Major use I see is gambling on casinos, the inherent brand name of second to bitcoin which came before it was taken over by ethereum on the basis of market capital. Much like what DOGE has become some few years back with bigger crypto-based casinos using it as third to bitcoin, although it is not the case anymore with ranks.
Even then if you own some litecoin, dont expect huge movements, it will follow bitcoin and with every small development if it happens, will raise the price by another 50$ max.
