True but who cares! BCH price is crazy and people love to get some free money in short time, even it's too much risk deal this shit coin.
I'm trader and sold my BCH, but i donćt see anything else interesting in it. This kind of rivalry can harm BTC, or can create even bigger damage to foolish investors who believe that parity 1:1 can happen. How many forks we will have in the future? Do wee need so many coins? No!
If Bitcoin Cash can be long term harmful to Bitcoin than it should. This is what capitalism is, the natural selection, it will always work and be at work no matter what we do. If BCH just fails and everybody just loses their money, then at least those people and people looking at them will learn and some would have already know that would happen. If it doesn't fail then everybody who thought it would will have something to learn as well. Everything will fall in it's place as time goes by. it might take few weeks, it might take years, it might take centuries, nobody can know how long, but eventually it will. It might cost a lot, but sometimes mistakes cost us more then we gain from the knowledge we get out of it, but at least they are new mistakes and at least eventually people will stop making the same one again and again. It makes no sense to assume otherwise.
Everything will be fine, it always turns out just fine. Freedom of choice is never a bad thing in the long run.
