Yes, Litecoin is always a good option and alternative to bitcoin and other major altcoins.
But the problem is Litecoin is directly proportional to bitcoin. That means whenever the bitcoin price goes up Litecoin also goes up. Whenever bitcoin goes down lite coin also goes down.
So it's better to find some other altcoins directionally proportional to Litecoins and invest 50% in those altcoins and 50% in Litecoins.
So it's advised to
compare coins before investing. It is the best practice I suggest to you.
