I can recommend some goons but I think coin is better for now 
. Undervalued to me means not in the top 100 and not pumped so will quickly give you the ones I know about. It seems that most have pumped a lot or begun meaning there is no best entry for these coins but you can keep them on a short list because once they retrace they should do big things in 2018 still.
-zclassic;recent pump
-cloakcoin;pump started maybe not over
-deeponion;pumping but airdrop not over yet
-xspec;huge pump
-sumocoin;huge pump

But i just try to erase zclassic which already pumped so high and deeponion the developers are still preventing the airdrop participant to dump their coin to the market. i heard so many times about the airdrop participant gets banned if they are sending their coin to the market directly.
