where is this = to the %appdata%/MultiBit directory=  to copy and paste to?

  Thank You for all your Help!!

Appdata is a folder that's normally hidden by windows. Multibit wallets put a folder inside the hidden appdata folder. You can open it using these instructions.



Click the windows start button, then copy and paste the line of text below into the search box that appears, then press the enter key to open the hidden folder containing your multibit wallet files.

%appdata%\Multibit

This is what your search box should look like after you have copied and pasted the line above into it.

If you have a wallet.dat you can open it with an offline bitcoin core, then use the instructions in the quote to export private keys from it and import them into an electrum wallet. Electrum can give you almost instant access to your coins.

Click file, then receiving addresses. Find the address you sent coins to in the window that opens, right click it, and select copy address. Close the addresses window.

Click help, then debug window.

In the debug window that opens click console.

In the text box at the bottom of the window type

dumpprivkey yourAddress

where yourAddress is the address you sent coins to and copied earlier.

Press your enter key.

The private key for that address should appear in the console window. Copy it.

This is an example private key.

L48toSntMVhC2az4KAQCWscrQGfPbT55yCgzM5cmx9Ao69pTdwrq

Download and install electrum.

https://electrum.org/#download

Import your private key into it using these instructions.

http://docs.electrum.org/en/latest/faq.html#can-i-import-private-keys-from-other-bitcoin-clients

Afterwards your coins should be spendable.

Thankyou again. Yes if I run it it will be on the cold storage laptop with no internet connection. So there is one virus or malware on that program?

It's probably a false positive, but you can never be 100% sure about anything. Even if a virustotal scan says something is clean it doesn't mean it is. It's always best to run something that deals with unencrypted private keys in a virtual machine. Better safe than sorry.
2125  Bitcoin / Bitcoin Technical Support / Re: Creating new paper wallet and testing it. on: June 15, 2017, 12:17:06 AM
Thankyou so very much for your thoughtful feedback.

 Yes my fear is to send the little BTC I have into oblivion or into a wallet I cannot recover.

 So from what I can see...if I have the 51 character base58 private key stashed away with the encrypted wallet...and let us say the decryption fails i can recover my funds right? I have tried the paper decryption with Mycelium but you have to be online and the test worked...but i do not dare do it on my cold storage paper wallet

   Or i can create a brain wallet with seed words up to to 24 words. Probably that would be best. Please tell me your thoughts on this and thanks.

After searching a bit further I found this page on the bitcoin github.

https://github.com/bitcoin/bips/blob/master/bip-0038.mediawiki

It links to this software that can decrypt BIP38 keys.

https://casascius.com/btcaddress-alpha.zip

I tested it on a key encrypted and generated by bitcoinpaperwallet.com, and it decrypted it OK.

Don't run that software anywhere apart from in an offline environment isolated from your regular operating system. Ideally run it in an offline virtual machine.

A virustotal scan gave one positive result out of 56 results.

I don't know how accurate this story is, but if China's Sichuan Province really is banning Bitcoin mining maybe that's another factor in the dip. It's a new twist, China "bans" Bitcoin mining instead of China "bans" Bitcoin.

that's good news isn't it? chinese influence on bitcoin has been almost nothing but total poison, from the exchanges to the centralization of mining. the sooner they're gone the better.

Maybe, but I heard the China "bans" Bitcoin story too often to believe it any more. Likewise, I'm very sceptical about the China "bans" Bitcoin mining story.

You can try this client side javascript based generator (bitaddress.org):

https://github.com/pointbiz/bitaddress.org
https://bitcointalk.org/index.php?topic=43496.0 [ANN]

Run it offline and put in the private key to validate the resulting address, and you should be good to go.

Hi I looked closely at your post again and have to tell you that is the paper wallet generator I used. Is there another?

