2021  Bitcoin / Electrum / Re: Help recovering wallet on: June 30, 2017, 06:25:14 PM
I apologize in advance for my lack of knowledge with Electrum. Late 2015 I created a wallet and deposited some BTC. I have a piece of paper
with the seed phrase but no 'password' as it asks me for now but I do have a PIN code. I have tried all other passwords I can think of/have
written down but none seem to work. Tried restoring from seed and that doesn't work either(/unsure if doing this part correctly). I'm sure
at some point I uninstalled Electrum and re-installed recently, does it have something to do with an older version? Thanks
Is it a wallet with 2 factor authentication?
Maybe the pin is for 2fa that is why its asking.. if you added a email for 2fa you can receive your 2fa in your email..
if still not working it is different issue never had that issue before..
But I think you can use your electrum seed in blockchain to recover bitcoin.

I will look into these suggestions. I'm at work but will try later. I don't understand how I still have this 'default wallet' after reinstalling.

It's probably because electrum puts its wallet files in a folder that's hidden in windows, and when you uninstall electrum that folder doesn't get deleted. When you install a new version of electrum it looks in that folder, finds the old wallet file and opens it.

Try downloading and installing the portable version of electrum. That doesn't put its wallet files in the folder that's hidden in windows. It puts them into the same folder it's run from.

https://electrum.org/#download

So I've installed the portable version and restored from the seed I have on paper and I dont believe it but it has worked! Thank you so much I have been trying to figure this out
for ages. Odd how this worked but I cant complain.


It's probably because there is a wallet file in a hidden windows folder. If you want to look inside the hidden folder then follow the instructions in the quote. A folder should open afterwards, and somewhere inside it there should be a file named default_wallet that was causing the problem.

The portable version of electrum doesn't look at that folder, but the install-able version does.

Copy this line of text.

%appdata%\Electrum

Click the windows start button, then paste the line of text into the search box that appears, then press your enter key to open the hidden folder.

This is what the search box should look like after pasting the line of text into it.

You could import your private key into the electrum wallet. These instructions explain how to do it.

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

By default electrum uses a seed phrase to create new wallets, but you can choose to create a new one by importing private keys instead. The main difference is you need to make backups of your private keys or the wallet file if you choose to import keys. If you use a seed you only need to backup the seed.

You can download electrum here.

2023  Bitcoin / Electrum / Re: Cold Storage after the default 20 Addresses? on: June 30, 2017, 06:09:16 PM
I don't think it matters if you can't see more than the default 20 addresses in your cold storage wallet. I guess you should be able to create an unsigned transaction from an address over that limit in your online wallet,then sign it with your offline wallet,

As a test you could try signing a message from an address in your cold wallet that's over its default 20 addresses limit. If it can sign a message from an address that's not showing then it should also be able to sign a transaction from it.
2024  Bitcoin / Mycelium / Re: Custom Fee on: June 30, 2017, 05:52:20 PM
Maybe setting custom fees is too risky, many users will ignore the warning and mess things up by sending txs with ridiculous fees like 50 satoshi fee or so (not per byte, but in total  Wink). And then complain about their tx never coming through.



If users were made to jump through a lot of hoops to get to a custom fee setting window it's unlikely inexperienced users would use it. The devs could also add some code that compares a custom fee with the dynamic fee and warns about excessively high or low fees when someone tries to send a transaction. Other wallets already implement such warnings.

Thanks for being prepared to put a lot of effort into moderating this.

I think we are going sideways this week, range bound between £2500 and $2600. I can't see any significant walls on stamp, which usually indicates nobody's sure which way it will go.

2026  Economy / Speculation / Re: Wall Observer: BTC/USD Price Tracking and Discussion 2.0 (Unmoderated) on: June 30, 2017, 05:13:09 PM

Anyway, on the actual thread: The price seems to be wobbling in nowhere's land. The uncertainty is in the air. Everyone is just watching, nobody has no clue what is going to happen. The outcome is anyone's guess. Let's just hope there's no hardfork or anything stupid because the crash could be epic.

I think it might stay between $2500 and $2600 this week because of the uncertainty. When it reached $3000 everyone thought it couldn't go higher and dumped. However when it went close to $2000 everyone thought it couldn't go lower and bought back. It will probably go sideways for a week while everyone waits to see which way it's going to go.

