I am back again with another query

i am trying to claim my BCH from this old wallet but every time i try and sweep the private keys i have it says 'no input found'

i have tried using the 2 private keys i successfully swept for BTC in my new electrum wallet but got the same result

are they not the correct keys? do i need to find some others?

thanks

in this transaction https://blockchain.info/tx/9732bc17cd2d3468a1af8e3c3f83a67e87e45b865f10dcc8e15904e1c80da955
you're sending to 1FsdYR2AMw... and 1PXpkd9fd... and I believe your address is 1PXpkd9fd...
try importing the key for 1PXpkd9fd... it should have balance in that address on BCH chain

If you successfully swept BTC from them, then the private-keys are valid (the same private-key is valid for BTC and BCH).

My guess is that there is no BCH in the wallet, so there is no inputs to spend. Did you make sure the address isn't empty by searching them in a BCH explorer[1]?

If the addresses aren't empty, import them in a Electron Cash wallet and see if there is any balance. Then, try to spend them normally.

is it safe to install the ~~electrum~~ cash wallet on the same machine? i have read you should empty your electrum wallet and do it on another machine. maybe thats over cautious?

The safe approach is not trusting it, and taking precautions. You're talking about large amounts of money, so being very careful doesn't hurt.
I don't trust Electron Cash on my system (note the correct spelling, many phishing sites try to give you compromised wallets!), so I use it in a VM just to be sure. It worked fine without problems though.
The real site: Electron Cash.

OMG i think i have done it!!

thanks mocacinno this worked:

If you don't want to do this, you should export the private key belonging to the change address of the last transaction that was confirmed...

I looked at the transaction, found the 'change address', dumped the private key for that and then went to electrum and did a sweep and its now showing as an unconfirmed transaction

the other address i swept earlier how now confirmed so hopefully this one will do the same

can i buy you a beer seeing as its friday night?

I'm glad it worked, a tip isn't really necessary. That being said: i'm certainly happy when i receive a small tip.
My tipping address is in my profile, it's the same address for bitcoin and bitcoin cash (since you found the private key for your bitcoin address, and you swept the unspent outputs, you can safely import the private key in the electrum wallet for bitcoin cash and spend those BCH to Wink

... Well, wait untill the sweeping transaction is confirmed just to be sure.

cool, i will send a little bitcoin cash to the address in your profile then

is it safe to install the electrum cash wallet on the same machine? i have read you should empty your electrum wallet and do it on another machine. maybe thats over cautious?

Personally, i have many machines running, i chose to use a different machine for electron cash just to be sure, so i can't really comment on this (sorry)

back for some more questions i am afraid

i have located the file on my PC

C:\Users\james\AppData\Roaming\Bitcoin

i have installed bitcoin core and it is running on my mac but no bitcoin folder has been created here:

~/Library/Application Support/Bitcoin

I have tried the same thing on another PC in the house and the same issue exists - no bitcoin folder in which to find and swap the wallet.dat file

i dont have to wait for it to sync for it to create this folder do i?

cheers

The data directory seems to be correct

https://en.bitcoin.it/wiki/Data_directory

You can always manually create it if it doesn't exist, or you can start bitcoin-qt with the command line paramater -datadir=

sorry, what i am saying is that no Bitcoin directory has been created at all on my MAC

it should be here - ~/Library/Application Support/Bitcoin but there is no /bitcoin folder

Like i said: you can always manually create one and put the copy of your wallet.dat in it, or you can put the wallet.dat in any other folder on your machine, and use the -datadir startup parameter.

sorry, i see what you have said now, its all way above my level of understanding so i am struggling to understand much!

i will have a look at that

You do have to run the wallet for the data directory to be created, if you haven't ran it before.

I would really recommend you to just prune the Blockchain on your PC instead of moving it around, a lot less hassle. Can you create a file (not text file) and name it bitcoin.conf. Put the following inside of it:

Code:

prune=550

The next time you start Bitcoin Core, the blocks will be pruned and the total size of the block files will not exceed 550mb.

as you can see from the transaction history nothing much has come or gone since 2013

This address had transactions 2 days ago (in and out!). How did that happen if your wallet isn't synchronized? Did you import this address' private key into Electrum already?

i dont know how that has happened, i sent them as tests over a week ago and they dropped into my coinbase account 2 days ago, i did not import the private keys

i am completely baffled!

sorry, i missed the last part of your last reply

i will try and do that on another computer with more space

thanks so much, i will let you know if works!

The idear of using a second computer is just to minimize the odds of a messup... The second computer doesn't have to have more space, you don't need to wait untill core is fully synce'd to dump the wallet, or a more recent version of bitcoin core can also be run in pruned mode so you'd only need about ~10Gb of diskspace.

Just make sure you use a COPY of your wallet.dat, and make sure you keep an original copy of the wallet.dat in a safe place. Things might go wrong, but as long as you have an untouched copy of your wallet.dat, all problems should be fixable.

EDIT:
rather important sidenode: AFTER you've moved your funds to a clean wallet, hold on to those private keys, they can be used to import into a bitcoin cash wallet, a bitcoin gold wallet, dig for clams,... An address funded with +1BTC before the blockheigts on which these altcoins forked is holding hundreds of USD (in fiat value) worth of altcoins on alternative blockchains!

thanks, i will make sure to do that

i bet i will struggle with it all though! thanks again
