I will express, perhaps, an unpopular opinion in this topic, but it seems to me ltc project is slowly dying.
No it is not dying. It is much better than Dogecoin and if you see Dogecoin alive why do you see Litecoin is dying. Litecoin has very good network hashrate and it means a lot about its health
Bitcoin, Ethereum, Litecoin, Dogecoin are a few altcoins from years ago still be alive now and they will be alive next more years.
How much has the hashrate and the number of transactions of ltc changed in recent years? It seems to me that it has decreased, not increased. Correct me if I am wrong. How much has the price changed? Almost nothing and the price is marking time in one place, which means that the coin is not bought. This is a direct indicator that the project is not of interest to investors. It seems to me that the best days of ltc are over.
