I have some coin, what now?

Hi all. New here but I had a question, I have a wallet.dat file in my hard drive with some bitcoin in it, but I don’t know where to go from here. What can I do with this wallet and what software will I need to do these things. I am not super interested in caching out, I would like to keep it or sell it later or make it usable to buy things. Thanks for the assistance!
Edit: Got it! Used armory as core wouldnt work for some reason

Armory Wallet Has Failed Me! Can I recover BTC?

So I opted to migrate from coinbase to a local wallet.
Naturally, I download Armory and shoot it a send for 1BTC. 225 confirmations on the SEND, but wallet never receives it.
Turns out, running Armory wallet has been corrupting my database. Every time I run it a background process it spawns causes Bitcoin-QT to fail.
I've tried uninstalling and re-installing bitcoin, armory wallet three times. I've deleted my bitcoin directory in %appdata%, ensured downloads are never interrupted.
Is there any way at all for me to recover the BitCoin I sent to armory wallet provided I can never get armory wallet to work correctly?
Any help appreciated. Here is the errors:
2015-08-21 14:48:15 init message: Activating best chain... 2015-08-21 14:49:23 Corruption: block checksum mismatch 2015-08-21 14:49:23 *** System error while flushing: Database corrupted

HELP! Bitcoin qt client crashed on my computer with a database error! Lost all my bitcoins?!

hey guys,
The bitcoin qt client was catching up with the blockchain (5 days worth), when after maybe 15 minutes, it comes up with an error, "database corrupted" or something along the lines of that. I looked it up and users said to delete everthing in my %appdata/roaming/bitcoin% directy except the wallet.dat file.
So I did that, and downloaded the latest bitcoin qt client, but as it's got 252 weeks to catch up on, it shows 0 btc, is this normal? Will it show my bitcoins whilst it's done updating?
It should show it at the end, right? Once it's seen the transactions on the blockchain? Sorry, I'm just ultra panicky atm from not seeing my bitcoins :S
EDIT: GOT MY BITCOINS. For anyone that has this problem in the future, it's 99.99% likely it's a RAM problem. Took my dodgy ram stick out and used a rescan tag & it was all good to go! You can also import the boostrap.dat file.

(1) Is it true that encrypting an *existing* bitcoin-qt wallet.dat file will "invalidate" any existing backups? (2) Can I use unicode characters - eg ♥ - in the bitcoin-qt wallet passphrase?

I have an existing bitcoin-qt wallet.dat file which I want to encrypt - using the command in the bitcoin-qt Settings menu, involving creating a passphrase.
I have 2 (possibly somewhat related) questions:
TL;DR
(1) If you encrypt an existing wallet.dat file, will the backups of the old wallet.dat file still work?
(2) Can you include unicode characters - eg ♥ - in the passphrase used to encrypt a bitcoin-qt wallet.dat file?
Worst-case scenario: The answers to (1) and (2) are both "no" - and I attempt to encrypt an existing wallet using unicode, and my backups no longer work (due to a new pool of addresses somehow being created?) and the passphrase isn't what I think it is (due to the unicode characters somehow being misinterpreted?) - and then I could lose all my coins??
Details
(1) The following (old, short) thread claims that after you encrypt an existing wallet, any previous backups of that wallet will no longer work:
https://pay.reddit.com/Bitcoin/comments/1ccfdk/encrypting_walletdat_in_bitcoinqt/
Obviously, the the first response in that thread was slightly wrong, for saying that the "server" creates a new pool of 100 addresses to draw on. So using word "server" here was certainly incorrect - but maybe the gist of what they were saying might still be correct? (if you simply change "server" to "client").
I can actually understand that there might be reasons why encrypting a wallet.dat file could cause a new pool of 100 addresses to be generated.
But it does not make sense to me that this would make any older (unencrypted) backups instantly useless.
It seems to me that these older, unencrypted backups would still have their private keys intact, and could thus be used in certain (perhaps limited?) ways - such as:

(2) It seems that including a few unicode characters in the bitcoin-qt wallet passphrase would make it a lot stronger (since unicode is a much larger set of characters than ascii), so I would like to include a few.
But it would be more reassuring if it could be explicitly stated that this is indeed supported.

