No one will know exactly what the price will be but expect it to be a small price, in the $10's of dollars not $100's, since the distribution will be 10-1 per litecoin you hold it will bring litecoin cash's supply WAY higher than litecoin....high supply = lower price.
I would bet they get atleast 1 exchange to honor the fork, but to be the safest you should get your coins to a wallet you control like exodus or litecoin electrum, a wallet where you can find your private key.
Wow! So for this shitty fork you are already assuming the same price as LTC (10:1)! LTC took 10 years to reach to where it is today and someone cooks some code in their moms basement and becomes $100!?
