I don't think so. They have been claiming that they are the true bitcoin because their coin is the one described by Satoshi but for me Bitcoin Cash is an altcoin not THE bitcoin. I may buy BCH for short term profit to have more bitcoin. It is just a hype now and many are switching to Bitcoin Cash. If you are getting in now then better watch the price carefully because it has been increasing for some time already so it is bound for a correction and may continue to go down and be dumped by the people causing this hype. Cryptocurrency market is full of manipulation and this is one of it.