Possible catastrophic interaction between (1) and (2)?
If the answers to (1) and (2) were both "no" (ie, if you encrypt an existing bitcoin-qt wallet.dat file then any existing backups will not work, and unicode characters do not work in bitcoin-qt passphrases), then I'm worried there could be some kind of catastrophic interaction between (1) and (2) where I lose all my coins, as follows:
(1) I encrypt my existing wallet - making my old, unencrypted wallet.dat file now invalidated (due to something involving a new pool of addresses being generated?)
and
(2) I use a passphrase which includes unicode characters which bitcoin-qt appears to accept at the time of creation, but which doesn't work at the time of trying to decrypt the wallet.dat file (due to something going wring with how the supposed unicode characters are actually interpreted while being entered or copied-and-pasted?).
In this possible worst-case scenario, my old backups of wallet.dat no longer work, and my newly encrypted wallet.dat has some password which I'm not able to correctly enter anymore.
Sorry to be so paranoid about this!
Other remarks:
(a) I did do a (limited) test of unicode capability for bitcoin-qt wallet.dat passphrases: simply by creating a new (empty) wallet.dat file, and creating a passphrase for it involving unicode characters, and then attempting to change the passphrase (which requires entering the old passphrase that contained unicode characters).
This did seem to work ok: it let me re-enter the old passphrase (which included unicode characters) to create a new passphrase.
However, since this is an empty wallet (and since bitcoin-qt would ask for the passphrase only when attempting to actually spend from an encrypted wallet), I did not see a way to fully test whether the passphrase actually worked to decrypt a unicode-passphrase-encrypted wallet for the purpose of spending from it.
(I'm still downloading the rest of the blockchain and it's going to take at least another week on my slow connection, so don't see how I could send a small amount to the new wallet to test it either. My existing wallet.dat file was originally created on an internet-connected machine a long time ago, but it's been offline ever since, so in some sense it's kinda-sorta been in somewhat "cold" storage all this time, and I would prefer to avoid putting it online on a "hot" internet-connected machine until absolutely necessary.)
(b) Long-term, I am actually also in the process of setting up a proper cold storage system based on Armory, which I have installed on 2 Ubuntu machines (one offline and one online).
But I have a slow internet connection, and the backups of this old wallet.dat file have been sitting around unencrypted for ages (I've been relying simply on then being physically inaccessible).
Now some "things" are coming up over the next few days where I some better security right away, and it's probably going to take over a week for Armory/bitcoind to update my local copy of the blockchain.
So in the meantime, I also need some basic additional security right now - so encrypting the existing bitcoin-qt wallet.dat file using a strong passphrase (and making some new backups) seems like it could be a reasonable initial approach.
Thanks for any help!

Corrupted wallet.dat with 18 btc - Possible to restore bitcoins?

I have a wallet from yore, had 18 btc that got corrupted and I kind of just lost interest in bitcoins. Well now that 18 is woth $2K or so and I fired up a new bitcoin-qt wallet with that wallet.dat file to see if it would read it. Well it almost did.
The GUI read 18 unverified bitcoins at first, and as the blockchain neared completion, it verified every bitcoin. I was so excited. But then it crashed with a runaway exception "can't open database file wallet.dat -30974"
I get that error when I try to send a bitcoin too. Any chance of restoring this near-working wallet?
EDIT: Bitcoins have been recovered!!!!!!! The final solution was provided by musicbunny, to which I am extremely greatful for his out-of-the box solution. I think pywallet suggested by eof would have done the trick too. The keys probably could have been extracted, but I was running into trouble with my version of Python. Maybe it needed Python 2?

Question about Armory

Hi all. Fairley new to cryptocurrency, however that didn't stop me from buying some months ago. Anyway, I stored some smaller pieces of BTC onto my armory wallet and let them sit there for a while. Now when I'm trying to open armory, I get a runtime error once it gets to about 95% of verifying the transactions.
Any advice on how I can fix this?

Disk Digger Pro Apk || DiskDigger Importance || Recover Lost Files

In the Present scenario, Technology is growing too fast and we all are experiencing that our smartphone, PC, and Laptops carrying various files with the help of SD cards and internal memory. We will think that our files are in very secure places but if any file deleted unexpectedly then what you will do?. Don't worry, I already told you that tech is growing as fast as it can. Here I'm going to discuss the best data recovery services aka (DiskDigger) which are a perfect example of it. Let's go down to get more details of DiskDigger( Deep file recovery from any drive).
DiskDigger is a tool which can recover deleted files like photos, documents, music, video and much more.
DiskDigger Features:
DiskDigger can recover lost files from most types of media that your computer can read: hard disks, USB flash drives, memory cards, CDs, DVDs, and floppy disks. (Note: Make sure that you have to connect your device with a USB port to recover lost data from Android and IOS devices ). And one more important thing is you have to download the diskdigger app on your android phone to recover lost files. Suppose if your Android device uses a microSD card for saving the data, please remove the card and connect it directly to your PC using a card reader, so that you can scan it directly using DiskDigger for Windows.)
DiskDigger has two processes which you have to choose every time while scanning a disk. These methods are named as “dig deep” and “dig deeper“.

