with x missing letters as input, and permutate all allowed characters in this string, test if the permutated pk is valid and write all the valid keys to a logfile (or import them in bitcoin core directly).
Since this is a bit more difficult, and i can only work on the problem during my luchbreak, it might take a couple of days tough.

yeah altcoin xvg, When I make a deposit Wallet status : Online after one day then they pretend to make it a status Wallet : Maintenance . odd they did not give any response . This is a fraud !
OK, so now we have a clear picture: you deposited ~650.000 XVG to your wallet on yobit with this transaction: https://www.blockexperts.com/xvg/tx/a392692ef6b02d295f9b04c150b4d04c5142ff2daba585339fbd22e2b8fb3e6cthe wallet was online at the time of the deposit After ~24h, they took the wallet offline, but didn't credit your account You sent them a ticket and a PM, and instead of answering you they banned you. Just a couple more things: - is this correct, or did i made a mistake
- are you 100% sure that you're banned from yobit? So you cannot login and make a screenhost of your XVG deposit wallet in order to prove that you sent the XVG to the correct wallet
- Can you give us the timing (when did this happen, when did you contact support, when did you send a PM)

thanks dude, i will run it in cygwin  If you cannot get it fixed, let us know and i'll rewrite it in perl (not much work, but i won't do it if it's not needed) |

I have lost money there and they did not respond. and many others are also experiencing the same thing . not just me .
Unless you clarify how you lost money, you've still not explained anything. A gambler could get angry at a casino for losing all his money, doesn't mean it was the casino's fault. The only time I have used Yobit is for the signature campaign, but it seems very professional and well coded. I did not lose because of gambling but I have to make a deposit tx a392692ef6b02d295f9b04c150b4d04c5142ff2daba585339fbd22e2b8fb3e6c and they did not answer me for a week , and now they banned my account . So, if i understand correctly, you made a deposit with tx id a392692ef6b02d295f9b04c150b4d04c5142ff2daba585339fbd22e2b8fb3e6c and it did not show up in your account? However, blockchain.info doesn't know about this transaction: https://blockchain.info/search?search=a392692ef6b02d295f9b04c150b4d04c5142ff2daba585339fbd22e2b8fb3e6cOr was it an altcoin? I need a bit more info to get to the bottom of this |

I'm using perl in window, and encounter an error as below. Do i have to define the variables like i='(A..Z)' ?? C:\Strawberry\perl\test>perl test.pl Missing $ on loop variable at test.pl line 1. for i in `perl -e '$,=" ";
print +(A..Z),(a..z),(0..9)'`; "for i in something; do something; done" is not perl. It's bash, and I don't think you get that in stock windows boxes even today. Install cygwin and try there. ^^ this is correct... I'm running on a linux box (and i wrongly assumed so were you), so it's basically a combination between bash and perl (which is installed by default on 90+% of the linux distros, but not on windows... you need something like mobaXterm or cygwin with some addons to do this task)... Did you get this solved, or do i have to rewrite it in pure perl? |

Pull all your coins off of @YobitExchange while you can. Exchange wide meltdown aka cryptsy round 2 inbound.
Can you tell us why you're posting this? Are you having any problems, can you post some transactions, screenshots,... or at least some more info??? |

- custom written faucets - faucet box (like you said already) - https://github.com/search?utf8=%E2%9C%93&q=bitcoin+faucetBe carefull with github: a lot of those faucet scripts seems really old, no recent updates, no discussion, only 1 contributor: it might take a while to find a good one, but you can always give it a try |

I want to buy something for $350 using bitcoin. I saw a video saying to use paypal for my first purchase had to be $50, then after a week or so, it goes up. I can use paypal or a debit card, but don't want to wait to send the total. Please point me in the right direction! Thank
I'm a bit confused about your problem. You want to buy something, but can only pay in bitcoin. Somebody? told you to use paypal to buy bitcoin, and this confuses you. Is this correct, or am i missing something? |

Excellent find, only their table's sort function is kinda wonky: if you sort by price (annually), it assumes that 10 is smaller than 2 (common sorting problem when assuming the price is a string instead of a decimal)

the collateral that i give is my facebook profile twiter and a website. trust me i'm a good partner
how send me , give me his adresse and i will give back his loans at time
Those are pretty much useless collateral. Depends on the domain he's willing to give as collateral... should be a pretty good one to cover $1200 + 20% = $1440 tough. @OP: why don't you list the domain and other accounts you're offering as colateral? |

Hi all bitcointalker's,
I need a small loans of 3 bitcoins! i will give you a returne of 4.5 btc next 2 months, please i need it verry hard.
here my address wallet: 19LSypAy55PL8fEkw385Fz24LPDMwUxPX9
Thank you! giving this help
How can you put the words small and 3 BTC in one scentence? I suggest trying out btcjam.com, because here chances of getting such a loan without collateral with a newbie status will be very slim |

Can you tell me your level of expertise, your budget,...
Without a lot of knowledge and a big budget, it might be best to start an informative site about bitcoin (a blog, a forum, a review site,...). Make sure you offer new (unique) and interesting articles, links, reviews,...
Ask other website owners for link exchanges, like SFR10 said: do some social network engineering... Really get a lot of visitors.
When your site is big, put adds on some places (there are a couple sites like a-ads or coinurl that make this really easy).
If your site grows even bigger, you might sell slots on your blog, or premium places for external links,... in order to maximise your revenue...
If you have a very specific skillset, and a bigger budget, other options might become more interesting for you, but you'll have to tell us what you can do, and how much money you're willing to spend.