Download and install electrum. You can use it offline to verify a private key and address match.

https://electrum.org/#download

Use these instructions to import a private key into it and it will show you the matching address.

http://docs.electrum.org/en/latest/faq.html#can-i-import-private-keys-from-other-bitcoin-clients

Ok...I tried Electrum...it works fine if you use the 51 character base58 private key....but it does not recognize the PRIVATE KEY BIP38 FORMAT...i need to try that to see if password decrypts it and then show private and public key correctly

Thanks

I can't find any 100% trustable well known wallets that can both decrypt bip38 keys and display the decrypted results. However if you search github for bip38 plenty of results come up. Don't blame me if any of them are malicious and steal your Bitcoins. If you try any of them only do it in a secure isolated offline environment like in a virtual machine.

You are wise to be cautious. There was a bug in bitcoinpaperwallet and bitaddress that made wallets created in Safari 6.05 undecryptable in any other browser. This is the bitcoinpaperwallet dev's announcement of it.



Hi, bitcoinpaperwallet.com author here.

Over on GitHub, artiomchi and I have been working on adding BIP38 support. As some of you know, I've been extremely cautious/slow/dragging my heels with BIP38 implementation since it's relatively new and not especially well supported by wallet software and services.

During testing, we uncovered an issue with Safari version 6.05 in which BIP38 encrypted wallets end up with a different (essentially wrong and invalid) "6P..." private key. The only way to decode one of these wallets is to use Safari 6.05 for decryption as well. If you upgrade your browser after printing a BIP38 wallet using Safari 6.05, you won't be able to decrypt it unless you find some way to downgrade back to 6.05.

This is a problem endemic to most (all?) services implementing BIP38 via Javascript -- bitaddress.org, etc. It doesn't impact https://bitcoinpaperwallet.com because we haven't deployed BIP38 (yet).

As a preliminary step until a fix is in place, I recommend:

1. Do not use Safari version 6 to make any new BIP38 wallets

2. If you already used Safari version 6 to make BIP38 wallets, decrypt those paper wallets right now (using Safari 6, nothing else will work) and keep an unencrypted paper backup somewhere safe. Consider making new BIP38 wallets using Chrome or Firefox, and use them to receive funds from your Safari 6-encrypted wallets. Once you're sure your safari-6 BIP38 encrypted wallets are empty, discard.

Here are the relevant threads if you want to dig into the nitty gritty, or contribute your own tests/validation:

https://github.com/cantonbecker/bitcoinpaperwallet/pull/6
https://github.com/pointbiz/bitaddress.org/issues/56
https://github.com/mannkind/bit2factor.org/issues/2

Huge thanks to /u/artiomchi for his excellent work bringing BIP38 to bitcoinpaperwallet.com and for helping to narrow down this possibly alarming issue.


Bitcoinpaperwallet acknowledges that few wallets can import BIP38 keys and can only recommend using its own paper wallet page for decryption.


https://bitcoinpaperwallet.com/wallet-tutorial-add-withdraw-funds/

Quote
Important note for BIP38-encrypted paper wallets

Not many bitcoin wallet applications or web services are able to directly import BIP38 password-protected private keys. In this case, you will have to use the "Validate" feature on the generator to extract the unencrypted Wallet Import Format (WIF) key as an intermediate step before sweeping the balance.

The Fed raised rates today. So there's that.

No more free ride for hot money?

It could be a combination of factors. Bitfinex is lower than stamp and seems to be leading the dip. Someone's dumping coins on finex.

Wouldn't be surprised to see a lot of hot money dumping btc to run and start accumulating that IOTA crap, whatever the hell that is.  They'll accumulate at 0.50c for a while, then start pumping it.

Altlandia: what a complete farce of a shitshow market that is.

i was offline since the last dump, when i bought some at 2260 EURO and now that i am back i check we are only 45 euro up from that...
pretty boring.. why we not pass 3000 euros already? why those dumps?