Dave Bitcoin of walletrecoveryservices.com just cracked a wallet for me (whose passphrase I lost in May).

Background:
In May I got the "brilliant" idea of beefing up the security of my BitcoinQT wallet by replacing its password with a longer passphrase. Somehow I managed to mistype the passphase twice. I tried every thing I could think of (adding spaces, inverting capitalization, etc. etc.) but without success, even automating the guesses with a simple script from someone on bitcointalk.
Eventually I wrote the coins off and my next wallet passphrase was typed with extreme caution. (Plus I switched to using Armory where the paper backup feature is a nice safety valve.) I gave the wallet.dat file to a few people who contacted me via the bitcointalk forums, and thought that was the end of it.
So last night, I'm obsessively watching the BTC-CNY exchange rate like everyone else, when I get an email from one "Dave Bitcoin" who announced that he had cracked the passphrase (after more than 5 months!). In short order he sent me 2.0 of the original 2.5 BTC in the wallet (keeping a finder's fee we had agreed to when I originally sent him the wallet file, not that I was in a particularly good bargaining position).
It was a very pleasant surprise that he (a) was able to crack the wallet, and (b) was honest enough to return the coins. He mentioned in the email that part of his motivation for (b) is that he has started a business doing wallet recovery. I figure the least I can do is vouch for his competence and integrity. So all you morons out there who lost a wallet like me, consider using Dave's services at http://walletrecoveryservices.com/.

