I have a wallet with a non-trivial amount of BTC.
I have some idea of what's the password, but can't bruteforce it myself, perhaps someone who runs a recovery service can do it for a fee?
Is there a way to give one of the keys with no funds?
Let me know, there's over $5000 involved for whoever can help.

So, I want to get the private keys of a backup. Is there a way to do it without syncing Armory?
Thanks.

Hello, I need regexs for addresses, keys and if they exist for that crypto currency, master private and public keys.

Examples:

Bitcoin address \b[13][a-km-zA-HJ-NP-Z0-9]{33}\b 1MKVGqyJA9YkVRuDsGCvnYVJ6ivNtfe289

Bitcoin XPUB key (master public key for HD wallets) \b(xpub)[a-km-zA-HJ-NP-Z1-9]{107,107}\b xpub661MyMwAqRbcF3n3Sg6dL7C29vTi8prxevmhoDLLR6VJTetHp3rKGDQFzNSvVBZ2oxkepHnu1TE Wx1hiLjEvJ3rS3bRQQapr1BSyBzzz5JE Ethereum address \b0x?[0-9a-f]{40}\b 0x0dE0BCb0703ff8F1aEb8C892eDbE692683bD8030

The list should include at least 2 examples for each category so I can check it. It should be one example with address/key in the middle of a phrase and the other on a new line, after some unrelated text on the previous line.

If you can do it, please tell me your price and time it would take.

To summarize, it's a web bot to register domains, buy hosting and configure everything.

- From a list of identities (name, address, e-mail address) provided in CSV format, it should create an account at a domain one of the 3 domain registrars listed below, alternating them in order
- After the account is created (which may require solving a captcha), it should confirm the e-mail address, if necessary
- It should do the same process, now with one of the 3 hosting services listed below
- After that, it should take a domain name from a CSV file and buy it. Payment method will be bitcoin, which will be done by an app written by me. It needs to receive address and amount. Can be sent to it via JSON, by writing to a file. After it's bought it should be moved to another CSV file
- Next step is to purchase a hosting plan
- With that completed, it should wait until the hosting is enabled and assign the DNS records on the hosting to either the IP address of the hosting or delegating the nameservers, depending on the case
- When the DNS resolution is OK, after a few hours, it should upload the site (calling a script I have, very simple)
- After that, it should access the site and look for a string in the text, which will vary per site, to check it was uploaded correctly
- Both these checks should be done on all sites that are functioning on a regular basis, to see if any problems arise
- It should also notify the user when the domain is less than 30 days from expiration and handle the process
- The bot should also have saved when the hosting provider will expire and renew 5 days before
- The UI should notify the user what it's doing and be able to start and stop the process, saving the progress
- It should also be able to handle properly any problems that might arise, such as connection issues or notify the user if there's a problem using the site, if they changed the layout, for example
- The software should allow to change the hosting of a registered domains, by buying a new hosting plan and reassigning the information for that domain

I believe Ubot is ideal for the interaction with the registrar and hosting services, I have a license I could lend you if you don't have it. For the interface and health checks, I'd prefer C#.

Hello!

I need someone to log into my account at ubotstudio.com and pay for support for one year.
I could do it myself, but I'm tired of paypal, they blocked an account with a few thousands last year and was a hassle.
So the idea is you login, pay with yours and that's it. The price is $97.

I could pay you $20 more or so for time it takes.

Let me know!

I need a simple Bittrex trading bot in C#. There are a few here: https://github.com/search?l=C%23&q=Bittrex&type=Repositories&utf8=%E2%9C%93

I need the best one from Github (or a better one from somewhere else if you can find it) updated to use 1.1 of Bittrex's API (they are deprecating 1.0, see here https://www.bittrex.com/Home/Api).

The requirements are simple:

- Wait for an order to either buy any of the cryptos at Bittrex
- Check the account balance to see it has enough
- Check the price 1 minute before receiving the order and at present time. If price is higher than a given percentage, cancel the purchase, otherwise continue
- Send the order, monitor it and reply the caller when it's processed in the order book
- Monitor the last trade price continuously, as fast as Bittrex allows. When a given threshold is reached (a percentage over purchase price), sell
- If price falls over a certain price, say 1.5 times original price, sell at the original price

Basically need to read the addresses and keys of a few wallets for which I have the password.
How can I decode them?
Any pointers to tools or where to look in the code?