Peak euphoria is the problem: reading this board makes you think it's only a matter of time until we reach 4000+ BTC's, while nearly no one seems to be taking into account that the market may be satiated already.  BTC has bounced back twice now from about the same price level, and that is a strong signal after a two-and-a-half month long rally.

Although I haven't been following the latest ICOs someone claimed some of them are raising huge amounts. When the devs behind them dump the Bitcoins they collected it might suppress the price for a while.

Maybe some dev just dumped his ICO coins. If that's what happened the market will probably soon absorb the coins and the price will go back up afterwards.


stop saying "ICO" this was a poloniex creative spin on "IPO" because ipos require registration duhhh lol Cool

But so many ICO investors gamblers got ripped off over the years that "ICO" now means initial crapcoin offering.

After a bit more searching I noticed the USA gubberment has raised the interest rates. Maybe that's got something to do with the dip too.

2136  Bitcoin / Wallet software / Re: Who experienced used Jaxx wallet? would like to ask something. on: June 13, 2017, 08:26:24 PM



It is not that recommended to use Jaxx wallet. If you want a good wallet for security and ease of use everyday I suggest you go with Electrum wallet both in desktop and mobile. Make sure to safeguard the seed extremely well as that is all you need to restore bitcoins if you format your PC for example or wipe your phone. Lately Jaxx wallet is using some high fees and many people are complaining about that.

In Electrum I paid yesterday only 0.0009 btc fee for sending a transaction of 0.08 btc meaning it will not do games in the fees, you are in full control. Of course I only had this amount from 1 input. If you have many inputs even in Electrum you pay high fees.
Honestly my plan is to hold other altcoin and bitcoin both in one wallet i heard that jaxx are good choice if you want to hold altcoin and bitcoin in the same place.
Well looks like its not a good idea to choose Jaxx maybe i need to look for other that can handle any cryptocurrency.


Using Jaxx to hold altcoins and bitcoins in the same wallet puts all your coins at the risk of being stolen. Hackers have found a vulnerability in Jaxx and are using it to steal people's coins.



Reports are surfacing of a ‘vulnerability’ in Jaxx wallet leading to at least $400,000 customer funds being stolen.

A report on the insufficient wallet backup phrase storage methods this weekend has now updated to include reports that hackers are already exploiting the problem to steal cryptocurrency from users.



After you read the whole article[1], you will come up with the decision of not using this wallet again (most likely). Basically, they have no plans to alter or change the security setup of their wallet. I'd recommend everyone to either stop using this wallet or simply stop storing large amounts.

2137  Bitcoin / Electrum / Re: Updating Air Gapped Electrum Cold Storage (updating to 2.8 question) on: June 13, 2017, 02:23:01 PM
You don't need scripts to sign transactions using the latest version of electrum, it does it for you.

Use the latest version of electrum on your offline cold storage computer, and choose its option to restore a wallet from your seed wallet words, and leave the password field blank. If you open the wallet file it creates you should be able to find the wallet's master public key

Use the latest version of electrum on your online computer, and choose its option to create/restore a new wallet. Select "standard wallet", then select "use public or private keys". You should see this window where you can input your master public key (xpub).



After your watching only wallet's created when you want to spend coins do it as normal, but click the preview button, then either click the save button to save the unsigned transaction as a file, or click the button with the QR code icon to get the unsigned transaction as a QR code.

Transfer the unsigned transaction to your offline ,machine, click tools, then load transaction and select the file or QR code.

Sign the transaction offline, then repeat the process to save the signed transaction as a file, or QR code. Transfer the signed transaction to your online machine, click tools, load transaction, then click the broadcast button.

I haven't yet tested these instructions. If they don't work try creating a new online wallet using the addresses from your cold wallet as in the screenshot.



Note: reading QR codes doesn't work in the latest windows version of electrum, but works in the linux version.

If you formatted your hard drive then don't ever boot from it again. Running an operating system on it could erase any traces left of your Bitcoins. Pay a professional data recovery company to attempt getting your Bitcoins back if you did a full format on it.