Secure paper wallet tutorial

This is my handout for paranoid people who want a way to store bitcoin safely. It requires a little work, but this is the method I use because it should be resistant to risks associated with:
  1. Bad random number generators
  2. Malicious or flawed software
  3. Hacked computers
If you want a method that is less secure but easier, skip to the bottom of this post.
The Secure Method
  1. Download bitaddress.org. (Try going to the website and pressing "ctrl+s")
  2. Put the bitaddress.org file on a computer with an operating system that has not interacted with the internet much or at all. The computer should not be hooked up to the internet when you do this. You could put the bitaddress file on a USB stick, and then turn off your computer, unplug the internet, and boot it up using a boot-from-CD copy of linux (Ubuntu or Mint for example). This prevents any mal-ware you may have accumulated from running and capturing your keystrokes. I use an old android smart phone that I have done a factory reset on. It has no sim-card and does not have the password to my home wifi. Also the phone wifi is turned off. If you are using a fresh operating system, and do not have a connection to the internet, then your private key will probably not escape the computer.
  3. Roll a die 62 times and write down the sequence of numbers. This gives you 2160 possible outcomes, which is the maximum that Bitcoin supports.
  4. Run bitaddress.org from your offline computer. Input the sequence of numbers from the die rolls into the "Brain Wallet" tab. By providing your own source of randomness, you do not have to worry that the random number generator used by your computer is too weak. I'm looking at you, NSA ಠ_ಠ
  5. Brain Wallet tab creates a private key and address.
  6. Write down the address and private key by hand or print them on a dumb printer. (Dumb printer means not the one at your office with the hard drive. Maybe not the 4 in 1 printer that scans and faxes and makes waffles.) If you hand copy them you may want to hand copy more than one format. (WIF and HEX). If you are crazy and are storing your life savings in Bitcoin, and you hand copy the private key, do a double-check by typing the private key back into the tool on the "Wallet Details" tab and confirm that it recreates the same public address.
  7. Load your paper wallet by sending your bitcoin to the public address. You can do this as many times as you like.
  8. You can view the current balance of your paper wallet by typing the public address into the search box at blockchain.info
  9. If you are using an old cell phone or tablet do a factory reset when you are finished so that the memory of the private keys is destroyed. If you are using a computer with a boot-from-CD copy of linux, I think you can just power down the computer and the private keys will be gone. (Maybe someone can confirm for me that the private keys would not be able to be cached by bitaddress?)
  10. To spend your paper wallet, you will need to either create an offline transaction, or import the private key into a hot wallet. Creating an offline transaction is dangerous if you don't know what you are doing. Importing to a client side wallet like Bitcoin-Qt, Electrum, MultiBit or Armory is a good idea. You can also import to an online wallet such as Blockchain.info or Coinbase.
Trusting bitaddress.org
The only thing you need bitaddress.org to do is to honestly convert the brainwallet passphrase into the corresponding private key and address. You can verify that it is doing this honestly by running several test passphrases through the copy of bitaddress that you plan on using, and several other brainwallet generators. For example, you could use the online version of bitaddress, and brainwallet and safepaperwallet and bitcoinpaperwallet. If you are fancy with the linux command line, you can also try "echo -n my_die_rolls | sha256sum". The linux operating system should reply with the same private key that bitaddress makes. This protects you from a malicious paper wallet generator.
Trusting your copy of bitaddress.org
Bitaddress publishes the sha1 hash of the bitaddress.org website at this location:
https://www.bitaddress.org/pgpsignedmsg.txt
The message is signed by the creator, pointbiz. I found his PGP fingerprint here:
https://github.com/pointbiz/bitaddress.org/issues/18
"527B 5C82 B1F6 B2DB 72A0 ECBF 8749 7B91 6397 4F5A"
With this fingerprint, you can authenticate the signed message, which gives you the hash of the current bitaddress.org file. Then you can hash your copy of the file and authenticate the file.
I do not have a way to authenticate the fingerprint itself, sorry. According to the website I linked to, git has cryptographic traceability that would enable a person to do some research and authenticate the fingerprint. If you want to go that far, knock yourself out. I think that the techniques described in this document do not really rely on bitaddress being un-corrupt. Anyway, how do we know pointbiz is a good guy? ;-)
There are a lot of skilled eyes watching bitaddress.org and the signed sha1 hash. To gain the most benefit from all of those eyes, it's probably worthwhile to check your copy by hashing it and comparing to the published hash.
"But we aren't supposed to use brainwallets"
You are not supposed to use brainwallets that have predictable passphrases. People think they are pretty clever about how they pick their passphrases, but a lot of bitcoins have been stolen because people tend to come up with similar ideas. If you let dice generate the passphrase, then it is totally random, and you just need to make sure to roll enough times.
How to avoid spending your life rolling dice
When I first started doing this, I rolled a die 62 times for each private key. This is not necessary. You can simply roll the die 62 times and keep the sequence of 62 numbers as a "seed". The first paper address you create would use "my die rolls-1" as the passphrase, the second would be "my die rolls-2" and so on. This is safe because SHA256 prevents any computable relationship between the resulting private key family.
Of course this has a certain bad security scenario -- if anyone obtains the seed they can reconstruct all of your paper wallets. So this is not for everyone! On the other hand, it also means that if you happen to lose one of your paper wallets, you could reconstruct it so long as you still had the seed.
One way to reduce this risk is to add an easy to remember password like this: "my die rolls-password-1".
If you prefer, you can use a technique called diceware to convert your die rolls to words that still contain the same quantity of entropy, but which could be easier to work with. I don't use diceware because it's another piece of software that I have to trust, and I'm just copy/pasting my high entropy seed, so I don't care about how ugly it is.
Why not input the dice as a Base 6 private key on the Wallet Details tab?
Two reasons. First of all, this option requires that you roll the die 99 times, but you do not get meaningful additional protection by rolling more than 62 times. Why roll more times if you don't have to? Second, I use the "high entropy seed" method to generate multiple private keys from the same die rolls. Using the Base 6 option would require rolling 99 times for every private key.
I'm a big nerd with exotic dice. How many times to roll?
Put this formula in Excel to get the number of times to roll: "=160*LOG(2,f)" where f = number of faces on the die. For example, you would roll a d16 40 times. By the way, somewhat unbelievably casino dice are more fair than ordinary dice
The "Change address" problem:
You should understand change addresses because some people have accidentally lost money by not understanding it.
Imagine your paper wallet is a 10 dollar bill. You use it to buy a candy bar. To do this you give the cashier the entire 10 dollar bill. They keep 1 dollar and give you 9 dollars back as change.
With Bitcoin, you have to explicitly say that you want 9 dollars back, and you have to provide an address where it should go to. If you just hand over the 10 dollar bill, and don't say you want 9 dollars back, then the miner who processes the transaction gives 1 dollar to the store and keeps the remainder themselves.
Wallet software like Bitcoin-Qt handles this automatically for you. They automatically make "change addresses" and they automatically construct transactions that make the change go to the change address.
There are three ways I know of that the change problem can bite you:
  1. You generate a raw transaction by hand, and screw up. If you are generating a transaction "by hand" with a raw transaction editor, you need to be extra careful that your outputs add up to the same number as your inputs. Otherwise, the very lucky miner who puts your transaction in a block will keep the difference.
  2. You import a paper wallet into a wallet software and spend part of it, and then think that the change is in the paper wallet. The change is not in the paper wallet. It is in a change address that the wallet software generated. That means that if you lose your wallet.dat file you will lose all the change. The paper wallet is empty.
  3. You import a paper wallet into a wallet software and spend part of it, and then think that the change is in the change address that the wallet software generated. If the transaction did not need to consume all of the "outputs" used to fund the paper wallet, then there could be some unspent outputs still located at the address of the paper wallet. If you destroyed the paper wallet, and destroyed the copy of the private key imported to the wallet software, then you could not access this money. (E.g. if you restored the software wallet from its seed, thinking all of the money was moved to the wallet-generated change addresses.)
For more on this, see here
The hot paper wallet problem
Your bitcoin in your paper wallet are secure, so long as the piece of paper is secure, until you go to spend it. When you spend it, you put the private key onto a computer that is connected to the internet. At this point you must regard your paper wallet address as hot because the computer you used may have been compromised. It now provides much less protection against theft of your coins. If you need the level of protection that a cold paper wallet provides, you need to create a new one and send your coins to it.
Destroying your paper wallet address
Do not destroy the only copy of a private key without verifying that there is no money at that address. Your client may have sent change to your paper wallet address without you realizing it. Your client may have not consumed all of the unspent outputs available at the paper wallet address. You can go to blockchain.info and type the public address into the search window to see the current balance. I don't bother destroying my used/empty paper wallet addresses. I just file them away.
Encrypting your private key
BIP 0038 describes a standardized way to encrypt your paper wallet private key. A normal paper wallet is vulnerable because if anyone sees the private key they can take the coins. The BIP38 protocol is even resistant to brute force attacks because it uses a memory intensive encryption algorithm called scrypt. If you want to encrypt your wallets using BIP38, I recommend that you use bitcoinpaperwallet because they will let you type in your own private key and will encrypt it for you. As with bitaddress, for high security you should only use a local copy of this website on a computer that will never get connected to the internet.
Splitting your private key
Another option for protecting the private key is to convert it into multiple fragments that must be brought together. This method allows you to store pieces of your key with separate people in separate locations. It can be set up so that you can reconstitute the private key when you have any 2 out of the 3 fragments. This technique is called Shamir's Secret Sharing. I have not tried this technique, but you may find it valuable. You could try using this website http://passguardian.com/ which will help you split up a key. As before, you should do this on an offline computer. Keep in mind if you use this service that you are trusting it to work properly. It would be good to find other independently created tools that could be used to validate the operation of passguardian. Personally, I would be nervous destroying the only copy of a private key and relying entirely on the fragments generated by the website.
Looks like Bitaddress has an implementation of Shamir's Secret Sharing now under the "Split Wallet" tab. However it would appear that you cannot provide your own key for this, so you would have to trust bitaddress.
Durable Media
Pay attention to the media you use to record your paper wallet. Some kinds of ink fade, some kinds of paper disintegrate. Moisture and heat are your enemies.
In addition to keeping copies of my paper wallet addresses I did the following:
  1. Order a set of numeric metal stamps. ($10)
  2. Buy a square galvanized steel outlet cover from the hardware store ($1)
  3. Buy a sledgehammer from the hardware store
  4. Write the die rolls on the steel plate using a sharpie
  5. Use the hammer to stamp the metal. Do all the 1's, then all the 2's etc. Please use eye protection, as metal stamp may emit sparks or fly unexpectedly across the garage. :-)
  6. Use nail polish remover to erase the sharpie
Electrum
If you trust electrum you might try running it on an offline computer, and having it generate a series of private keys from a seed. I don't have experience with this software, but it sounds like there are some slick possibilities there that could save you time if you are working with a lot of addresses.
Message to the downvoters
I would appreciate it if you would comment, so that I can learn from your opinion. Thanks!
The Easy Method
This method is probably suitable for small quantities of bitcoin. I would not trust it for life-altering sums of money.
  1. Download the bitaddress.org website to your hard drive.
  2. Close your browser
  3. Disconnect from the internet
  4. Open the bitaddress.org website from your hard drive.
  5. Print a paper wallet on your printer
  6. Close your browser

