To my knowledge, only one of btc or b2x will survive. Right now it seems to be btc which will survive. Rumors of corporate banking takeover behind the segwit coin etc.

Bitcoin(s) combined value of all forks and original chain is now over 10000usd.

If b2x drops from 1700usd futures trading prices to zero btc will gain that same amount and we'll see 8500-9000usd btc after the forkening.

Sure..bitcoin could retract but remember the long term incentives to hodl.

Some profit taking within the cryptospace could occur, but fiat will continually be converted into cryptocurrencies. Were riding a huge wave now. Surf it or get washed up on shore
