I've been considering doing the same. I'm fairly new to the crypto scene but as I've been learning about the various coins over the last few months, I'm not sure you can really go wrong with litecoin, especially if you look at it from a long term perspective like most people do with bitcoin.
Thanks for indirectly nudging me in the right direction!
Be sure to watch for the dips to increase your portfolio the most. If you can keep some funds aside to buy when the price is low or set orders to buy at a low price that's the best way to go.
