Hell no. bitcoin is not gonna die today or tomorrow maybe 10 years later. Bitcoin value is getting higher right now and I think it's going to take a long way before btc dies.
I guess it will be used for more than 10 years. Bitcoin is not going to die at all. It is nonsense - to compare BTC with Bitcoin Cash. Yes, I can admit that one day people will prefer to deal with ETH but they will use Bitcoin also.
I really can't understand this if there are prople who believe in bitcoin cash thing out there. If there is, this is a serious problem for them. Bitcoin cash is a bad idea and it already failed. Owners try to keep it alive only.
