There's seem to be a good accumulation on Litecoin from whales at the moment. It is likely to have a price boost in recent future. There have been technical improvements on the chain. The transaction fees for the coin are low and is readily accepted on most exchange, that's why it's my favorite coin for exchange hoping.
But I'm unsure about the coin on longer run like for over a decade as POW coins are being criticized and favored against due to their energy uses.
I think it's not a significant problem if the user wants to increase their LTC holdings because currently LTC is still very, very worth adding. I think the principle is simple, just keep adding ownership as long as the price is right and reasonable, even if LTC goes up again, wait again when the market gives a discount, if there aren't enough other options available in Altcoin, it's just time to research again to survey prices and potential increases