If you did a quick format on your hard drive then this post might help.

https://bitcointalk.org/index.php?topic=1961924.msg19522772#msg19522772

If you haven't formatted your hard drive and didn't delete your Bitcoin wallet files then try these instructions.

Click the windows start button, then copy and paste the line of text below into the search box that appears, then press the enter key to open the hidden folder containing your Bitcoin wallet.dat file.

%appdata%\Bitcoin

This is what your search box should look like after you have copied and pasted the line above into it.



Inside the folder that opens there should be a file called wallet that ends with the extension ".dat". If you find such a  file you can probably recover your Bitcoins from it, provided it's not corrupted.

I'm switching to trading on Bitstamp, where they did the same verification in just a few days.

2140  Bitcoin / Bitcoin Technical Support / Re: Lost bitcoins. on: June 12, 2017, 09:56:22 PM
Did you have the quick format option checked when you formatted your drive, or did you do a full format? If you had the quick format option checked there might be a chance you could recover some coins yourself. If you did a full format I would pay a professional data recovery company to try recovering your coins.

Don't boot from that drive. If you continue running the installed operating system it might overwrite your wallet.dat data.

If you know how to use a hex editor you could try scanning your drive for this sequence of bytes: 01 03 6B 65 79 41 04.

That sequence often occurs in a wallet.dat file about 180 bytes before a private key. If you look forward 180 bytes and can find the byte sequence 04 20 then it's likely a private key is the next the thirty-two bytes.

If you find a private key you can change it to a common format by pasting the thirty-two bytes into an offline copy of this webpage.

https://www.bitaddress.org/

This is an example of the 32 bytes of a private key in notepad.

Quote






This is the private key copied from notepad and pasted into an offline copy of the bitaddress website. Click the view details button to get the private key converted to normal formats.







There's a more detailed explanation of the byte sequences to search for in this quote.

I have been doing some tinkering around, thinking about other people's wallet disasters, and believe I have come to the following conclusion...

If you have lost your wallet.dat for whatever reason (deleted it, formatted your drive, file corruption, etc.) it's possible that it may still be lurking on your computer.  If so, recovery is no longer purely theoretical.  With a little knowledge of what to search for, you can use a hex editor to potentially find usable remnants of your wallet.dat file and get back your bitcoins, even if the original file isn't fully recoverable.

So here goes...

If you can use a hex-editor to do a sector-by-sector search/edit on your entire hard drive, then search your entire hard drive for occurrences of the following byte sequence:

01 03 6B 65 79 41 04...........

the middle four of these bytes represent the string "keyA" in ASCII.

Each time this byte sequence occurs, a Bitcoin private key is probably stored nearby, about 180 bytes later.  The 32-byte private key is the only thing you need to recover your bitcoins!... as long as you find the right one(s).

Approximately 180 bytes after this sequence, you may find the byte sequence 04 20 (hex).  These two bytes seem to precede every private key (the 0x20 suggests a length of 32 bytes).  If you find this sequence, the thirty-two bytes that come after 04 20 are the private key representing a Bitcoin address and might be the private key that recovers some of your lost bitcoins!  Your wallet will have numerous private keys (at least one hundred, due to the pre-allocation of keys)... get as many as you can find.  Carefully search the sectors adjacent to any sector containing the "keyA" sequence above.  Then yell for help!  (But don't share the private keys in public, unless you want to give away your wallet.)

An example of a hex editor that can scan an entire disk volume for specific byte sequences for Windows is WinHex.  In WinHex, use Tools, Open Disk (F9), and choose the disk you want to scan.  Scanning a full disk can take hours.  WinHex must "run as administrator" to be able to scan a physical disk.  Someone please recommend a good way to do this in Linux, preferably with a known Live CD, if possible.  Also, any time you are scanning a disk for potentially lost data, you should NEVER boot the disk you're searching - always boot from another disk and install the target disk as secondary.
