Problem with KMD is their marketing is shocking, the last video presentation that I saw was so amateurish it was cringe-worthy and saw the price drop by 80C from memory.   
I was invested with them but not anymore. 

If anything they are the poor mans privacy coin, that is about it's main feature the fact that it is the cheapest of them all.

Zcash for me is number 1, as an investment it is growing and growing and is even profitable to mine now at it's current price.
