Litecoin has been around for quite some time now, and its user base is either dormant or declining. Even the recent spike in the crypto market capitalization has failed to boost the LTC. I am afraid that the big whales who were supporting LTC earlier have shifted their loyalty to either ETH or XRP. Right now, LTC is devoid of any media spotlight and despite its obvious advantages such as faster confirmations, the user base is not expanding.
That's odd the subreddit user base has increased by about 42 percent in the last couple months; but, you say the user base is not expanding. Additionally, the quantity of LTC news has grown substantially in the last few months.
I'll agree that Big Whales have more interest in pumping ETH right now. On the other hand XRP volume and price indicate they have moved on. Don't mistaken a pump by whales for loyalty though: they will dump and move on to another coin when it's to their advantage.
