Any chance you can advise how you resolved it? It might help other users in the future...
I assume it was simply because of the change in Electrum setup where you need select the wallet type as "import Bitcoin addresses or private keys" and you know need to include the "script type"... For example:
p2pkh:privkeyhere
as opposed to just copy/pasting privkeys like you used to be able to

That's a fairly easy task...
Your basic steps are fine... and it is good to see that you've done some research, enough to know that MBC's fees can be problematic!
You could do the following if you want to safeguard your BTC, before accessing the BCH:
1) Backup your private keys from MBC
2) IMPORT the private keys into an Electrum wallet (File -> New\Restore -> Import Bitcoin Address or Private keys - NOTE this is different from the youtube videos released by MultiBit devs!)
3) SEND the coins from your IMPORTED Electrum wallet to a different BTC wallet (I'd suggest a "standard" Electrum wallet)
4) IMPORT the keys from MBC into Electron Cash (https://electroncash.org/#download)
You would then have BTC in one wallet... and BCH in another.
NOTE: At the current moment in time, fees are SUPER low, so it should be fine if you want to use MBC to send your BTC... I sent a transaction this morning with 1 sat/byte fees and it got next block confirmation!

Sorry to drag this up again.
Firstly, thanks for the info above. Really useful.
I finally got around to grabbing my btc cash from an old multibit wallet address. I completed steps 1 to 3 fine.
I then got to step 4 above. But when I try to import my private key into the electron wallet from MBC, the next button is greyed out. This a common issue? I'm guessing it has something to do with the way it stores the private keys?
Thanks in advance

Excellent, sent you a PM with the details... Also, you might want to look at getting your "BitcoinGold" as well...
Unfortunately, there isn't an "Electrum"-like wallet for BTG, so, the options are the full BitcoinGold Core wallet (with full blockchain download) or sweeping keys using Coinomi etc.

Brother, that worked like magic.
I now have an Electron Cash wallet with a verified balance and an Electrum wallet with a verified balance.
Thanks a lot, sir. Where's the tip jar?

Hello folks,
I'm in the same basic boat –coins in old multibit wallet- and I think i understand but I'm a bit literal minded so I am going to list the instructions as i understand them and if you guys would either confirm or correct, I would appreciate it.
1) Backup the Private Key from my Multibit Classic wallet
2) Move the BTC to some other wallet so the Private key I have backed up is associated with the now empty Multibit wallet
3) Import the Private key into a BCH wallet (Electrum, etc) and the Bitcoin cash will appear.
-- Now I have two wallets, one with BTC and one with BCH, correct?
As I understand it, it can be tough to transfer out of the old Multibit because the fee cannot be set high enough. So I would perform Step 2...how, exactly? I'm afraid I don't understand enough to even ask an intelligent question.
Many thanks,
Drew

Yes, you can... Just copy ONLY the base58 part BEFORE the date/timestamp...
For instance, in this example:
If you have multiple keys, enter them all in, one per line
For instance, in this example:
Quote
# 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
#
5Jp793Ev1ynKyRCAh2M5XfUAasFDLiPF1uYTuvA8ENRjdeyoKq8 2017-10-03T19:22:13Z
Only copy/paste the bit in bold! That is the private key.# Anyone who can read this file can spend your bitcoin.

Hey, I also have the problem trying to import a private key from MultiBit into Electron Cash. The next button is always greyed out even though my key is not password protected.
When I exported the multibit classic key it gave me a .key file. Is that what I need?
Any help for a noob is much appreciated. Thanks!
edit: The key appears to be in this format according to the comments in the file:[[]]
Apparently you can't use this kind of compressed key to import into modern wallets. Any ideas on how to export in a format or decompress the compressed key?

I have some bitcoin in a classic wallet from before the fork, so would like to see if I can get some bitcoin cash as well?
Ive tried electrum and electron cash, and when I paste the key on either it doesnt highlight the "next" button for me to proceed.
Its a quite old version of multibit, version 0.5.1.8 IIRC
Is there any sort of dummies guide to this to show what I might be doing wrong?

Doh!
Just realised I was trying to import a file which was password encrpyted, LOL!

the strange thing is, there should have been a password for that wallet and now it launched and showed how many coins there are on the wallet without asking for the password. or will it ask for the password if I try to export private keys?
Hi. Yes this is correct. Cool that everything works for you Multibit classic is not asking for any passwords at start-up.
Your passcode will come in handy while doing some operations with the wallet, sending BTC or signing personal massage etc.
Safety reasons dictate to import "empty" private keys in to BCH wallet.
So make sure you have bitcoins stored in a different wallet while working on retrieving BCH.