How do I access the funds in a file called "money.bit"

I've been bitcoining for a few years, and have an old file I've been meaning to try and access for a couple of years.
It begins:
{"privateKey":"{\"iv\":\"lettersnumberssymbols",\"v\":1,\"iter\":10000,\"ks\":128,\"ts\":64,\"mode\":\"ccm\",\"adata\":\"\",\"cipher\":\"aes\",\"salt\":\"lettersnumberssymbols",\"ct\":\"lettersnumberssymbols/alphanumeric/E\"}","encryption":"sjcl"}
I've replaced the bits I believe are sensitive.
I can't remember which program this file is designed to work with. I've tried loading one of the alphanumeric as a private key, but one of the attributes is salt, and I don't think it's quite as simple as just reading it as a text file and cutting and pasting one of the strings into the import private key feature on blockchain.info.
It's a .bit file rather than a .dat or something else... unless I renamed it at some point to end .bit, to remind myself what it was, which is quite possible - it may have begun life with no file extension (I'm a Linux user).
I've already tried the contents with electrum, and I've used quite a few wallets in the past so I've been poking around bread, electrum, mycelium, and can't quite see how this wallet would fit with any of those. I've used (well, installed) armory, multibit, as well as used things like online wallet generators.
So I'm a bit stuck as to what to do, hoping someone recognizes this format!

