The reason why it slowly dying is because of Charlie Lee public declaration of selling all his holding and major investors decided to sell their holding either to avoid exit scam since the coin creator decided to sell his holding.
Charlie sold to avoid any appearance of having a conflict of interest. Not only that, he told everyone he was going to sell and why. It is ridiculous to say otherwise considering he has remained working on the coin for years.
He claimed to have sold all his holdings to avoid future conflict but him selling his holding was what trigger the future conflict that's hunting the LTC surge/investors trust in the market because he don't do the appropriate announcement and if you're aware of the situation you'll know that there was a lot of discussion about it in the communities.
Exit scam lol ridiculous.
That's what a lot of investors believe till now and a DeFi project owner that does the same thing last year also regret it. The only ridiculous here is a project owner selling all his holding and announcing it publicly the community always misunderstand it.
