If miners decide they want big blocks and shift the majority of their hashrate then BCC does become Bitcoin and your Segwit tokens would end up probably being worthless sooner than later. Best to hold BCC to stay safe and protect your assets.
Actually, I agree. I think it's
extremely unlikely that BCC will become Bitcoin's main chain, but people underestimate the support that it could have in the future.
There's thousands of people over on r/btc and some other places supporting larger blocks. There's also the fact that many groups such as BITMAIN actually support BCC but are currently leaving it alone to support SegWitx2. BCC will certainly not go right to zero anyway, and it will always have a niche for those who prefer onchain scaling.
If you don't support BCC's cause, all you need to do is ignore the BCC that you have a right to and continue spending your BTC. If you ever feel that it has a high enough value in the future or you need to use it, you can do so later.