.01 from 2011

I just found an old wallet.dat file from 2011. Armory and Exodus and don't seem to be able to recognize/load in the file. Electrum doesn't seem to work on my computer despite a few hours of troubleshooting.
I have bitcoin core, and tried to send a transaction yesterday. It posted, but was never confirmed. I was able to delete the mempool.dat file; and open bitcoin core using -broadcast = 0, and it abandoned the transaction.
I resent the transaction with a .002 transaction fee, but it is giving this message:Status: 0/unconfirmed, in memory pool
The transaction ID doesn't show on a site like blockcypher.
aaand of course, with Bitcoin Core, it says it is synching with the network because I am 5 years and 8 months behind, and it is going SOOOO SLOW. I don't know if that is causing the problem.
My goal is just to get this darn .01 bitcoin to coinbase and sell it, so I can buy a family member an extra christmas present. I've spent maybe 7 hours troubleshooting this. What would you do in this situation?

Completely lost with Armory

Hey everyone, total noob here with BTC. I've downloaded the blockchain from Bitcoin Core and now I'm trying to get Armory (where I've set up a wallet and sent funds to already) to sync up. Armory still shows up as Offline and it's been "preparing databases" for a good two or three hours now. I'm not sure if I'm just going to be playing the waiting game until it does what it needs to do, or if I need to move a file somewhere, or if my settings are wrong.
I do have a printed backup of my wallet just in case. If I've completely f'd this up, is it possible to send that wallet's .dat over to Core or another program and have it sync up there? Thanks.

Help me recover my bitcoins from my wallet backups.

Hey guys.
The history: In 2013 or 2014 I bought 1 BTC and I stored it in one wallet (don't remember which). I have a wallet.dat in my PC and an Armory wallet backup on pdf (paper).
The Armory Backup was encrypted and now I can't see public addresses, but AFAIK this shouldn't be an issue because the backup was done later than the last transfer. How can I know if there are bitcoins in the paper wallet? I've had lots of problems with Armory and can't manage to sync the blockchain.
On the otherhand I have a HDD from that era with Bitcoin QT installed and a wallet.dat there. The thing is that I can't access that wallet and I don't know if the funds are there. How can I tell if there are BTCs there?
I checked the last public key used and still it has the money in it (checked n blockchain.info)
The last option is that I transferred that 1 BTC to other wallet that I lost and never backed-up, but I think this is very unlikely.
Is there anything I can do to find my missing bitcoins?

Bitcoin client comparison? Ease of use, functionality, security etc..

