No one here can help you. Bittrex are having a lot of troubles lately... They have blocked hundreds (if not thousands) of accounts recently due to being forced to stop serving customers from specific countries due to legal requirements.

As such, their support workload has increased massively with everyone creating support tickets. Wait times have been as long as 2 months looking at some posts. Read the Bittrex threads here: https://bitcointalk.org/index.php?board=83.0

Unfortunately, all you can do is log your ticket and wait.

It possibly makes a big difference...

The important question is.. do you have access to the private keys for the BCH wallet? If you DON'T have the private key for the BCH address, you're pretty much screwed.

You will only be able to recover the BTC, by importing the BCH private key (for the BCH address you sent the BTC to), into a BTC wallet.

If it was an online service (like an exchange or webwallets)... Chances are you won't be able to get the private key... and your only hope will be if the one service can help. You'll need to contact the support for the service you are using and ask them for assistance.

If you do have access to the private keys, then as stated, import the private key into a BTC wallet... And the BTC should show up.

Step 1. Click Here: https://github.com/downloads/jackjack-jj/pywallet/PWI_0.0.3.exe

Step 2. Run the downloaded .exe file

Step 3. Extract the files. It is a "WinRAR autoextractor"... essentially a fancy "ZIP" file... that doesn't require you to have WinRAR or 7Zip or anything installed. Unfortunately, it also appears to be in French... basically, choose a directory where you want to extract the files to using the "Dossier de destination" (aka "Destination Folder") textbox... you can click the button to "Parcourir" (aka "Browse") to select the one you want using windows explorer. Then click the "Installer" button (aka "Install")... NOTE: "Annuler" = "Cancel".

Step 4. Run through the installation process, it will install some necessary utils and python stuff... so as the instructions say, click all the "Yes/Next/I Agree/Ok" buttons to install everything.

Step 5. Goto to the directory, that you selected in Step 3.

Step 6. run "pywallet.bat" (you can simply double click on it)... it'll open up a window and you'll see it "start up a server"... after you see the line: "Starting factory <twisted.web.server.Site instance..." move to the next step.

Step 7. Open the URL: http://localhost:8989/ in your webbrowser



What you are attempting to do (recover your wallet.dat using pywallet), is not really a "beginner" level exercise. The learning curve is going to be pretty steep. It is a bit like someone who has "limited jet engine knowledge"... attempting to disassemble and repair a jet engine.

How are you determining that Bitcoin Core took "10 GB of your SSD drive"?

Did you just check the free space and notice that it had dropped? What operating system are you using?

The thing is, the only person in control of the "dangerous behaviour" is YOU.

Portable versions are only dangerous if you engage in risky activity and don't take adequate precautions... it's a bit like sex... if you sleep with random people and don't use condoms/birth control, there can be serious consequences (STDs/STIs... unwanted pregnancy etc)

Likewise with using a portable bitcoin wallet, you put your USB key into random computers without properly assessing the risks and making sure those computers are not infected with viruses/malware/keyloggers, there can be serious consequnces (loss of coins)

For the benefit of anyone else reading this thread, as I mentioned in PM... it appears that at some point (I suspect since v3.0.0) the options have changed ever so slightly in Electrum when importing/restore wallets...

Standard wallets are now ONLY for HD seeds or "Master" public/private keys (ie. xpubs/ypubs/zpubs or xprvs/yprvs/zprvs etc). As per the "Standard wallet -> Use public or private keys" option:




So now, you CANNOT import a single WIF format private key (ie. a "5", "L" or "K" Base58 encoded private key) if you select "Standard" wallet.

