Litecoin ever since Charlie Lee resigned from the team has been a stagnant, and doesn't have any big updates aside from the Mimblewimble update.
I consider Charlie Lee's resignation positive for LTC. It has since then become more decentralized, and more similar to Bitcoin. It's even possible that with Charlie Lee still as undiscuted leader, Litecoin would be today among the coins classified as a "security" by the SEC.
nobody is talking about that coin anymore.
Yes, because the cryptocurrency media is full of paid trash by premined centralized coins with zero innovation, all based on the
PBFT consensus from ... 1999. There are however increasing complaints about this kind of "native advertising" in crypto media, I believe legal action will soon follow. And the recent move by the SEC, and the upcoming MiCa regulation in Europe will cut the market for centralized coins drastically.
Centralized coins in the recent past had an advantage because they can create premined coins out of thin air to pay for bounties, airdrops and marketing. I believe this will perhaps not come to an end still, but slow down considerably.
It's well possible that both LTC and Monero, for me the leading decentralized coins, will be in the top 10 in 1-2 years again, once the dust has cleared and most centralized "security coins" have been dumped down to a fraction of their current value. I'm a bit less positive about Doge but it still holds well. And other
decentralized no-security coins like Grin, Groestlcoin, Peercoin, Namecoin and Signum (ex Burst) could re-enter the top 100.
