I don't see SegWit having a significant impact on Litecoin. I also suspect it's going to settle back into it's long-term $3.50-$4.50 range quickly after the Bitcoin "potential fork" issues get resolved - and I figure that resolution will also hammer current inflated pricing on most of the altcoins that have seen big rises the past month.
The market already knows the BU fork died. But the market knows that we need scaling else adoption will falter due to very high transaction fees and delayed transaction confirmations.
The miners are not going to enable SegWit on Bitcoin because they are making a lot of money by not doing so. Yet some of those same miners and ASIC manufacturers will make a hell of a lot more money by activating SegWit on Litecoin.
It's happening.