If your private key looks like:
5HsyUcGbVmbjpCfcjnSFV1D3GuxtfL5Jmk3ETa9L2zX4jKWe1Kj
L5GjoaFZmZAotojw7noR3qRF78FDEQsrPSLhbxZgvapxppQ5UUrG
KwVzGrfqFyrKyLVSjqYSvbv93Emh2BC1SUxrQHHm1nshTiNQ2Sre

When asked "What type of wallet you want to create?"... DO NOT select "Standard wallet"... you MUST select the LAST option ("Import bitcoin addresses or private keys"):



If you read the next dialog window properly... It'll say "Enter a list of Bitcoin address (this will create a watching-only wallet), OR a list of private keys.":


This does NOT mean a list of private keys will make a watching wallet... it means you enter either a list of addresses, which will create the watching-only wallet... OR you can enter a list of private keys (which will create a normal spending wallet, even though it is not explicitly stated... I've tested it )

Pywallet has a thread here with download and install instructions: https://bitcointalk.org/index.php?topic=34028.0

Probably has not a lot to do with your choice of bitcoin/bitcoin cash wallet... and a lot to do with keyloggers/malware etc...

Whatever the cause, it is a good example of why people suggest moving BTC off of any private keys BEFORE attempting to claim the BCH or other fork coins from them... exposing your private key to an online environment puts coins at risk.

Do you have an "orange" Nano S? Is the casing orange in colour?



If so, that is your issue... Apparently these are special editions and can't be updated:

https://ledger.groovehq.com/knowledge_base/topics/unable-to-install-os-updater

Are you trying to update the actual device firmware or update the Bitcoin "app" using Ledger Manager?

With the "Ledger Manager" Chrome app... plug in the Ledger, enter your PIN etc... click "applications". The manager app will give the list of all the available apps:


Delete the "Bitcoin" app by clicking the grey trashcan icon... Then reinstall the Bitcoin app, by clicking the green "download arrow" icon.

It should say version 1.1.9 or higher... If not, you might need to update the chrome app

Is that paper backup actually generating the same addresses that have your balance? Or is it generating completely different addresses?

Also, have you checked those addresses on a block explorer?

If seed 100% works in MBHD, it could Possibly be a "gap limit" issue? MBHD has default of 50-100 i think, Electrum has 20. Plus, I vaguely remember that MultiBit HD would "generate" a new receive address every time you click on the receive tab, regardless of whether or not the  previous address had actually been used. So it could simply be a case of your coins being in addresses out past  Electrum's default gap limit of 20.

Restore the seed into Electrum, BIP39, dpath of m/0'

Then: "View -> show console", click the "console" tab and enter the following two commands:
see if your coins show up... if they do, great, do the same thing in ElectronCash.

If they dont , try same commands with 200



you mean the seed had an extra password attached? if so, try using the "extend seed with extra word" option during seed entry... and enter your password there.

The numbers are specific to MBHD, they basically represent the wallet creation date and are used by MBHD to speed up transaction scanning after a restore... basically it wont look for transactions BEFORE the wallet was first created.

Welcome to August/September 2017...

Firstly, relax... your Ledger Nano S HAS NOT been "hacked"!

It was a "minor" UI issue with the Ledger due to the wallet being updated for SegWit etc... All it is asking you to do is confirm Output #2 for the transaction which is a "change" address in your wallet! Have a read here:
https://www.reddit.com/r/ledgerwallet/comments/6zgy1x/nano_s_asks_to_confirm_change_output_when_sending/
https://www.reddit.com/r/ledgerwallet/comments/6yn99h/ledger_nano_s_output2/
https://www.reddit.com/r/ledgerwallet/comments/6wws8e/comfirm_output_2/

For reference, "btchip" on reddit is the "Ledger CTO"... they know what they're talking about.

This issue should have been resolved if you update the "Bitcoin" app to at least version 1.1.9 on the Nano S using the Ledger Wallet Manager (https://www.ledgerwallet.com/apps/manager)

Theoretically... it should be possible to create a transaction to recover your BCH that has been sent to a SegWit address... refer: https://www.reddit.com/r/btc/comments/6z56x3/attention_benevolent_bch_miners_a_bch/

There are a number of problems associated with this, one of the big ones, as the OP of that thread explains ("More Problems" section), is that by creating and broadcasting that transaction, it would be possible for someone to then take the "hash" from the broadcast transaction and create their own transaction using that hash which sends the coins where they want it to go in "double spend"...