Hi,
this old laptop that the multibit classic is on I never use. I have a diffeent one that I use daily.
I typed to the terminalto the laptop that has the multibit classic
sudo apt-get install openjdk-7-jre
turned out I have the openjdk already installed
the solution seems to be for running of multibit classic: right click on it and set it to executable, now it runs.
the strange thing is, there should have been a password for that wallet and now it launched and showed how many coins there are on the wallet without asking for the password. or will it ask for the password if I try to export private keys?
I don't want to send my private keys to any BCH wallet for fear that they can then steal the BTC that I gave them my private keys for, am I thinking this right?

Hi,
could you help me please with the following issue?
An acquaintance made for me a Multibit Classic wallet back in March 2014 on Ubuntu 12.04 LTS. I have i on a laptop/netbook that has not been online since 2014.
We encrypted the wallet (I still have the password).
I would like to transfer the BTC to a different wallet(Iguess by exporing my private keys from the wallet), to claim by BCC/BCH and in the end store it on my Trezor.
What do I have to click in Ubuntu to start the wallet at all?
I do not
see any icon to click on.
I have copies of the multibit.tar.gz file saved on a pendrive and multiple email adresses.
thank you very much for your help

When you have it up and running, the exe.jre file will become executable, you can create a shortcut to it, etc.
How to Java on 12.04 -> Link
How to shortcut on 12.04 -> Link
Recommended way is to install python3 and use electrum any way, as this old multibit will only make you troubles, it is just to old and sending bitcoins from it is close to impossible due to outdated fee slider. You wont be able to set proper fee and you transaction will get stuck.

HCP
Thanks for that.
Anyway it is a very fortunate thing you are migrating from multibit classic.Thanks for that.
Are you aware that this wallet is horribly outdated? Look on you multibit fee slider
you cant even set it 50% amount of fee required for painless transaction! I would advise not to send bitcoins from it at all.Import private keys to something else, electrum is a good choice and than empty that wallet in order to prepare it for the post fork actions. Otherwise you can face some consequences, from ultra long confirmation time to coins loss (worst case scenario, highly unlikely). I was a classic user for long time and believe me, electrum is way better.
Note: dont use ElectronCash on the same machine as electrum! They may share the same settings folders (but Im not 100% sure).

Thanks for that.

Yes... If you import these keys into a BCH wallet, you will have access to the amount of BCH equal to the amount of BTC that was stored on those keys when the fork happened
August 20, 2017, 07:38:21 AM
So As long as I have the private keys of the Multibit Classic wallet of the btc Before the hard fork, these Keys should be able to extract the bitcoin cash ?
Thanks Again
Thanks Again
August 19, 2017, 06:24:31 PM
As long as you had BTC on those private keys when the fork happened, they will have BCH on them now (assuming you haven't moved the BCH). It makes no difference what you've done with the BTC since the fork occurred as the chains are separate. BTC transactions do not affect BCH... and BCH transactions do not affect BTC.
August 19, 2017, 09:37:02 AM
Ok
A vitally important Question here. If I transfer my BTC from Multibit Classic to a new wallet say electrum. Can I then import the private key from the now empty multibit classic wallet into electron wallet and my Bitcoin Cash will still be able to be extracted? Will the electron cash wallet not know that my multibit classic wallet was emptied ?

Firstly, No need to start multiple threads 8 hours apart asking the same question. 
Secondly, no... you can't extract Bitcoin Cash from MultiBit Classic... what you can do is export your private keys from MultiBit Classic and import them into a Bitcoin Cash compatible wallet. You can find BCH wallets listed here: https://www.bitcoincash.org/
If you want it fast and easy, I'd recommend ElectronCash... import (or sweep) your private keys and your BCH should show up...
Obviously, exporting keys should not be taken lightly... it does pose a security risk to your BTC stored on those keys. Better if you move the BTC to new wallet (NOTE: MBClassic is very old and is no longer supported) with new keys etc... and then claim your BCH.

Hi Folks
I have Bitcoin in a Multibit Classic Wallet stored off line before and after the fork
Is it possible to extract Bitcoin Cash from Multi Bit Classic ?
