I listen to Tone Vays.
Bcash is going to zero for 2 main reasons

1. Increasing the byte size of the transactions causes miners to become more centralized. -- not everyone can afford the extra bandwidth and Storage.
2. Segwit wallet accounts now allow for up to 7 transactions per second. Which is the main reason why each block now has less than one Bitcoin in miners fees. No segwit in bcash.
