I think OP has said everything with immense wisdom, I from the beginning that came out BCH said it was a dane the worst things that were going to come, in fact it is like that, when the edge of madness passed through when applying a FORK to BCH, I said to myself, wow how far can it go? The only currency that Forks can make is to bitcoin, to try to want to knock down its value in any way, but Bitcoin is so strong that it has strengthened after these Forks, it is natural, until now no altcoin could be superior, simply because no It has a life of its own, they all depend on Bitcoin.
Bitcoin is the leading currency, until many times want to knock down its value, but the technology behind it is so strong, that Blockchain easily should be listed as one of the wonders of the world, there is no technology that brings so much progress, or any currency that can reach Bitcoin.
