online wallet goes offline - possible?

[cphxxx]

hey,

didnt find answer to it. I've got btc on my electrum wallet I always used and I wanted to retrieve finally bcc and btg so to make sure I wanted to create new electrum wallet to transfer my current balance. Still the fees are now so high that either I wait for at least last month fees or I figured maybe there's possibility of putting my current wallet to offline machine. If I copy my master key and change on (mostly) offline machine password for signing is it going to be safe?

Second question, just curiousity. When I created offline wallet how is that possible that wallet addresses are never going to repeat?

Cheers!

If I understand you correctly then STOP.  If you create your new BCH wallet using the private keys from the old BTC wallet you must make SURE the original BTC coins are moved first.  I understand the frustration of waiting for transactions to complete but if the BTC are not officially moved ANYONE with the private keys can take them.  Just so you know there could be a hundred computers running your wallet if you wanted to do it that way.  The BTC in the blockchain don't care about which computer supplies the private keys.  If the private keys are presented then the coins will obey and move.  We had lots of problems with folks installing "bad" Bitcoin cash software downloads.  I am not trying to scare you but with just a few posts you may not know how to protect yourself.  Unless you have reason to hasten this process you would be much safer doing the BCH thing after the original BTC have moved to a new address.  Any experienced user could easily move them now.  My suggestions are based upon your post count and to error on the side of caution for you.  Trying to help.

Note that simply moving the coins to a different address in the same wallet will not suffice since you intend to use the master private key or seed words to restore your wallet in bcc/bcg software. So you need to move them to a different electrum wallet entirely because all the address-specific private keys in a wallet are derived from the seed. This should also answer your second question about how the offline wallet has the same addresses as the online watch-only wallet. From the private key you derive the public key and hashing the public key gives you the address. All private keys in a deterministic wallet are derived from the seed.

hey, thanks guys.

no, I patiently waited, it took 5 days with 150satoshi to move small amount I wanted to test but it seems its on my new wallet. so when I see it on my watching only wallet it seems fine, right? looks like I can move my whole wallet.

So anyway, electron cash is safe to use to retrieve bch? and when I will later try to retrieve btg I should move my bch to another wallet? one more thing was on my mind but cant remember what..

thank you for your advices.

Yes, ElectronCash is safe... as long as you get the official download from the official site... just like Electrum, there are a lot of fake/scam wallets and sites trying to steal your seed/private keys etc...

Go here: https://electroncash.org/#download

And remember to check the signatures/hashes etc.