Hey everyone,
I've recently started using bitcoins, and been trying to figure out the best way to store them.. There are a bunch of desktop clients available, each with it's ups and downs, supporting different features, and using different amount of resources..
I wanted to find a nice overview of them all, but so far I'm not finding anything that I wanted to know.. So I think we should have some kind of wiki page, that describes them in more details. Explains how to start using each of them, and how to ensure it's safe.
For example, to try and secure my wallet files, I'm storing them in a TrueCrypt volume, that's archived to the cloud. This way they are backed up to multiple locations, incase my machine dies, and are also encrypted, in case one of the machines is compromised! I'm not sure if that's overkill or not :)
I thought I'd start with a short write-up of my opinions on some of the clients and my impressions of them. It's by no means a comprehensive review (that would take a lot more space than a single reddit post). All of this is just a subjective view on each of the clients.. I hope more people will add to it, maybe even compoling a nice and informative comparison of all the popular clients!
  1. Bitcoin-QT: The official client. Somewhat basic in functionality, advanced functions (like backing up the private key) available through the "debug" window., but works well for a lot of people.. You can backup the wallet.dat file in the TrueCrypt volume to secure the coins, but the client will store the main working copy of the wallet file in %APPDATA% in Windows - leaving it potentially compromised, unless you encrypt the wallet file (part of the client's functionality). There's no obvious way to change the storage location.
    The downside (upside for some?) of the client is that it stores the whole blockchain.. (almost 15GB atm) Initial synchronisation takes a lot of time.. If you don't use it for some time, you'll have to synchronise again, which takes time (and CPU resources btw)..
    At the end of the day, the wallet is as secure as your machine is. No support for paper wallets / watch-only wallets / offline storage, transactions.. But for basic use - it works perfectly fine.
  2. Bitcoin Armory: A popular powerful client, runs "on top" of Bitcoin-QT, which means the blockchain is also stored on the local drive.. On top of that, the Armory client will also build a local database to manage it, which means it needs more storage on it's own.. (at the moment, that's an extra 16GB on top of the blockchain!). Also, the synchronisation status is not very helpful, just saying the % synchronised.. At least Bitcoin-QT states how many weeks/days you are behind, so you can somewhat estimate how soon the sync will work.
    The Armory client supports multiple wallets, compared to the official client, which can be stored separately. The wallets use (correct me if I'm wrong?) a deterministic key to generate the private keys, which means if you backup your wallet in cold storage - you can restore it at any point, and restore all the new addresses generated after the backup - a very useful feature. The Armory client has more advanced functionality like paper backups (described above), offline wallets and offline transactions, and a lot more.. Some features are missing, like importing watch-only addresses. You can though create a watch-only backup of a wallet, and import that on a different machine, but if you only have an address - not supported atm.
    The client seems rather powerful, but also feels a bit clunky and hard to use.. Some functionality is missing, and just strange (not all private key formats are supported.. even if most other clients have no problems with them)
  3. MultiBit: A lite bitcoin client, that doesn't store the whole blockchain locally. This makes it a lot easier to start using, even on a new machine. It will only synchronise a part of the blockchain that is relevant for a specific address, which means you save on both time and storage when using it, but it can be (potentially, but quite unlikely) compromised, if the only nodes it can see are rogue.
    It also supports multiple wallets, you can select where to store the wallet files, and they can be password protected as well. You can store them on a TrueCrypt volume, to secure it even more. The app is still relatively simple to use, while providing more functionality than just the basics.
    Compared to Armory and Bitcoin-QT, you can also create a portable installation, which can be stored on a USB key / True Crypt volume along with the key files.
  4. Electrum: This is one of the clients I've hardly used so far.. It has a full and a portable version! With the portable version I can store they keys where I want, and keep them secure as I see fit. As MultiBit, it doesn't store the full chain, but instead will use a server to keep and manage the blockchain. But nothing is stopping you from running your own electrum server and connecting to it, if you're worried.
    The client seems rather simple, but powerful at the same time. Same as Armory - it will create a seed that will be used to generate addresses. The nice thing is that it will generate multiple receiving addresses, and will also maintain change addresses, which (if I'm right) means that each transaction will not reuse the same address twice, unless you force it to. My only gripe so far with it is that it's the only client so far where you can't send to multiple addresses in one transaction, forcing only a single recipient per transaction.. I hope that'll change in the future :(

Help with old wallet.dat files

Hello guys,
I'm on a personal saga with those archives. I runned the -rescan on all of them, pluz downloaded the entire blockchain on bitcoin core. The one wallet that has balance is not showing the balance (or the address it contains) in it. I have the address.
As far as I can remember, I used armory instead of bitcoin core as a wallet, but it is strange, my memory may be failing me, since armory does not produce .dats, but .wallets.
Anyway, if use the command dumpprivkeys do I have a chance of opening it in another wallet (like electrum)?

350 bitcoins, encrypted wallet.dat deleted - lost forever?

