What I did was that I moved my BTC to a new Electrum wallet AFTER the fork and then used the seed from the old (and now empty) wallet in Electron Cash. My BCH is now there and all looks good so far. I wrote a post about it but I don't want to self-promote it in your discussion.
I'm considering between holding and selling 50%. Not decided yet. Since it's a free money and I don't have that much of it, there isn't much to lose and I'll probably hold.
I think the way you describe is a secure way, at least you can never loose your BTC. For me it is no problem if you link to your post in the comments as long as it is relevant content. I will keep my new altcoin for the long term, however I don't see anything valuable in it, it can always function as a hedge on failure of BTC or can get pumped by certain rich entities.
Thank you! Yes, the priority was to make sure that I can't lose my BTC. Even though I don't plan to do anything with BCH, I like the idea of having an opportunity to do so if I decide. I'm really curious to see how is it going to look in a few years.
