I think that Litecoin has a good potential to grow. It is cheap, fast and convenient than other cryptocurrency. Moreover, it has activated the segwit and also the lightning network. Many people underestimate litecoin due to many reasons but I do believe that it will soon dominate the marketcap with bitcoin
I don't get why people think Litecoin has value. For a long time, it was called 'the rock' because it just always sunk. I guess its a testnet for Bitcoin changes, but there's already a testnet for that..
