A super majority of people will not do that before interacting with BCH. Do you really expect the average user to know the best way to proceed? Most of them know nothing besides the part "import your private key into a BCH wallet to use and dump it".
What if they lose their BTC itself if it's a stealing operation here?
What if they are unable to even load their ^BCH^ anywhere for a possible dump?
For it to get dumped it needs buyers as well, where the hell are those buyers coming from?
I am too much confused about this situation and can't hold on to see what will be the major outcome and which one wins to be the one and only bitcoin, the original De Facto one as OP said. Not knowing too much but just like everyone else here, I would never want Bitcoin to split and even if it does I want Bitcoin to remain superior with major support of mining powers.
