Topic: How to get Bitcoin Cash from many wallet/software/services with Coinomi (Read 21574 times)

I sent CLO from my Coinomi wallet to my ETH address on ClassicEtherWallet by mistake. The CLO are showing in ClassicEtherWallet but I can not access them for Cold Staking or to send back to the Coinomi wallet. Is there a way to import the CLO back to my Coinomi wallet since I have the private keys?

I think I may have lost all of my bitcoins trying to follow this guide unfortunately. I followed all the steps and everything was going correctly until everything completed. I sent 0.75 BTC from my Multibit classic wallet to the Coinomi app following the steps provided in the guide here. Once everything was completed it showed the same number in BCH, 0.75, that I had sent in BTC. None of my BTC was in the wallet after that on my PC or the app, only BCH could be found and showing just a value of 1k+, 0.75 BCH there. I am worried that It just converted my coins into BCH, 0.75 BTC to 0.75 BCH. The thought of losing over 7 thousand dollars for no reason is killing me inside. If anyone here could help me I would be so grateful.

UPDATE: It has been resolved. Make sure to move your coins out of the wallet before you do this or will lose money.

The thread where I figured out my problem.  https://bitcointalksearch.org/topic/help-lost-all-my-btc-trying-to-claim-bch-on-coinomi-2838191

Hi,
So I'm trying to claim my bitcoin cash using the method above, I got my list of 12 words and I past them in bip39-standalone.html
My question now is regarding the "Derived Addresses" I get in the result page of bip39-standalone.html
I get a list of 20 address [0-19] then I have a button "more rows" that shows another 20 and on and on and on it goes every time I hit the button.
In fact I dont know when it finished. I was unable to get to the end I always get more addresses.

My silly question is I must scan each and every address listed here to check if it has any bitcoin cash correct?
Every single address listed here was at one point created by my bitcoin wallet correct?

Is there any faster way to find out which of these addresses hold my bitcoin cash?
Thanks.

is it safe to keep using the same btc address in my BTC QT after the swap?

been using my address containing bch for years therefore is registered in many places

hi
i Accidentally sent bch to bcc
my seed are 18 words
i try bip39-master cant find private key
please help me

Are all the wallets in OP 100% safe?
I have been using bitcoin core, which should be 100% safe, but not easy to use.
Which wallet would you recommend?

This is the answer of greenadress support team


Hi,

As you may know, we recently announced some updates at https://blog.greenaddress.it/2017/09/06/segregated-witness-updates/ which includes backend support for signing bcash transactions. Please see the link for more details.

We provided this support in order to allow users to control their coins manually with respect to bcash. We are not however planning to support it in our wallets. We notified users of this as soon as possible after becoming aware of the bcash fork in order to allow users to move their coins if they wished to split themselves. Providing this support has already entailed considerable development and testing effort to ensure the safety and security of the services we provide. We are not able to provide technical support for splitting, transacting in or using bcash beyond the above.

Note that splitting coins is a technical process and the process may change depending on the development direction of bcash which like all contentious forks we neither support nor follow the development of. We have ensured as far as we are able that the service will not sign bcash transactions that can be replayed on the bitcoin main chain, this is the absolute limit of our support.

As you may be aware, a user at https://reddit.com/r/greenaddress has written a tool that allows splitting of bcash using a modified version of our garecovery tool which some people have reported success with. We have reviewed the code for bad intent and given the git commit hash of that reviewed version. If the tool is updated then we will similarly review the updated commits as and when we are able. We do not support the tool nor can make any guarantee on its quality. We will provide support in regards to the newly introduced api call https://api.greenaddress.it/vault.html#sign_alt_tx

Beyond this we offer no support whatsoever. It is each user's decision to use any third party tool and to ensure the security of their mnemonics etc while doing so. We are happy for users to discuss the tool and provide support for each other on the appropriate thread(s) on reddit subject to our normal moderation policy. This may change if the tool is changed to become malicious or the forum is spammed etc with bcash related topics or trolling.

Regards,
The GreenAddress support team

Guys, what about Greenaddress, anyone know how get bah from this wallet? I founded this instruction, but it is for Ubuntu users and I not really understand how to do it.

It worked flawlessly.
But, I'm worried about Electron permissions. It asked full network acces...
Should this wallet be a safe one?

1. The idea is to get your BTC out of the wallet whose seed you will be using to restore to another wallet prog., so if someone steals your seed (malicious- software/-BCHwallet/-seed extractor) they can not access your BTC. Other wallet prog. or paper wallet, doesn't matter.
3. Yes, that's the procedure. Every wallet that had BTC up till august 1-2017 12.00 utc should have the same amount of BCH in it. After the restore from seed to a BCH wallet, the BCH must show up.


@sir.humus, don't have an answer to that, try different wallets to retrieve you BCH perhaps?

@HostFat Thanks for this awesome guide. It really helps.
@Flat.E - thanks for your support in this thread, I've been reading it all.

I just need a few confirmations on what *I think* I must do in order to claim the BCH.
So, I have btc in a electrum android wallet. Some of them are still there, some were spent. I understand that only the ones BEFORE aug 1 split are eligible for BCH.

1. I think best solution is to move all bitcoins from the android electrum wallet to a paper wallet (yes, better to be safe than sorry with the private keys...)
2. I already got the android electrON apk file, checked the signature and checksum. I did not install it on my phone yet.
3. After electron Installation on android, I should restore the wallet from seed. And the BCH should be already there? I don't want to do something wrong.

