Electrum doesnt reconigze my wallet.dat (from bitcoin QT) what to do?
Guys, i downloaded electrum on my laptop and tried to import my old wallet.dat from (bitcoin QT) 2017. But Electrum doesn't recognize the file. Anyone know how to solve this f*cking problem. Perhaps any other suggestions ?
How do you import a Bitcoin Core (QT)-made wallet.dat file into another wallet?
So I have a wallet.dat made a while ago and wanted to check what was in it, problem is it was made in the bitcoin core QT client, which I can't even load up because it occasionally freezes and usually won't even sync up, at an absurdly slow rate. When I replace that wallet file into the default data directory, and start bitcoin-qt.exe with the -rescan command, it just starts but no addresses show up in my wallet file and i noticed the wallet.dat file size changes when the bitcoin core client starts up, seemingly modifying something to make it slightly bigger, don't know why. How do I check this wallet.dat? I tried importing it into the latest electrum 3.2.3 wallet and it won't accept it.
Mined some coins around 2012 on bitcoin-qt, how do I sync my wallet.dat?
As titled. I haven't kept up as life had consumed me, but the last couple months I had a new bitcoin-qt synced up. My old app would not even sync properly, but still kept on my harddrive, already been backed up. Any advice?
If I backup my wallet.dat can I reinstall bitcoin QT without losing BTC?
Trying to get a payment. Bitcoin QT stuck synchronizing. Last block data is from 302 days ago. Any tips welcome. [UPDATE] WHAT I DID TO SOLVE THIS PROBLEM, KIND OF, AKA, A WORKAROUND. Backstory: This was also my first bitcoin transaction ever. & I'm not even mildly a computer genius. 1 Backed up my wallet.dat to a file on my desktop so I didn't lose it. (I was fucking scared of losing it) 2 Uploaded wallet.dat to : https://blockchain.info/wallet/ --- (since this was my first transaction, it's not like I had a lot of coins in my wallet so I figured I'll upload it here, cash in what I will, and move the rest someplace more secure) 3 Made a coinbase account. 4 Linked it to bank account with instant verification. (pretty neat) 5 Copied generated on coinbase (they don't explain it but coinbase is also sort of a 'wallet') 6 Pasted that address into the field on the page for sending coins on the Blockchain Wallet Page. Hit send. HELD BREATH CUZ I SENT A BUNCH OF MONEY THROUGH SPACE. The computer made a weird noise, like a DOS-y sort of beep. 7 Refreshed my Coinbase wallet and TA-DAA, they were there!!! 8 Waited while the transaction was 'pending' for a little under hour. (This is normal) 9 Sent to bank account. =] =] =]
(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:
"sweeping" the funds from the private keys of the old, unencrypted wallet into another wallet, or
doing a normal "spend" from the private keys of the old, unencrypted wallet (However, if the old unencrypted and the new encrypted wallets now contain different pools of addresses, then I imagine that this spend would invalidate the new, encrypted wallet - because any change from the spend would be sent to a "change address" from among those in the old, unencrypted wallet - and so this amount of change would be missing from the new encrypted wallet, right?).
(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!
How to get the wallet.dat file and import it into the Bitcoin QT Client
Go to MonteCrypto Game, click properties, then go to local files. Follow this directory: C:\Program Files (x86)\Steam\steamapps\common\MonteCrypto\CryptoChallenge\Content\CryptoChallenge\Datamaps I can confirm the wallet.dat file IS the one with the bitcoin. I imported it to my bitcoin qt client and the public key matches. Now I already found 4/24 so I'm feeling good, but I know for a fact you need all 24 words. Brute forcing with just 23 would take decades.
wallet.dat files with Bitcoin-QT - can they be cut/paste/renamed copied like a normal file, and then put back into QT later?
Here's what I did:
Receive 2.2 BTC into default QT address. Read about how important to encrypt your wallet, then want to get at least 2BTC 'safe', leave .2 for shopping/tips etc Sync - shut down QT. Rename wallet.dat to wallet-old.dat Open QT, and it makes new wallet. Encrypt the wallet, add 4 public key - copy them to a doc. Sync - shut down QT. Rename the new wallet-> Savings.dat, and move to USB offline. Rename the old wallet back to wallet.dat. Send 0.5 BTC to each address in the new, offline wallet.
Is this ok? I have checked the new addresses at Blockchain for the 0.5's and they are there. But I just heard about change addresses, and got a bit spooked, especially about using the first wallet, which still has the smaller amount of BTC. Can I still receive here or do I need to make a new one? Will I be able to send the 0.5's out from QT if I rename the new wallet back to wallet.dat at some point in the future? Is it safe to send more BTC into this offline wallet? Can i back it up to multiple places and be sure i can just replace one of these backups into QT, and send the 2BTC back out again - what will happen to all the OTHER backups if I do? I did try to read about this but mostly saw stuff on paper wallets. I don't want to confuse the issue with paper wallets. Questions about those once I've tried it... Many thanks
