The problem with litecoin is that ,it was not performing for a very long time and recently made a move ,but i am not sure whether it is a good investment,OP is dreaming of a moon value of $200 which i think is not possible with the current situation,it is well and good that they upgraded even though they were not having any scaling issues for the moment and what makes you think that it would hit the roof.
When it comes to scaling, I think it is better to be proactive rather than reactive.
All proclamations that Litecoin did not need the Segwit upgrade are misinformed anyways, because Segwit allows for far more than simply better scaling abilities. For one, the lightning network requires Segwit, and also all of the features that can be built on top of Segwit/LN. The inherent features of both (not including the ones that can be built on top of the protocols) are as follows:
As far as scaling, Segwit, and Litecoin... it is more of a precautionary implementation. It is better for the capacity to be there when you need it rather than waiting to implement it until after you need it.
As far as Segwit, LN, and Litecoin... it is not only about scaling. Ignoring the scaling benefits, there are a lot of other benefits:
LN:Instant transactions
Cross-chain atomic swaps
Lower transaction fees
Reduced blockchain bloat and load
Anonymous transactions by use of onion-style routing
Sub-satoshi payments
Segwit:Fixes malleability issues
Lighter full nodes are possible (you can opt not to download or store signatures, and leave it to the witnesses)
Lighter light nodes use less bandwidth and disk space (don't need to verify signatures)
Miners can maximize fee income and users can more reliably calculate the needed fees
Makes advanced scripting (smart contract) easier
Reduced blockchain bloat and load
