Why not Bitcoin or ETH or BNB? Maybe you have the reason why choosing that coin and I believe it was reasonable as you think it was really a good investment. Well, Litecoin is one of the known and profitable coins in the market and so I could say that it was a good choice but I don't think just you need to keep it alone, it was better to invest in Bitcoin together.
But I think you have to wait for the moment when the price correction will come in order to make a buy at a cheaper price.