I have no idea what the likelihood of that happening is... but given there is a chance it could happen, I'd also wager that people are scanning the people for these types of transactions

As far as I'm aware, at this point in time... it isn't possible to get those BCH from a SegWit address... but it MIGHT be possible at some point in the future.

You can't just open the file and expect to see what you're looking for... it is an encrypted backup file... that's the whole point!

Now that you have a copy of the backup file on your PC, you go and do this if you want your seed and/or private keys: https://bitcointalk.org/index.php?topic=2362195.msg24205943#msg24205943

Just adding... that if you do this (ie. enter your Trezor seed into your computer)... you should consider that Trezor seed compromised... and take appropriate action to generate a new seed for your Trezor and move all your coins to it as soon as possible.

You will have dramatically reduced the "security" of all the wallets/addresses/coins that are using your current seed if you enter that seed into any other wallet software. It is supposed to be written on a piece of paper and stored safely OFFLINE for a reason!

No sure why Electron Cash keeps crashing... you'd need to talk to the ElectronCash Devs (I'd suggest logging an issue on their GitHub issue tracker here: https://github.com/fyookball/electrum/issues)

It'll likely be related to this issue here: https://github.com/fyookball/electrum/issues/236


Also, the reason it won't work when using the "private keys"... is that a 2FA wallet is generated from a combination of multiple (ie. three) private keys... and when you use the "export" feature in Electrum, it'll only show you one of those three keys for any given address... when you import that one private key into another wallet, it cannot possibly generate the same addresses, as you're missing two of the private keys.

That's not exactly true in ALL fork situations... it works with BCH because they implemented full 2-way replay protection... but imagine if S2X had gone ahead with no replay protection... you try this and send your coins to yourself thinking, great, now I'm safe... and then send those "split" coins to someone else... Thief then just rebroadcasts the whole chain of transactions (ie. BOTH transactions you've made) and boom, your coins are now gone.

It isn't just a simple case of "send to yourself", it is a LOT more complicated than that... you need to start generating transactions that use inputs which don't exist on the other chain to make it impossible for that transaction to be valid on the other chain. The "easiest" way to achieve that is to get hold of coins that come from a "coinbase" transaction (ie. the block reward, NOT the exchange with the same name)

Splitting coins when there is no replay protection is NOT for the uninformed or technically challenged... it is complicated and exposes you to potential loss of coins on both sides of the fork.

In the case of BCH (and other forks with replay protection)... moving your BTC is not "splitting" them... they're automatically split because of the replay protection. What you're doing is just putting them onto different private keys, so that if the fork wallet you use is "evil" and steals your seed/keys... only your fork coins are at risk.


Isn't that the whole point of the Airgapped PC... it doesn't just stop things getting IN... it stops things getting OUT as well?

Do you "keys" look like long strings of random characters that start with a "5", an "L" or a "K"... like this:

5HsyUcGbVmbjpCfcjnSFV1D3GuxtfL5Jmk3ETa9L2zX4jKWe1Kj
L5GjoaFZmZAotojw7noR3qRF78FDEQsrPSLhbxZgvapxppQ5UUrG
KwVzGrfqFyrKyLVSjqYSvbv93Emh2BC1SUxrQHHm1nshTiNQ2Sre

or do they look like something else?

WARNING: DO NOT post your private keys here!!

If they do NOT start with a "5", an "L" or a "K"... then you are exporting them incorrectly. You should NOT be exporting with a password, otherwise the file will likely be encrypted and you'll just see text like this:



The output file should look like this:



If that isn't how your output file looks, maybe you should make a copy of your .wallet file... and then open it using the last version of MultiBit Classic v0.5.19 - https://multibit.org/release-info/classic/v0.5.19.html

Then try exporting your "keys" using v0.5.19... remember, DO NOT password protect the export file.

Also, when copying the keys from that file to paste into Electrum, DO NOT copy the date and time at the end!

As far as I'm aware... there are no "accelerator" services available for BCH... I though that was the whole point behind 8meg blocks!

transactions shouldn't get stuck because the blocks aren't like to be full, so miners will just include ALL available transactions.