Later this year I think it will go over $10000 and today's price will seem cheap.

You don't need the password to recover from seed. I think there was a change in the recent electrum wallet versions that makes them ask for a password for a new wallet by default.

If you leave the password field blank when creating a "restore from seed" wallet it shouldn't ask for a password when you use it.
2029  Economy / Speculation / Re: WALL Observer : Death and Rebirth of Prices, Crashes and Lifes. on: June 29, 2017, 11:06:45 PM
Looking at the 6h. Price needs to break 2600 here forcefully and with volume, otherwise will bounce lower.

Ok boys, let's get on with speculation. This happened exactly as I said it would, price failed to bust through 2600 and is now moving lower.

Anyone wanna speculate where the price goes next?

I speculate  that 2600 will be broken tomorrow and then a $50 dollar jump within 24 hours

I speculate that the price will ping pong between $2500 and $2600 for the whole of the next week. After all the volatility we are due some stability.
2030  Bitcoin / Bitcoin Technical Support / Re: How to recover btc after windows reinstall on: June 29, 2017, 10:08:55 PM

Sorry to bug you again but when i start hex editor, the drive letter doesn't appear, only drive D. Thanks.

Are you trying to scan an external drive or your internal one with your operating system running on it? It should already be able to see all your external hard drives.

By default it only scans external drives like the type you plug into a USB port. I only recommend running it inside a vmware or virtual box  virtual machine in case there is anything malicious hidden in it. I wouldn't ever risk searching for private keys in plain text while running it on my internet connected operating system.

If you can't see a particular external hard drive with it then you could try running it with administrative privileges in windows, or as root in linux. However if you risk doing that you must definitely run the hex editor inside a virtual machine for safety. If you give it administrative privileges or make it root then you are giving it control of your operating system, and that's a big security risk. Also, it will be able to open your drive running your operating system which will probably show as physicaldrive0. If you edit the hex on that drive you could crash your operating system.
2031  Bitcoin / Electrum / Re: Sent adresses in Electrum? on: June 27, 2017, 09:20:24 PM
If you right click any address with coins in a menu should appear with an option at the bottom labelled "spend from". If you click it a window should open where you can spend coins from that specific address.

Alternatively if you just click the send tab and send coins from the window that opens your wallet will automatically choose which of your addresses containing coins to spend from. If you select the button labelled "max" your wallet will send all the coins in every address it contains (unless you have frozen some addresses).
2032  Bitcoin / Bitcoin Technical Support / Re: How to recover btc after windows reinstall on: June 27, 2017, 09:07:04 PM
Was the wallet encrypted (did it have a password)? If it wasn't encrypted then attempting salvaging the coins will be easier than if it was.

There is an alternative to using pywallet, but it requires more time and effort.

If it wasn't encrypted you could use a hex editor capable of searching a whole hard drive to search for this string of bytes 0201010420. The next the thirty-two bytes after that string could be a private key.

If you find one you can change it from raw hex to a normal format by pasting the thirty-two bytes into an offline copy of this webpage, which will also give you its associated address.

https://www.bitaddress.org/

This post explains how to use the webpage.

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

This hex editor is capable of searching a whole hard drive.

https://sourceforge.net/projects/wxhexeditor/

These screenshots explain how to open a disk, then search it for the hex string.

Click "devices", then "open disk device", then select the disk letter you want to search.



Click "edit", then "find".



This window should open. Paste the hex string into the the text box labelled "search", then click the button labelled "find all" and wait a very long time for it to search the whole drive.



If you try it run all software offline inside a virtual machine like virtualbox or vmware. Don't ever risk putting a private key on a computer that will ever be connected to the internet.

If you find any private keys you can install the electrum wallet and either import or sweep them into it using these instructions.

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

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

Electrum should sync almost immediately and give you fast access to your coins.

Don't ever boot from that hard drive again because doing so could wipe all traces of your coins.
Does that sequence always occur before every private key in your experience?. Thanks again.



Someone else did some testing and found that sequence before every key he tested. I also tested it and came to the same conclusion. However it might not always work.

