I personally consider LTC as the most conservative, stable and reliable altcoin. This is why I expect new rise of Litecoin around November 16 (expected Segwit2x hard fork point). It looks like the whole Eliott Wave rising pattern has been already initiated and the new stage is about to begin.
If you have any questions/suggestions guys, I'm happy to discuss
I think BTC/LTC is pretty much balanced to each other right now and will have pretty much correlated price in the nearest future. Both are good investment.
In addition I bet on DASH, ETH and ADA (Cardano) in 2018.
