$100 by december could really happen. If people start aknowledging that SegWit adds immense value to LTC, and if the scaling issue on BTC is not fixed by then, it could mean that plus-value to LTC.
I believe that this is the general sentiment of the market as regarding Litecoin. Its own future is now tied to the coming SegWit implementation as a form of an experimentation for Bitcoin. I am hoping that Litecoin can be coming off with flying colors on this development. I have some Litecoin and I would be happy to see its value rise to the peak.
