trading litecoin against bitcoin doesn't make any sense, the prices obviously correlate in fiat value so why would you even bother to pick up the btc/ltc chart...

as already noted itt fundamentally speaking a large community and dedicated devs are a big plus and there is still a lot more room upwards.
they just successfully did atomic swaps with bitcoin and decred and are working with other coins on the same (via, vtc)
so i would definitely advise to pick up litecoin and hodl that shit
