If the currency is dead so BCH also die, BCH may account for only part of the value of the currency, but can't be more than the currency, although say BCH applications will be more and more in the future, but just auxiliary BTC.
if we look at the current conditions then we can notice that BCH has experienced a significant price increase. But that does not mean that Bitcoin will decline and even die. Bitcoin will continue to survive and if Bitcoin is dead / abandoned then all the digital currencies that exist today will also be meaningless again.We may trust BCH as one of Altcoin's current strengths, but we should not be too confident about the situation. because with a belief that is too over then it can make BCH destroyed and crashed. Believe that Bitcoin will be the best and we will now only look for the best Altcoin and BCH is one of the best candidates.
