To securely get your BCash, I recommend you to follow this:
1. Create a new BTC Wallet, let's name it {B}.
.........
That sounds like a good idea, why did I not think of that myself.
I still don't think the seed will show imported keys in Electron cash (why else would it have given me that warning) but at least I could try. Thanks!
But it would be a bit of a logistical nightmare. Could I not simply enter the keys into Electron Cash just like I did in Electrum, or is that not possible? I have both my public and private keys.
Yes, you will only need a private key on which you had your bitcoin balance at the moment of the fork, and simply import that into Electron Cash, it should work.
Note that you will only see the bitcoin cash balance of said adress that belongs to the private key ( unless it is a MPK), and that you'll need to import change adresses etcetera manually aswell.
Why would it not work? Have you tried it yet? Private keys are ALL derivated in the same way, so it wouldn't matter if it is created in a wallet X 10 years ago, or in wallet Y 10 minutes ago.
Do make sure you're using the right electron cash, and that you're not running a scam wallet, (check the signatures of your download etc.) Otherwise all of your bitcoin cash AND bitcoin might be lost.
Thanks AdolfinWolf. No, I have not tried it yet. I made some stupid mistakes in the past and almost lost my bitcoin. That is why I want to make sure I don't make a similar mistake again.
The keys were generated with Multibit long ago. When I recently entered the keys into Electrum it gave me the message: Warning, imported keys can not be recovered using the seed! That gave me the idea that the keys must be generated by, and somehow connected to, Multibit. And when I would enter the seed into Electron Cash, it would not see the imported keys. Does my reasoning make sense?
I could simply try it, if you think nothing bad will happen. I hope you understand why I am being very careful here, I got my bitcoin back and don' t want to jeopardise that again.
Is Electron Cash dedicated to Bitcoin Cash only? Can it in no way interfere with my bitcoin BTC?
If the seed was generated in MultiBit, then you need to import your BTC wallet using the seed in MultiBit. There you would get a list of all your addresses. You may then copy the Private keys of all the addresses with balances and use Electron Cash to import in a new wallet to claim your BCH.
If the developers of electron cash have malicious intent then they may get your btc from your private keys because it is NOT the official wallet by Electrum !
So I recommend you to transfer your btc to a new address, just to be on a safer side.
That won't work because the seed derivation method used by Multibit is different then the one Electrum uses. ( Correct me if i'm wrong)
So yes, your reasong does kind of make sense. You will either need to use something like this,
https://bitcoin.stackexchange.com/questions/53419/how-do-i-import-a-multibit-hd-wallet-with-seeds-into-electrum, which is a lot of hassle without alot of reasoning, in my opinion.
or simply just import the private keys..
