I think bitcoin will continue to soar as long as more people are getting interested and investing in it. In comparison btw bitcoin and bitcoincash, however, bitcoin is the oldest cypto and I perceive btc to have stood the test of term over those hard time struggling to survive. Meanwhile bitcoin cash is a new altcoin that hasn't gained much popularity yet. Perhaps it will take considerably long time to get to where bitcoin is today if at all it will survive the test of time. Not many people are familiar with bitcoincash. So the inclination of bitcoin being extinct is not really possible. The price is rising continually.
I do agree. I think Bitcoin Cash will stay what it is now : an altcoin, and nothing. By forking from Bitcoin, Bitcoin Cash team has not created a rival Bitcoin, they have deliberaly created an altcoin using the same parameters and a common part of the chain, but that is all. Bitcoin Cash will remain in the shadow of Bitcoin and will never become popular. It will just stay a toy for traders.