Another sequence you can try searching for is 01036B65794104. If you find it and also find the sequence 0420 about 180 bytes later, then the next thirty-two bytes are probably a private key.

This quote explains it in more detail.


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.

i am having the private keys, the website worked. i used it offline and it is a really good idea but i can't find the button where to put them in blockchain.info , at me it doesn't show import when i go to settings/addresses

i will try to add them to an electrum wallet

I usually recommend importing or sweeping them into electrum. I can't remember why I suggested blockchain.info in that particular post. Later on in the same thread I recommended electrum.

If you sweep them into electrum you have to make a transaction and pay the relevant fees, but afterwards you only need to back up your wallet's seed words. If you import them you have to either back up the wallet file itself, or back up the private keys.

These are the import/sweep instructions from electrum's documentation.

Thanks, really appreciate this. Probably last chance saloon if my attempt with Recuva is anything to go by.
I do have the password, but don't know whether the wallet was locked the last time it was used. If this doesn't find anything then would pywallet be able to scan the whole drive?. Thanks again, and to anyone else that has given helpful comments. Smiley


Yes pywallet can scan a whole drive for a deleted wallet.dat. However, it's very old software and getting it working requires installing some very old versions of other software that can be difficult to find. I played around with it about half a year ago and had it working, but I can't remember all the steps I made. I'll have to test reinstalling it to work out some instructions.

Hopefully achow101's installation instructions from 2015 still work.

This is a screenshot of pywallet scanning a drive.

There's a user called spispi who just reported that after six days his ETH transaction was finally processed by poloniex. His situation was almost exactly the same as hwyzd's except he was using a different exchange. The withdrawal was marked as complete by the exchange, but wasn't confirmed by the network until days later. The network is overloaded.


Withdraw was marked as complete by Polo.
Txid not found on blockchain.

Its been 4 days now. Nobody answered my ticket.

Anyone else has the same issue?

I was able to do dash withdrawals with success though!

You think I might loose my ether?


Poloniex did process the withdraw today!
Plus it has answered all tickets!

It dipped down to $2000 a few weeks ago through panic selling, and a week later it was back up to $2800. The panic sellers from a few weeks ago must have regretted it, and today's panic sellers will probably regret it.

There's no particular rhyme or reason to any of it. I wouldn't want to be in the mind of someone heavily shorted or longed at present. I assume there's not much going on in there other than screeching.

Now is the perfect time to buy and HODL, then buy more if it goes any lower. Today's market is too unpredictable to go short or long.
Agreed, This might be our buy zone and then again so could 1500 although the trend line is very near. Good advice on cost averaging.

I can almost guarantee that a user called JimboToronto will log in later and  discuss his latest Bitcoin purchase from an ATM. He only buys the dips and hasn't sold a substantial amount yet. His strategy has worked extremely well for him.

until now iam not hear big exchanger and local exchange in italy, so i think is not effect about buying bitcoin and then can incraese bitcoin price


Strangely enough there's a new story in the press section explaining Italy's intentions to try regulating exchanges and introducing a registry for them. Italians will probably just buy from exchanges outside Italy if they bring the new rules in. Is it merely coincidence this story emerged at the same time as the bank bailouts?

New AML Law In Italy With New Rules On Bitcoin Exchangers

The AML4 (Directive 2015/859 UE) was introduced in Italy with its publication in the Italian Official Journal of the Legislative Decree 25th  May 2017, n. 90 (G.U. n. 140 of 19th June 2017) with the total reform of the legislative decree 231/2007.

The European Parliament has not yet approved the modification of AML4 with provisions regarding virtual currency (which will probably occur after discussion in plenary in late October 2017) but Italy anticipates some provisions, including Exchanger as an obliged entity for AML purposes.
The Italian Minister of Economy called for discussion over the draft of this proposed legislation in early December and obtained the opinion of Parliament.
The new rules concerning virtual currencies are included in several articles of the law as well as  the introduction of a specific registry for Virtual Currency Exchange.

You can easily get litecoin address/private key pair from jaxx wallet which is one of the trusted multicoin wallet out there.


Do you know about the Jaxx wallet ‘vulnerability’ that lead to at least $400,000 of customer's money getting stolen? I wouldn't recommend using it unless that ‘vulnerability’ gets fixed.


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.
