IOTA : While internet of things improve this coin will be unstoppable.
WAVES : Because of dex.
XMR/ZEC/KMD : My favourite is Komodo udervalued. Privacy untraceable.
XLM : Because of IBM. Undervalued.
NEO/GAS/RPX : Because of China.
BCH : I think its still undervalued. But you should buy the dips. Sell at resistances.
Oh cool, that's pretty close to my Alt-Portfolio, feeling reassured over here

Quick question: XMR or ZEC? I'm not pretty sure which route to go here and my researches have done only little good so far :S
