There was a time when litecoin was under top 10 in market cap. It has many advantages also like less fees in transfer and faster transfer time.
The golden days of Litecoin have passed and it is now nothing more than a coin relied upon bitcoin's name. Litecoin had no advantages at all. These days, litecoin is nothing, and it is not comparable to more scalable blockchains with several features, such as SOL or TON.
I can send my money through the TON blockchain with no fees and it takes only one second to get to its destination. Litecoin is a sluggish blockchain.
Still if we see current position, it is number 21 based on market cap. Why have coins like litecoin failed to make it big ? Did they lack marketing budget and it caused this issue ?
Even its creator had sold his litecoin bags a few years ago, and no further developments were planned. Litecoin lacks everything, starting with TPS, Utility, and so on.
