Litecoin right now is heavily undervalued and its price will bring surprises to everyone in a few months.
it's not even undervalued if you are seeing if the litecoin has no progress this time. That means if this coin overrated. The price can't be determined by how old the crypto is. It must be considered as a undervalued coin when it has bunch of utility usecases but that's different with the litecoin. It's not even having new progress that can be used to create the hype.
Bitcoin is the only thing that makes it alive till this time.