I know I am insanely stupid. There is no need to be upset and yell that at me through the screen. I am happy to not be a gun owner because tonight I would have killed myself. I am posting this because countless others have posted similar stories whereby they learned important lessons the hard way due to lack of technical knowledge. In my case, the reason for this lack of knowledge was likely, ironically, the same reason I bought some bitcoins: drugs. I won't get into that. What I will post is where I went wrong, and where I'm at now.
Here's the full story: I had a securely encrypted wallet.dat with about 400 bitcoins on it that were purchased back at $10 or so. I pulled said wallet out of cold storage recently to cash money out of this wallet a few times to get some gift cards from gyft.com. I missed something ABSOLUTELY CRITICAL in my understanding of encrypted wallets.
When you send money, your wallet.dat file changes. You ABSOLUTELY MUST make new backups before deleting this file. Please don't do what I did and simply disregard this file after making changes on the blockchain...and then, on the same PC (sigh) proceed to reinstall StarCraft II when it fails to run due to Virtu MVP being retarded, ruining any shot at recovery (NONO #2: NEVER run bitcoin on your primary machine FOR ANY REASON).
I was a fool. Now I'm staring at TestDisk and File Manager in Parted Magic (linux boot disc) in total, absolute disbelief. Unless my data is stored within ".sst" files (never worked with these before and I can't figure out what they are with google, though it looks like fucking chrome shit because I leave it open all the time), which it may be, I don't know what to do. Maybe I'll try GetDataBack NTFS next. Maybe I can actually read filenames proper more effectively there? Does anyone have experience with this?
I have turned off the main PC and booted it up into parted magic so there is no data being written to the drive anymore. If there is ANY shot at this wallet.dat being recovered I am not screwing myself over any more now.
If anyone helps me out with this, I will compensate you generously. I am scared and lost. I never deserved bitcoin to begin with. If I can't get them back...well...enjoy the value appreciation, I guess, everyone. =( Such shame I have never felt; such guilt I may never feel again.
I have tried my old wallet.dat files repeatedly before coming to the realization that encrypted wallets change with each and every transaction...and the one backup I thought I made (moved, not copied) says it is corrupt.
It's easy to pretend what this feels like, but it's much worse in person. Educate yourselves and split up your wallets - now. Don't let this happen to you. If anyone is a kind soul and willing to help, feel free to PM me.
EDIT: I just recovered everything with an old wallet.dat. Tonight I went full tard. Luckily, this was a throwaway. I will never forget this...all of you came together to help, to suggest, to fucking CARE.
I WILL NOW TAKE TOMORROW OFF (sick day since I still feel sick as hell) TO FIX MY OTHER ISSUES WITH THE WALLET (aka putting all my eggs in one basket, keeping on a machine that is not specifically fucking made only for bitcoin, not using electrum/armory, not having my primary storage machine OFFLINE, etc.) All of you - ALL of you - are less selfish and less stupid than me. You should all feel amazing.

Need help with Armory

I re-installed Windows 8.1 Pro 64-bit on my computer and when I installed Bitcoin Core and Armory and restored my wallets, Armory is now reporting an incorrect balance.
I'm running Bitcoin Core v0.10.0 and Armory v0.93.1. Before the format, I was running one of the previous versions of Core and Armory v0.92.3. Armory only had a watching wallet for cold storage. I simply transferred my wallet.dat file and my *_.watchonly.wallet from my AppData folder. I've tried the rescan and rebuild option on Armory to no avail. Why is it still showing me a balance that is short? I can see the correct amount showing on the address on the blockchain.
Any help or advice that can be offered would be much appreciated.

Ever lose the password to your encrypted bitcoin wallet?

I wanted to give props to a man who really saved my ass. Dave from www.walletrecoveryservices.com. This weekend I was trying to access and send my wallet to my armory wallet in order to make a paper backup. low and behold I lost my fucking password. I wasn't happy, infact I spent about 3 days trying to figure out how to crack the password and I'm not exactly a technical creature.
I downloaded John The Ripper, ran atleast 40 hours of wordlist pregen possible passwords and got no where.
I was desperate, and I was scared. I took a big scary risk, and I sought professional help. Dave from that website I gave above was able to crack the password on my wallet.dat from bitcoin core and save me some bitcoins. It cost me 20 percent of my wallet, but that isn't nearly as bad as 100 percent. He is a trust worthy guy, and just trying to make some bitcoin. I can verify use of his service at my email address [email protected]. My only complaint is that I wish it was more like 10 - 15 percent of the wallet considering the cost of bitcoin now-a-days. Kinda scary for folks without a lot of income (but then again they probobly shouldn't be throwing money at bitcoin then)
Just wanted to give credit where credit was due. Dave from www.walletrecoveryservices.com saved my ass. Thanks Dave.

Oops. Forgot about a change address. Maybe lost coins. Possible to retrieve key?

I was doing some testing with some RPC calls tonight. I did some benchmarks, which included sending coins.
I then made a backup of my wallet.
I then did some testing, playing with features, adding some stuff, etc... including a final benchmark test sending .1 BTC to another wallet.
Ok, all is good. Shut down bitcoin, copy backup over the now-unneeded wallet - start bitcoin. Send the .2 I sent out back.
But I'm missing like .37 BTC. What the heck? I do a listtransactions and see I sent .37 to some address I dont know.
Oh. Crap. The change from the .1 I sent from the now deleted wallet.dat.
Since I have the original wallet that created that change address - and since it's a derivative of my wallet - can it be recreated? Or is that private key gone and I just learned a $234 lesson?
I know bitcoin Armory can create all addresses off the original backup - this wasnt Armory. It was bitcoind. Please someone tell me it can do that?
