Some people would barely care about what's appropriate and what isn't if they are looking for profits, they would even mine a coin that might be associated with a platform that has scammed millions of people as long as they know they are going to get profit out of it. However, in OP's case, I believe he might have thought that since BCH isn't Bitcoin or as popular as it is, he might be able to mine it without having to buy ASICs which isn't true.

I'm not sure about the level of mining difficulty for BCH as I have never done any research on it, but if someone is going to buy mining hardware, they should rather try mining something that might be more profitable for them and wouldn't make them spend all the money earned on electricity being consumed.
