Where can I import my wallet.dat? : Bitcoin

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.

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.

Bitcoin Qt -wallet problem and wallet.dat and blocks folder import..

I know I can find some talking about all this questions I am asking, but Im so scare to loose my coins I would like to have a instructions how-to-do-it to be sure..
Damn, the worst happened.. My laptop got so stuck I had to sweep it.. I did backup my bitcoin folder in c: driver (i dont if I need it?) and also I think I did backup my wallet just few days ago which is in time to my usb..
So first question: I have win 7. Pretty clean install. I can install bitcoin Qt, np but when I try to start it windows give a warning that "unexpected promblem appeared, shutting down the program". Everytime! Windows do not give any specific number or anything, or not even advice how to repair it. Just unknown problem and closing. Everytime. I did try to do like three times a new clean install.. (downloaded from web)
I think firewall and win defender is okeyh with it. (allowing).. I have avast antivirus..? Can it be the problem? I did have same wallet, same Os and same antivirus last time when this laptop worked and everything worked smoothly.. Not even one problem..
Also, the other question. If I have backup of my last blocks folder (14gb) can I use it? If yes, please tell me how. ELI5! :)
Main question: If I get this bitcoin-qt running, will the walled.dat import be as easy as I think. Just take my old copy and choose import wallet? So is there anything I should think before doing? This is my first time I need to use backup.
Cheers guys! I hope I will get stuff working soon and can again have some new coins!

How can I import multiple wallet.dat files into Bitcoin-Qt

Hi everyone.
I'm just getting back into Bitcoin seriously again and I have what is probably a stupid question.
I have a bunch of wallet.dat backups rather than private keys. I'm wondering how I can import/merge them into Bitcoin-Qt?

Why isn't there a Wallet.dat or private key import feature in bitcoin-qt?

This is what I am asking myself for two years now and I finally decided to ask. In addition to that: why not a paper wallet print and import feature (maybe webcam support)?
I now that there is a ton of other potential features and the development takes time and so on. But these here appear to be extremely essential since using bitcoin is in fact very risky without these simple precautions.
You want unskilled users to search for a folder that is not even visible on a fresh system? The people who cant find this folder are the ones who also make other mistakes and the ones who get their bitcoins stolen.

Was using bitcoin-qt on OSX, blockchain got corrupted and now it is impossibly big to re-download, what thin clients can I import my wallet.dat into?? OSX 10.7.5. I already tried electrum and looks like I'd have to build it from github, can't figure it out. please help.

Send help! is there a safe way I could download a torrent of the blockchain? i tried to reindex the blockchain (after my harddrive got unplugged while bitcoin-qt was running) and it looks like it would literally take a week of spinning my poor laptop fan balls out.
edit: wallet.dat is encrypted and safely backed up.

How can I import ("sweep?") my Bitcoin-Qt wallet.dat into my Mycelium or Trezor wallet?

Have some receiving addresses I don't want to use, even though I don't use the Qt wallet any more.

Can I import my wallet.dat file from Bitcoin-qt into Electrum or some other light-weight or online wallet?

I can't get the entire blockchain on my computer, but I have the wallet.dat file from Bitcoin-qt. I'm wondering if there is an online wallet or other light-weight wallet I can import the wallet.dat file into and send my bitcoin out to my electrum wallet.
I just need to get my bitcoin out of the bitcoin-qt client with nothing but the wallet.dat file.
I'm on a mac.

Importing Wallet.dat into Qt 4.8.3 Bitcoin v0.8.5-beta?

Any old timers here - is it as simple as replacing the default wallet.dat with the one you've got, and loading up the software? I've got a bunch of old wallet.dat files I wanted to look at again and I saved the version of QT from back in the day.
I seem to remember having to run an import command on the debug screen if the dat file was encrypted with a passphrase. Am I remembering correctly? If so do you know the command?
Imprt privky or something like that. Maybe that was only for importing paper wallets into QT .....

When importing a wallet.dat file from an encrypted Bitcoin-QT to blockchain, does the password of bitcoin-qt become the password on the blockchain wallet?

What I'm trying to do is move my coins from bitcoin-qt to my Electrum wallet because the block database got corrupted and I'm tired of having to always rebuild it when this happens.
I'm quite nervous about moving my coins around like this without knowing exactly what I'm getting into. Is there a better way of doing this?

Old Mining Contract - Reddit Sleuths Needed

Dear Famed Reddit Users,
I apologise in advance if I waste anybody's time here however I need suggestions on whether I can establish if I received a payment from a mining contract I took out in 2013.
Back in July 2013 I bough a Bitcoin mining contract from a website called bitcoinfrenzy.com. I paid $49 for "1 GH/s Bitcoin Mining Power – 1 Year Contract (#1GH001) "
This website no longer exists and it may have been a scam as I was quite flush back then so I bought the contract and thought no more of it.
After the initial purchase email in July 2013 I heard no more until November 2013.
13 November 2013 - Newsletter email stating: "After a long struggle Mining is started for July to till date customers . The order status for all paid orders will be updated within 48 Hours . And we will update"
16 November 2013 I have an email stating that the order had been processed
22 November 2013 Email stating that payouts have been made from wallet address 1LKpQYvMCyfa5AwD8KrDknhjGfP87xWsVN
No further emails after this point.
When I check the blockchain for this address I can see coins were sent to multiple addresses on 22 November 2013.
I do not know what wallet address I provided to bitcoinfrenzy for receipt of any payout.
I did create a wallet on blockchain in May 2013. I have accessed this wallet and there is no transaction history showing.
I have an old version of bitcoin-qt on an old hard disk drive which has a wallet.dat file created April 2013. I have been unsuccessful when trying to load this wallet.
I have all hard drives/laptops from 2013 and since.
Views on: Am I wasting my time here? I s there anything else I can search my hard drives for? How can I access my old wallet.dat (and none of the results I've found while searching have worked).
NB if one of the receiving addresses from the payout belongs to me the coins will be unspent, there will be no transactions after 22 November 2013 and there may not be any other transactions prior to this.
Thanks for reading

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

weird behavior of electrum+bitcoin-qt

past week installed the new plugin that allow me to connect my electrum wallet to bitcoin-core, i use a hardware wallet and worked like a charm.
Then today was updating the node and used bitcoin-qt instead of bitcoind and when was waiting suddendly i see some text in the gui where it says "recent transactions", and a lot of transactions where there.
Then was like WTF happened here, someone stole my btc?, or installed a compromised version of electrum(i use archlinux and install from the repos). Why some transactions where there, i neved imported my wallet to bitcoin-gui.
Inmediately deleted the wallet.dat and did the same in electrum, but my question is:
Was something imported into bitcoin-qt?, all my history was redeable from the gui, i never imported into bitcoin-qt, and as far i know the seed never leave the hardware wallet.
This is normal?, at least all my funds are still there but im really worried.
PS: everything happened with my hardwallet unplugged.
TL:DR: Connected my cold wallet to electrum(connected to bitcoind) past week, never to bitcoin-qt, today opened bitcoin-qt and all my history of transactions from my cold wallet(unplugged) was there(bitcoin-qt), is this normal?.
