I don't see that as true for Bitcoin Cash for a number of reasons that I've discussed numerous times, but will likely make a video on separately in the future. I understand preferring it, but think it will ultimately cost you every penny you have in it so do at your own risk. For Ethereum Classic, I think the argument is much stronger for it being the "real" Ethereum given immutability is often cited as an all-powerful feature of utilizing blockchain technology, so the current Ethereum made a very real sacrifice. However, I have concerns over its longer-term adoption so I wouldn't personally invest in it.
