I think LTC is also worth considering for investment, and in my view in the future that there will be a lot of price increase trends in each coin, then according to my assumption, now is the best time to invest and still use the right analysis and high accuracy.
Litecoin and bitcoin are likely a couple, and Litecoin plays its main role as a trial tool for bitcoin. From the past, we saw so many features applied successfully on Litecoin network, before bitcoin accepted and implemented them on Bitcoin main net. Lightning Network, Segwit are one of them.