Had somebody tried this, with success?
Thanks.

O.K.
So I did everything in the instructions for my android wallet,
and I found some addresses with cash inside.
BUT, the address most funded wasn't found...
In the address book on the app it's marked as an "Old address"

Anybody knows how can I restore this address?


UPDATE:
When I use gurnec's decrypt_bitcoinj_seed, it gives me my seed,
but a warning is popped which says:

I still have the wallet, so how can I back it up entirely?

Use electroncash on a windows pc.
In electroncash: file-new/restore, pick a name-next, standard wallet-next, "I already have a seed"-next, enter seed words- under option check bip39, next etc.

Anyone can help on it, please?

I tried to get private key for blockchain.info through the html code downloaded, but after I input 12 words, it listed a lot of addresses which none of them is my blockchain.info address. I did set the client to blockchain.info. Any idea on it?

Moving your Bitcoins from Multibit Classic to Electrum and claiming your Bitcoin Cash via Coinomi

First of all, there is the excellent work by the OP on page 1. I bought some Bitcoin in 2013 and I haven't been paying much attention to it since, because for me it was and is a long term investment. I had to do a lot of reading the past couple of days to catch up. The way I transferred my Bitcoins and claimed my Bitcoin Cash was a bit different. I decided to use Electrum as my new Bitcoin wallet and Coinomi as my Bitcoin Cash wallet.

• RTFM: Read the Electrum and Coinomi documentation and FAQ
• Install Electrum on your desktop and Coinomi on your Android smartphone
• Create a wallet on Electrum and a wallet on Coinomi (I chose for a Bitcoin and Bitcoin Cash wallet on Coinomi)
• Write down the seeds and the passwords
• Download and install Zint Barcode Studio (Windows only) unless you don't mind typing an entire private key in Coinomi to claim your Bitcoin Cash: https://sourceforge.net/projects/zint/
• Export the private keys from your Multibit Classic wallets one by one (do not password protect the files) (I will explain below this list why I did this)
• Import the private keys (one by one) in Electrum (New/Restore -> Standard -> Public Private key) (I tried it out with an empty Multibit Classic wallet first)
• Send the coins from the imported private key to the Electrum wallet you created in step 3 (you will have to pay a transaction fee). Wait for confirmation until proceeding to the next step.
• Claim your Bitcoin Cash. Open your Coinomi wallet, select Bitcoin Cash, click on the 3 vertical dots right upper corner and select sweep wallet. You can now enter the private key manually or use the qrcode generated by Zint. I will explain below this list how. Wait for confirmation. (I tried this out with empty wallets first, by manually typing the address and scanning the qrcode)
• Repeat the previous 3 steps for all your former Multibit Classic wallets
• Rejoice

The reason why I imported the private keys in Electrum instead of sending the coins from a Multibit Classic wallet to an Electrum wallet is that the maximum fee in Multibit Classic is 0.0005 BTC/kB. This is very low compared with current fees (0.0015 BTC/kB for confirmation within the hour) and you can wait a very long time before the transaction is confirmed. I didn't wanted to take the risk.

What is the private key? The private key file exported from Multibit Classic (no protected by a password) looks like this:

# KEEP YOUR PRIVATE KEYS SAFE !
# Anyone who can read this file can spend your bitcoin.
#
# Format:
#   [[]]
#
#   The Base58 encoded private keys are the same format as
#   produced by the Satoshi client/ sipa dumpprivkey utility.
#
#   Key createdAt is in UTC format as specified by ISO 8601
#   e.g: 2011-12-31T16:42:00Z . The century, 'T' and 'Z' are mandatory
#

2016-02-07T11:46:36Z
# End of private keys

If you enter the private key manually, you only need to type what is highlighted in red.
If you want Zint to create a qrcode so that you only have to scan it with Coinomi. Import from file in Zint. In the text editor (Zint) delete everything except the private key and click on 'OK'. Scan the qrcode with Coinomi.

1.Start ElectronCash (Make sure you have latest version) https://www.electroncash.org/
2.Click on New/Restore
3.Select wallet with two-factor authentication and click Next
4.Select I already have a seed and click "Next"
5.Enter your Electrum wallet seed and click Next
6.Select disable and click next
7.Enter password and click next etc.

But how would you get Bitcoin cash out of a multisig electrum address?

Had Multibit HD, but also an iPhone and Coinomi is not available for apple yet.
So I did this instead;

1) Installed Electrum, and created a brand new wallet
2) Transferred all bitcoin funds to this wallet from the Multibit HD wallet.
3) Installed Electron.
4) Created a wallet, using “I already have a seed”
5) Entered my 12-word Multibit HD seed, and checked “Bit-39 seed” under option
6) Used “m/0'” under derivation, instead of the default “m/44'/0'/0'”
7) A bit of sync… and the Bitcoin cash was available.

Worked like a charm…

For anyone seeing this.  It's due to the high number of transactions inputs within your wallet.  I followed the following the following video and was able to import the private keys into Electrum cash (make sure you are not doing this with standard electrum) from multibit classic.  Even then I was not able to move the whole amount at once due to the number of inputs.  I then sent the transactions in parts.  Since I was not sweeping all at once and was sending part of the funds in chunks I was able to move the funds successfully.
