I've been hanging on to my bitcoin cash as a hedge against Segwit. I'm not knowledgeable enough about the programming side of things to know whether the concerns are legit, so I use the better-safe-than-sorry approach and buy insurance. I've lost a bit of money on my bitcoin cash since I bought it, but I'm still in the black by 100% on that amount vs. my original stake a year ago when I got into cryptos, so I'm not too broke up about it. I'm still not entirely convinced that Segwit is the way to go just based on my layman's interpretation of it.
