why it's stuck on same price range?
I guess it happens due to the current defi or nft hype, a bunch of people has been carried by the hype and started pouring their money into them. These days most people tend to gamble their luck in other altcoin or the exact newly shitcoin whit hopes it could bring them to insane returns. In other words, litecoin is lacking demands from the market which makes it struggle to break the current ATH.
LTC has been passive lately, also, it is true that the hype has switched from NFT and DeFi projects, causing LTC to remain stagnant, also goes for other coins to be honest, I don't know when the hype will come to an end, seems to me that the NFT hype is just about to begin.
