I think litecoin is getting slept on right now. I know it is far from the old days of being the second biggest coin in the market but it is literally paving the way for bitcoin right now for the upcoming developments. They were the ones that did segwit first, they were ones that did lightning network first and they are doing whatever they can to improve litecoin first and bitcoin follows their route.

Litecoin is not some sandbox coin that is tested before they move on with bitcoin, it is literally a coin that is improving faster than bitcoin itself and bitcoin only follows the steps of litecoin only after seeing how it works out for them. Litecoin price is really low (which coin isn't) and certainly has a potential to be x10 when the bull comes. Definitely worth a check at least.
