Hi,
As per the title.
I have some BTC stored in an Electrum Wallet. I've read many guides on safe methods for claiming the BCH (equal in amount to BTC owned prior to hard fork). Most guides say to FIRST transfer the BTC from their original wallet in Electrum to a new Electrum wallet, then use the old (now with 0 balance) BTC address to claim BCH from.
I've just bought a Ledger Nano S, and set it up and created brand new BTC and BCH accounts on it. I haven't transferred anything to it yet.
What I'm wondering is can I simply transfer the BTC from my Electrum into my Ledger Nano S (instead of transferring to a new Electrum address) and then install Electron Cash (on a different machine, although, post-successful-transfer, I doubt it matters, but better be safe than sorry) and use the old Electrum BTC address to claim BCH from?
I hope what I'm asking is clear and also that I haven't inadvertently said something stupid.

Many thanks!
