Replying to Any Bitcoin nerds???

Big changes coming up for Bitcoin in the near future.
Anyone have any speculation on the segwit attempt and if BIP148 will take hold? Will there be a chain split if it fails? What do you think will happen to the value of Bitcoin? Will it effect Litecoin or Ethereum if it takes or fails?
When UASF took hold for Litecoin, it jumped up quite a bit. But that was a less common cryptocurrency and had a low value.
I currently own ~2 bitcoin and ~10 Ether.