Thanks.

When I click "Sign", it times out of some remote connection in about 10 seconds and says "server did not answer".
I'm trying to just sign a TX hex I copied from a watch only.
I can do it perfectly on 2.7.11.

Why would Electrum need to contact a server in order to sign a transaction?

So I downloaded my wallet file using "python -c "import urllib2,json;f=urllib2.urlopen('https://blockchain.info/wallet/WALLET-D-STRING?format=json');print json.loads(f.read())['payload']" > wallet.json.aes"

So far so good.
My problem is that I can't run btcrecover with it. Tried extracting the payload and with the original file and nothing.

Any help? $20 for whoever gives me the correct answer first, just give your address, if I can make it run, I'll send it.

When running:

Code:

python btcrecover.py --wallet wallet.aes.json --tokenlist tokens

I'm getting

Code:

Traceback (most recent call last): File "btcrecover.py", line 35, in <module> btcrpass.parse_arguments(sys.argv[1:]) File "/home/user/btcrecover-master/btcrecover/btcrpass.py", line 3420, in parse_arguments parse_tokenlist(tokenlist_file, tokenlist_first_line_num) File "/home/user/btcrecover-master/btcrecover/btcrpass.py", line 3691, in parse_tokenlist if line.startswith("#"): UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 21: ordinal not in range(128)

Thanks!

Hi, the dumpwallet command throws the private keys and a xprv.
Can I use it to derive all future addresses from the wallet? I'm a bit out of sync, I didn't know the reference client implemented HD keys.

If so, could anyone tell me the derivation path used?

Thanks!

Hello!

I'm trying to dump my wallet using pywallet.
Getting some strange errors, wallet was created with bitcoin 0.13.
Here's a partial log with sensitive information removed.
Can anyone recommend a version that is working with the latest Bitcoin binaries?

There's an error about bitcoin running at the time but it wasn't.

Code:

Wallet data not recognized: {'__type__': 'keymeta', '__value__': 'REMOVED', '__key__': '\x07keymeta!REMOVED'}


error: unpack_from requires a buffer of at least 4 bytes
ERROR parsing wallet.dat, type tx

So, I have 5 BTC stored "safely" in a paper, that I put in a safe... but the ink has faded partially, so now I'm going insane trying to figure out if something is a G or a 6, an a or 9 (seriously).

Is there a script to brute force the possible combination of characters that look similar in a private key?

It's this, http://www.babelfor.net/Shop

If you can do it, tell me the price. Only users with some good reputation here.
Thanks.

Title, basically.
Is there a way to derive from the two phrases composed of words of 4 letters each?

I'm working with the RPC now.
I have spendzeroconfchange activated.
Tried to send a transaction using unconfirmed inputs but I wasn't able to, I was told I didn't have enough balance.

Is it not possible to do it?

Only trusted users. Send me a PM and I'll send you the details.

Thanks.

Edit: I've solved it, people, thank you.

[EDIT:]

Hey people, hope this is relevant to this forum.

I'm writing a bot that for now is getting information from a market, in this case it's Poloniex. I pull the chart data. Polo supports every 5, 15 and 30 minutes and higher.

I'm writing a method to calculate the progression of the value for bitcoins, in dollars, over time.

What I'm doing is this:

We start with a capital of, say, $10,000 in bitcoins.

Say in a given period bitcoin went from 560 to 580. The change in this case would be 580/560 = 1.035714286, an increase of about 3.57%. After this period, we have, in dollars, 10000*1.035714286 = $10,357.14

Next period, values were 580 and 570, so the multiplier to calculate the loss is 0.982758621, giving us $10,178.57.

So far so good. I'm calculating this for a few weeks with the information I'm getting from Polo.

My problem is that if I process this with a higher frequency (5 minutes vs 15 minutes), the final value is much higher (in case of a bull market, lower if it was bearish). The lower the frequency, the lower the final value.

I'm probably having a pretty big conceptual error about markets high & lows or something I can't see.

Could you give me a hand? Why is that calculating this with a higher frequency gives me such a wildly different result?

Thank you!

EDIT:

Checked the reply from the Polo API and clearly there's something I don't understand.
The close value of period 1 (say, 08/15) is not the same as the open value of period 2 (08/16).

What am I missing here?
