According to the research, "Litecoin was announced in 2011 with the goal of being the 'silver' to bitcoin's 'gold'. At the time of writing, Litecoin has the highest market cap of any mined cryptocurrency, after bitcoin." Definitely, the currency will be viable for the next decades since its convertible to BTC and current currency, yet in different forms.

Since its inception litecoin was 'just a bitcoin clone', however still here, still strong, with SegWit active in bitcoin and litecoin I believe it makes the two even more valuable.
yes that sounds right.
I think is true that they will be tradable against each other also.
I like Litecoin and what the developers are doing, it was the second
currency I bought into so I have faith in it now.
