New to Bitcoin? Confused? Need help? You've come to the right place.
Bitcoin is an internet based decentralised currency. Similarly to Bittorrent, but Bitcoin uses a public ledger called the blockchain to record who has sent and received money. It's very new, and for many very confusing. BitcoinHelp aims to rectify this. Whether it be explaining how it works, how to use it, how to buy Bitcoins, how to integrate Bitcoins into your business. Sharing your successes as well as failures in order to help others is also gladly received. Ask away!
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?.
Hi - sorry I'f this has been asked before but I've trolled the Interwebs and cant find a suitable answer. I guess the question is not really that Jaxx specific but here goes *So you have made a note of your private keys and obviously your public keys from Jaxx (or other wallet) and you want to import that wallet into another wallet as your not sure that Jaxx is secure anymore. Can you simply import or sweep the wallet into another online wallet such as electrum, bitcoin-QT, blockchain.info, etc? * Without transferring into paper wallet.

''' THAT'S RIDICULOUS!!! YOU DON'T NEED TO RUN AN ELECTRONEUM SERVER TO USE THE CORE WALLET/NODE. AND THE QT CORE IS JUST AS SIMPLE AS ELECTRUM (I THINK EASIER) PLUS IT ALLOWS FOR SO MUCH MORE FLEXIBILITY SHOULD YOU WISH TO DELVE INTO THE ADVANCED FEATURES. THE ONLY CAVEAT IS THE TIME TO SYNC AND THE SPACE REQUIRED. BUT IF EVERYONE SAID "FUCK THAT I'M NOT WASTING 250GB AND RUNNING MY WALLET 24/7 TO GET/KEEP IT SYNCED, OR WAITING FOR IT TO RESYNC EVERY TIME I WANT TO SPEND" THEN BITCOIN WOULD HAVE NO DECENTRALIZATION LEFT (WHICH HONESTLY IF YOU LOOK AT THE DECREASE IN NODES RUNNING, YOU'D SEE THAT'S WHAT'S HAPPENING.) ACTUALLY BELIEVE IN BITCOIN? THEN PUT UP OR SHUT UP! Just run the core node! A.K.A. the full wallet. You don't need to set up an electrum server. That would only be if you wanted to contribute to the electrum network by serving as a public server. But honestly, it's much better to run the core in terms of decentralization anyway. It requires no technical know-how! Only a couple hundred gigs of hard drive space and a week of letting the blockchain sync (for an average PC that's a few years old). And you can "prune" the node after it finishes syncing so you'll only need ~10GB of space when all's said and done (although you must have at least 250GB free to properly sync). Just download the official qt for whatever flavor of bitcoin/altcoin you need and run the installer. It's honestly just as easy as electrum- you just need to sync first before you can spend. Importing the xpriv's from your old electrum wallet is easy...
Open debug window (help>debug window)
Click on the 'command line' tab.
Type `importprivkey ' (no <>).
*To get your xpriv (AKA private keys, out of electrum, right mouse button on all your addresses with funds and select show private key. Do this for each private key, importing one by one and you're done. If the repetition is too much for you. Just send all your coins to a single address first. *NOTE THAT YOU MAY ALSO CHOOSE TO SIMPLY GENERATE A NEW ADDRESS FROM THE GUI IN THE CORE NODE AND SEND YOUR COINS FROM ELECTRUM TO YOUR NEW NODE. YOU MAY DO THIS AS SOON AS YOU'RE DONE SETTING UP THE CLIENT- HOWEVER YOU WON'T SEE THE TRANSACTION COME THRU UNTIL YOUR NODE SYNCS SO DON'T BE WORRIED ABOUT THAT ASPECT * It'll take 7 minutes to set up and then you will not only be running securely, able to use any address format you want (including the segwit P2SH keys everyone should use for BTC), your txns and IP aren't logged by a random server, and you're helping maintain a Distributed Blockchain. Forward the default port 8333 in your router NAT mapping and make yourself connectable to actually make a difference. You'll probably notice your transactions confirm a tad bit faster during times of congestion as well. ''' Context Link Go1dfish undelete link unreddit undelete link Author: Nycmdthroaway
In bitcoin-qt, I used dumpprivkey, and now have set of strgins which start with either L or K. How can I load it to Electrum? Or is it not possible at all? I'm asking mostly because there is no bitcoin-qt for Vivid (ubuntu) yet, and from what I understand - Electrum is supopsed to be faster, and don't require local copy of whole blockchain.
Hi guys, I need to create a raw transaction and sing it to broadcast to the network with bitcoin-qt, the bech32 address was created with electrum, If try to sign it, bitcoin-qt gives a private key error, any clue?
I was asking on /bitcoin how to access my Bitcoin core QT wallet without downloading the ~160Gb blockchain and was advised I can import the Bitcoin core QT wallet into Electrum. Can I first confirm that this can be done? I also would like to know how to go about it? I was also told that since I have had the coins for several years thatI should be able to claim bitcoin cash of about 10%? Can I do this and how would I go about this? Does importing the wallet into Electrum affect this in any way? I also saw this: https://www.reddit.com/Electrum/comments/7ighpo/what_is_a_watch_only_bitcoin_address/ Does this mean that I can create a Electrum wallet, just put in my public key and check my balance?
Bitcoin-QT, Electrum, MultiBit, Blockchain- My Wallet, Cold-Storage? What do you recommend someone that has never owned bitcoins?
I'd appreciate some expert knowledge, as all the information I read doesn't justify one service over the other. I'd like personal tales and relatable comments. I've read the Getting Started guide multiple times. Personally leaning towards having 'cold-storage' and putting a USB drive in my sock drawer at home. Please give me serious suggestions and ideas.
Transferring private keys from Bitcoin-qt to Electrum wallet, but amount is wrong?
So basically I started out with Bitcoin-qt years ago, but it's too cumbersome now with me needing the giant blockchain downloaded. Anyway, I decided to try Electrum. I read how to extract my private keys from the bitcoin-qt wallet address, and import them into my newly created Electrum wallet. Bitcoin-qt showed I had 9 receive addresses, and after importing all 9 into Electrum the amount isn't the same. While it's not a gigantic difference, Electrum shows roughly 0.015 BTC less than Bitcoin-qt. When I check all of the address on blockchain.info and add them all up it comes out to what Electrum is showing. Does anybody know why Bitcoin-qt is showing more (which should be correct from all my previous transactions), and how to get the small remaining amount imported into Electrum without just transferring the balance (thus incurring a fee)?
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 transfer all my BitCoins from Bitcoin-QT to Electrum without paying the transaction fee?
I have Bitcoin-QT, however I absolutely HATE the UI. I wanted to switch to Electrum. However, upon trying to send all my 0.1298 bitcoins to Electrum, I realised I must pay a transaction fee. However, being as short as I am on Bitcoin, I wouldn't mind taking a harder method of transferring Bitcoins as long as I don't get feed as much (and preferably no fee). How can I do this? Thanks
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.
Have Bitcoin Qt, no more HD space, want to switch to Electrum...
I have bitcoins stored on my laptop and I use Bitcoin Qt. However, since I have little hard drive space left, I haven't been able to let the app download the blockchain and sync up. I want to have my bitcoins in a wallet on Electrum, which apparently is quicker and easier as it doesn't download the entire blockchain. How can I go about transferring my bitcoins from Bitcoin Qt to a new account with Electrum? Do I actually have to wait for Qt to sync up or can I transfer immediately? Is there an alternative method using the wallet.dat file? Thanks guys.
